—SOLDERING
METHOD
SOLDERING CONDITIONS
REMARK
— Solder no closer than 2mm from
the base of the package
DIP
Bath temperature: 260 max
Immersion time: within 5 sec
SOLDