ꢀ NOTE
To be fully compliant with all applicable DDR SDRAM memory specifications, the board
should be populated with DIMMs that support the Serial Presence Detect (SPD) data
structure. This enables the BIOS to read the SPD data and program the chipset to
accurately configure memory settings for optimum performance. If non-SPD memory
is installed, the BIOS will attempt to correctly configure the memory settings, but
performance and reliability may be impacted or the DIMMs may not function under the
determined frequency.

Intel Desktop Board DG41TY Technical Product Specification
1.5.1
Memory Configurations
The Intel 82G41 GMCH supports the following types of memory organization:
•
Dual channel (Interleaved) mode. This mode offers the highest throughput for
real world applications. Dual channel mode is enabled when the installed memory
capacities of both DIMM channels are equal. Technology and device width can vary
from one channel to the other but the installed memory capacity for each channel
must be equal. If different speed DIMMs are used between channels, the slowest
memory timing will be used.
•
•
Single channel (Asymmetric) mode. This mode is equivalent to single channel
bandwidth operation for real world applications. This mode is used when only a
single DIMM is installed or the memory capacities are unequal. Technology and
device width can vary from one channel to the other. If different speed DIMMs are
used between channels, the slowest memory timing will be used.
Flex mode. This mode provides the most flexible performance characteristics.
The bottommost DRAM memory (the memory that is lowest within the system
memory map) is mapped to dual channel operation; the topmost DRAM memory
(the memory that is nearest to the 8 GB address space limit), if any, is mapped to
single channel operation. Flex mode results in multiple zones of dual and single
channel operation across the whole of DRAM memory. To use flex mode, it is
necessary to populate both channels.

1.6.1
Intel G41 Graphics Subsystem
The Intel G41 Express chipset contains two separate, mutually exclusive graphics
options. Either the Intel Graphics Media Accelerator X4500 (Intel GMA X4500)
graphics controller (contained within the 82G41 GMCH) is used, or a PCI Express x16
add-in card can be used. When a PCI Express x16 add-in card is installed, the Intel
GMA X4500 graphics controller is disabled.
1.6.1.1
Intel® Graphics Media Accelerator X4500 Graphics
Controller
The Intel GMA X4500HD graphics controller features the following:
•
•
High quality texture engine
⎯ DirectX10* and OpenGL* 2.0 compliant
⎯ Shader Model 4.0
3D Graphics Rendering enhancements
⎯ 1.6 dual texture GigaPixel/sec max fill rate
⎯ 16-bit and 32-bit color
⎯ Vertex cache
•
Video
⎯ Hi-Definition content at up to 1080p resolution
⎯ Dynamic Video Memory Technology (DVMT) 5.0 uses system memory
depending on the OS and the amount of memory installed
18
Product Description
•
Display
⎯ Supports digital and analog displays up to 2048 x 1536 at 75 Hz refresh
(QXGA); also supports 1920 x 1080 resolution for full High Definition video
playback quality
⎯ Dual independent display support
1.6.1.2
Dynamic Video Memory Technology (DVMT 5.0)
DVMT enables enhanced graphics and memory performance through highly efficient
memory utilization. DVMT ensures the most efficient use of available system memory
for maximum 2-D/3-D graphics performance. The amount of system memory
allocated to DVMT varies depending on the amount of total system memory installed
as well as the operating system being used. For Windows Vista, a minimum of 128 MB
can be allocated to DVMT and a maximum of over 2 GB can be allocated to DVMT with
the correct amount of memory installed. DVMT returns system memory back to the
operating system when the additional system memory is no longer required by the
graphics subsystem.
DVMT will always use a minimal fixed portion of system physical memory (as set in the
BIOS Setup program) for compatibility with legacy applications. An example of this
would be when using VGA graphics under DOS. Once loaded, the operating system
and graphics drivers allocate additional system memory to the graphics buffer as
needed for performing graphics functions.
NOTE
ꢀ
The use of DVMT requires operating system driver support.
1.6.1.3
Configuration Modes
The video modes supported by this board are based on the Extended Display
Identification Data (EDID) modes of the monitor to which the system is connected.
Standard monitors are assumed.

Advanced Digital Display (ADD2/MEC/ADD2+) Card
Support
The GMCH routes two multiplexed SDVO ports that are each capable of driving up to a
270 MHz pixel clock to the PCI Express x16 connector. When an ADD2/MEC/ADD2+
card is detected, the Intel GMA X4500 graphics controller is enabled and the PCI
Express x16 connector is configured for SDVO mode. SDVO mode enables the SDVO
ports to be accessed by the ADD2/MEC/ADD2+ card. An ADD2/MEC/ADD2+ card can
either be configured to support simultaneous display or can be configured to support
dual independent display as an extended desktop configuration with different color
depths and resolutions with DVI analog output only. ADD2/MEC/ADD2+ cards can be
designed to support the following configurations:
•
•
•
•
Low Voltage Differential Signaling (LVDS)
Single device operating in dual channel mode
HDTV output
HDMI support (when used with the HD Audio Link header)

1.6.3
Serial ATA Interfaces
The board provides four Serial ATA (SATA) connectors, which support one device per
connector.
1.6.3.1
Serial ATA Support
The board’s Serial ATA controller offers four independent Serial ATA ports with a
theoretical maximum transfer rate of 3 Gbits/sec per port. One device can be installed
on each port for a maximum of four Serial ATA devices. A point-to-point interface is
used for host to device connections, unlike Parallel ATA IDE which supports a
master/slave configuration and two devices per channel.
For compatibility, the underlying Serial ATA functionality is transparent to the
operating system. The Serial ATA controller can operate in both legacy and native
modes. In legacy mode, standard IDE I/O and IRQ resources are assigned (IRQ 14
and 15). In Native mode, standard PCI Conventional bus resource steering is used.
Native mode is the preferred mode for configurations using the Windows* XP
operating system.
NOTE
ꢀ
Many Serial ATA drives use new low-voltage power connectors and require adapters or
power supplies equipped with low-voltage power connectors.

Parallel IDE Controller
The Parallel ATA IDE controller has one bus-mastering Parallel ATA IDE interface. The
Parallel ATA IDE interface supports the following modes:
•
Programmed I/O (PIO): processor controls data transfer.
8237-style DMA: DMA offloads the processor, supporting transfer rates of up to
16 MB/sec.
Ultra DMA: DMA protocol on IDE bus supporting host and target throttling and
transfer rates of up to 33 MB/sec.
ATA-66: DMA protocol on IDE bus supporting host and target throttling and
transfer rates of up to 66 MB/sec. ATA-66 protocol is similar to Ultra DMA and is
device driver compatible.
•
•
•
•
ATA-100: DMA protocol on IDE bus allows host and target throttling. The ATA-100
logic can achieve read transfer rates up to 100 MB/sec and write transfer rates up
to 88 MB/sec.
ꢀ NOTE
ATA-66 and ATA-100 are faster timings and require a specialized cable to reduce
reflections, noise, and inductive coupling.
The Parallel ATA IDE interface also supports ATAPI devices (such as CD-ROM drives)
and ATA devices. The BIOS supports Logical Block Addressing (LBA) and Extended
Cylinder Head Sector (ECHS) translation modes. The drive reports the transfer rate
and translation mode to the BIOS.

1.13.1.1 System States and Power States
Under ACPI, the operating system directs all system and device power state
transitions. The operating system puts devices in and out of low-power states based
on user preferences and knowledge of how devices are being used by applications.
Devices that are not being used can be turned off. The operating system uses
information from applications and user settings to put the system as a whole into a
low-power state.
Table 8 lists the power states supported by the board along with the associated
system power targets. See the ACPI specification for a complete description of the

1.13.2.3 LAN Wake Capabilities
CAUTION
For LAN wake capabilities, the +5 V standby line from the power supply must be
capable of providing adequate +5 V standby current. Failure to provide adequate
standby current when implementing LAN wake capabilities can damage the power
supply.
LAN wake capabilities enable remote wake-up of the computer through a network.
The LAN subsystem PCI bus network adapter monitors network traffic at the Media
Independent Interface. Upon detecting a Magic Packet* frame, the LAN subsystem
asserts a wake-up signal that powers up the computer. Depending on the LAN
implementation, the board supports LAN wake capabilities with ACPI in the following
ways:
•
•
•
The PCI Express WAKE# signal
The PCI bus PME# signal for PCI 2.3 compliant LAN designs
The onboard LAN subsystem
35
Intel Desktop Board DG41TY Technical Product Specification
1.13.2.4 Instantly Available PC Technology
CAUTION
For Instantly Available PC technology, the +5 V standby line from the power supply
must be capable of providing adequate +5 V standby current. Failure to provide
adequate standby current when implementing Instantly Available PC technology can
damage the power supply.
Instantly Available PC technology enables the board to enter the ACPI S3 (Suspend-to-
RAM) sleep-state. While in the S3 sleep-state, the computer will appear to be off (the
power supply is off, and the front panel LED is amber if dual colored, or off if single
colored.) When signaled by a wake-up device or event, the system quickly returns to
its last known wake state. Table 9 on page 33 lists the devices and events that can
wake the computer from the S3 state.
The board supports the PCI Bus Power Management Interface Specification. Add-in
boards that also support this specification can participate in power management and
can be used to wake the computer.
The use of Instantly Available PC technology requires operating system support and
PCI 2.3 compliant add-in cards and drivers.
1.13.2.5 Wake from USB
USB bus activity wakes the computer from ACPI S3 state.
NOTE
ꢀ
Wake from USB requires the use of a USB peripheral that supports Wake from USB.
1.13.2.6 Wake from PS/2 Devices
PS/2 device activity wakes the computer from an ACPI S1, S3, and S5 state.
1.13.2.7 PME# Signal Wake-up Support
When the PME# signal on the PCI bus is asserted, the computer wakes from an ACPI
S3, S4, or S5 state (with Wake on PME enabled in BIOS).
1.13.2.8 WAKE# Signal Wake-up Support
When the WAKE# signal on the PCI Express bus is asserted, the computer wakes from
an ACPI S3, S4, or S5 state.

Memory Map
2.1.1
Addressable Memory
The board utilizes 8 GB of addressable system memory. Typically the address space
that is allocated for PCI Conventional bus add-in cards, PCI Express configuration
space, BIOS (SPI Flash), and chipset overhead resides above the top of DRAM (total
system memory). On a system that has 8 GB of system memory installed, it is not
possible to use all of the installed memory due to system address space being
allocated for other system critical functions. These functions include the following:
•
•
•
•
•
•
BIOS/SPI Flash (8 Mbits)
Local APIC (19 MB)
Direct Media Interface (40 MB)
Front side bus interrupts (17 MB)
PCI Express configuration space (256 MB)
GMCH base address registers, internal graphics ranges, PCI Express ports (up to
512 MB)
•
•
Memory-mapped I/O that is dynamically allocated for PCI Conventional and PCI
Express add-in cards
Base graphics memory support (1 MB or 8 MB)
NOTE
ꢀ
System resources and hardware (such as PCI and PCI Express*) require physical
memory address locations that can reduce available addressable system memory. This
could result in a reduction of as much as 1 GB or more of physical addressable
memory being available to the operating system and applications, depending on the
system configuration and operating system.

Add-in Card Connectors
The board has the following add-in card connectors:
•
One PCI Express x16 connector:
⎯ Supports PCI Express 1.1 frequency of 1.25 GHz resulting in 2.5 Gb/s each
direction (500 MB/s total). The maximum theoretical bandwidth on the
interface is 4 GB/s in each direction simultaneously, for an aggregate of 8 GB/s
when operating in x16 mode.
•
•
PCI Express x1: one PCI Express x1 connector. The x1 interface supports
simultaneous transfer speeds up to 250 Mbytes/sec of peak bandwidth per
direction and up to 500 MB/sec concurrent bandwidth.
PCI Conventional (rev 2.3 compliant) bus: two PCI Conventional bus add-in card
connectors. The SMBus is routed to all PCI Conventional bus connectors. PCI
Conventional bus add-in cards with SMBus support can access sensor data and
other information residing on the board.
Note the following considerations for the PCI Conventional bus connectors:
•
•
All of the PCI Conventional bus connectors are bus master capable.
SMBus signals are routed to all PCI Conventional bus connectors. This enables PCI
Conventional bus add-in boards with SMBus support to access sensor data on the
board. The specific SMBus signals are as follows:
⎯ The SMBus clock line is connected to pin A40.
⎯ The SMBus data line is connected to pin A41.

Power Supply Connectors
The board has the following power supply connectors:
•
Main power – a 2 x 12 connector. This connector is compatible with 2 x 10
connectors previously used on Intel Desktop boards. The board supports the use
of ATX12V power supplies with either 2 x 10 or 2 x 12 main power cables. When
using a power supply with a 2 x 10 main power cable, attach that cable on the
rightmost pins of the main power connector, leaving pins 11, 12, 23, and 24
unconnected.
•
Processor core power – a 2 x 2 connector. This connector provides power
directly to the processor voltage regulator and must always be used. Failure to do
so will prevent the board from booting.

Failure to ensure appropriate airflow may result in reduced performance of both the
processor and/or voltage regulator or, in some instances, damage to the board. For a
list of chassis that have been tested with Intel desktop boards please refer to the
following website:
http://developer.intel.com/design/motherbd/cooling.htm
All responsibility for determining the adequacy of any thermal or system design
remains solely with the reader. Intel makes no warranties or representations that
merely following the instructions presented in this document will result in a system
with adequate thermal performance.
CAUTION
Ensure that the ambient temperature does not exceed the board’s maximum operating
temperature. Failure to do so could cause components to exceed their maximum case
temperature and malfunction. For information about the maximum operating
temperature, see the environmental specifications in Section 2.8.
56
Technical Reference
CAUTION
Ensure that proper airflow is maintained in the processor voltage regulator circuit.
Failure to do so may result in damage to the voltage regulator circuit. The processor

3 Overview of BIOS Features
3.1
Introduction
The board uses an Intel BIOS that is stored in the Serial Peripheral Interface Flash
Memory (SPI Flash) and can be updated using a disk-based program. The SPI Flash
contains the BIOS Setup program, POST, the PCI auto-configuration utility, and Plug
and Play support.
The BIOS displays a message during POST identifying the type of BIOS and a revision
code. The initial production BIOSs are identified as TYG4110H.86A.
When the BIOS Setup configuration jumper is set to configure mode and the computer
is powered-up, the BIOS compares the CPU version and the microcode version in the
BIOS and reports if the two match.
The BIOS Setup program can be used to view and change the BIOS settings for the
computer. The BIOS Setup program is accessed by pressing the <F2> key after the
Power-On Self-Test (POST) memory test begins and before the operating system boot
begins. The menu bar is shown below.

BIOS Flash Memory Organization
The Serial Peripheral Interface Flash Memory (SPI Flash) includes an 8 Mbit
(1024 KB) flash memory device.
Resource Configuration
3.3.1
PCI Autoconfiguration
The BIOS can automatically configure PCI devices. PCI devices may be onboard or
add-in cards. Autoconfiguration lets a user insert or remove PCI cards without having
to configure the system. When a user turns on the system after adding a PCI card,
the BIOS automatically configures interrupts, the I/O space, and other system
resources. Any interrupts set to Available in Setup are considered to be available for
use by the add-in card.
62
Overview of BIOS Features
3.3.2
PCI IDE Support
The IDE interface supports hard drives up to ATA-66/100 and recognizes any ATAPI
compliant devices, including CD-ROM drives, tape drives, and Ultra DMA drives.
To use ATA-66/100 features the following items are required:
•
•
•
An ATA-66/100 peripheral device
An ATA-66/100 compatible cable
ATA-66/100 operating system device drivers
NOTE
ꢀ
Do not connect an ATA device as a slave on the same IDE cable as an ATAPI master
device. For example, do not connect an ATA hard drive as a slave to an ATAPI
CD-ROM drive.
3.4
System Management BIOS (SMBIOS)
SMBIOS is a Desktop Management Interface (DMI) compliant method for managing
computers in a managed network.
The main component of SMBIOS is the Management Information Format (MIF)
database, which contains information about the computing system and its
components. Using SMBIOS, a system administrator can obtain the system types,
capabilities, operational status, and installation dates for system components. The
MIF database defines the data and provides the method for accessing this information.
The BIOS enables applications such as third-party management software to use
SMBIOS. The BIOS stores and reports the following SMBIOS information:
•
BIOS data, such as the BIOS revision level
•
•
•
Fixed-system data, such as peripherals, serial numbers, and asset tags
Resource data, such as memory size, cache size, and processor speed
Dynamic data, such as event detection and error logging
Non-Plug and Play operating systems require an additional interface for obtaining the
SMBIOS information. The BIOS supports an SMBIOS table interface for such operating
systems. Using this support, an SMBIOS service-level application running on a
non-Plug and Play operating system can obtain the SMBIOS information. Additional
board information can be found in the BIOS under the Additional Information header
under the Main BIOS page.
3.5
Legacy USB Support
Legacy USB support enables USB devices to be used even when the operating
system’s USB drivers are not yet available. Legacy USB support is used to access the
BIOS Setup program, and to install an operating system that supports USB. By
default, Legacy USB support is set to Enabled.
Legacy USB support operates as follows:
63
Intel Desktop Board DG41TY Technical Product Specification
1. When you apply power to the computer, legacy support is disabled.
2. POST begins.
3. Legacy USB support is enabled by the BIOS allowing you to use a USB keyboard to
enter and configure the BIOS Setup program and the maintenance menu.
4. POST completes.
5. The operating system loads. While the operating system is loading, USB
keyboards and mice are recognized and may be used to configure the operating
system. (Keyboards and mice are not recognized during this period if Legacy USB
support was set to Disabled in the BIOS Setup program.)
6. After the operating system loads the USB drivers, all legacy and non-legacy USB
devices are recognized by the operating system, and Legacy USB support from the
BIOS is no longer used.
7. Additional USB legacy feature options can be access by using Intel Integrator
Toolkit.
To install an operating system that supports USB, verify that Legacy USB support in
the BIOS Setup program is set to Enabled and follow the operating system’s
installation instructions.
64
Overview of BIOS Features
3.6
BIOS Updates
The BIOS can be updated using either of the following utilities, which are available on
the Intel World Wide Web site:
•
Intel® Express BIOS Update utility, which enables automated updating while in the
Windows environment. Using this utility, the BIOS can be updated from a file on a
hard disk, a USB drive (a flash drive or a USB hard drive), or a CD-ROM, or from
the file location on the Web.
•
Intel® Flash Memory Update Utility, which requires booting from DOS. Using this
utility, the BIOS can be updated from a file on a hard disk, a USB drive (a flash
drive or a USB hard drive), or a CD-ROM.
Both utilities verify that the updated BIOS matches the target system to prevent
accidentally installing an incompatible BIOS.
NOTE
ꢀ
Review the instructions distributed with the upgrade utility before attempting a BIOS
update.
For information about
Refer to
BIOS update utilities
http://support.intel.com/support/motherboards/desktop/s

The BIOS Setup program and help messages are supported in US English. Additional
languages are available in the Intel® Integrator Toolkit utility. Check the Intel website
for details.
65
Intel Desktop Board DG41TY Technical Product Specification
3.6.2
Custom Splash Screen
During POST, an Intel® splash screen is displayed by default. This splash screen can
be augmented with a custom splash screen. The Intel® Integrator Toolkit or Intel®
Integrator Assistant that are available from Intel can be used to create a custom
splash screen.
NOTE
ꢀ
If you add a custom splash screen, it will share space with the Intel branded logo.

BIOS Recovery
It is unlikely that anything will interrupt a BIOS update; however, if an interruption
occurs, the BIOS could be damaged. Table 34 lists the drives and media types that
can and cannot be used for BIOS recovery. The BIOS recovery media does not need
to be made bootable.

Overview of BIOS Features
3.8
Boot Options
In the BIOS Setup program, the user can choose to boot from a diskette drive, hard
drive, USB drive, USB flash drive, CD-ROM, or the network. The default setting is for
the diskette drive to be the first boot device, the hard drive second, and the ATAPI
CD-ROM third. The fourth device is disabled.
3.8.1
CD-ROM Boot
Booting from CD-ROM is supported in compliance to the El Torito bootable CD-ROM
format specification. Under the Boot menu in the BIOS Setup program, ATAPI CD-
ROM is listed as a boot device. Boot devices are defined in priority order. Accordingly,
if there is not a bootable CD in the CD-ROM drive, the system will attempt to boot
from the next defined drive.
3.8.2
Network Boot
The network can be selected as a boot device. This selection allows booting from the
onboard LAN or a network add-in card with a remote boot ROM installed.
Pressing the <F12> key during POST automatically forces booting from the LAN. To
use this key during POST, the User Access Level in the BIOS Setup program's Security
menu must be set to Full.
3.8.3
Booting Without Attached Devices
For use in embedded applications, the BIOS has been designed so that after passing
the POST, the operating system loader is invoked even if the following devices are not
present:
•
•
•
Video adapter
Keyboard
Mouse
3.8.4
Changing the Default Boot Device During POST
Pressing the <F10> key during POST causes a boot device menu to be displayed. This
menu displays the list of available boot devices (as set in the BIOS setup program’s
Boot Device Priority Submenu). Table 35 lists the boot device menu options.

Adjusting Boot Speed
These factors affect system boot speed:
•
•
Selecting and configuring peripherals properly
Optimized BIOS boot parameters
3.9.1
Peripheral Selection and Configuration
The following techniques help improve system boot speed:
•
•
•
Choose a hard drive with parameters such as “power-up to data ready” less than
eight seconds, that minimize hard drive startup delays.
Select a CD-ROM drive with a fast initialization rate. This rate can influence POST
execution time.
Eliminate unnecessary add-in adapter features, such as logo displays, screen
repaints, or mode changes in POST. These features may add time to the boot
process.
•
Try different monitors. Some monitors initialize and communicate with the BIOS
more quickly, which enables the system to boot more quickly.
3.9.2
BIOS Boot Optimizations
Use of the following BIOS Setup program settings reduces the POST execution time.
•
In the Boot Menu, set the hard disk drive as the first boot device. As a result, the
POST does not first seek a diskette drive, which saves about one second from the
POST execution time.
•
In the Peripheral Configuration submenu, disable the LAN device if it will not be
used. This can reduce up to four seconds of option ROM boot time.
NOTE
ꢀ
It is possible to optimize the boot process to the point where the system boots so
quickly that the Intel logo screen (or a custom logo splash screen) will not be seen.
Monitors and hard disk drives with minimum initialization times can also contribute to
a boot time that might be so fast that necessary logo screens and POST messages
cannot be seen.
This boot time may be so fast that some drives might be not be initialized at all. If
this condition should occur, it is possible to introduce a programmable delay ranging
from three to 30 seconds (using the Hard Disk Pre-Delay feature of the Advanced
Menu in the Drive Configuration Submenu of the BIOS Setup program).
68
Overview of BIOS Features
3.10 BIOS Security Features
The BIOS includes security features that restrict access to the BIOS Setup program
and who can boot the computer. A supervisor password and a user password can be
set for the BIOS Setup program and for booting the computer, with the following
restrictions:
•
•
•
•
The supervisor password gives unrestricted access to view and change all the
Setup options in the BIOS Setup program. This is the supervisor mode.
The user password gives restricted access to view and change Setup options in the
BIOS Setup program. This is the user mode.
If only the supervisor password is set, pressing the <Enter> key at the password
prompt of the BIOS Setup program allows the user restricted access to Setup.
If both the supervisor and user passwords are set, users can enter either the
supervisor password or the user password to access Setup. Users have access to
Setup respective to which password is entered.
•
Setting the user password restricts who can boot the computer. The password
prompt will be displayed before the computer is booted. If only the supervisor
password is set, the computer boots without asking for a password. If both
passwords are set, the user can enter either password to boot the computer.
For enhanced security, use different passwords for the supervisor and user
passwords.
•
•
Valid password characters are A-Z, a-z, and 0-9. Passwords may be up to
16 characters in length.
Table 36 shows the effects of setting the supervisor password and user password.
This table is for reference only and is not displayed on the screen.

Port 80h POST Codes
During the POST, the BIOS generates diagnostic progress codes (POST codes) to I/O
port 80h. If the POST fails, execution stops and the last POST code generated is left
at port 80h. This code is useful for determining the point where an error occurred.
Displaying the POST codes requires a PCI bus add-in card, often called a POST card.
The POST card can decode the port and display the contents on a medium such as a
seven-segment display.
NOTE
ꢀ
The POST card must be installed in PCI bus connector 1.
The following tables provide information about the POST codes generated by the BIOS.

Lead Free Intel Desktop Board
This Intel Desktop Board is a European Union Restriction of Hazardous Substances (EU
RoHS Directive 2002/95/EC) compliant product. EU RoHS restricts the use of six
materials. One of the six restricted materials is lead.
This board is lead free although certain discrete components used on the board
contain a small amount of lead which is necessary for component performance and/or
reliability. This Intel Desktop Board is referred to as “Lead-free second level
interconnect.” The board substrate and the solder connections from the board to the
components (second-level connections) are all lead free.
China bans the same substances and has the same limits as EU RoHS; however it
requires different product marking and controlled substance information. The required
mark shows the Environmental Friendly Usage Period (EFUP). The EFUP is defined as
the number of years for which controlled listed substances will not leak or chemically
deteriorate while in the product.
Table 43 shows the various forms of the “Lead-Free 2nd Level Interconnect” mark as it
appears on the board and accompanying collateral.
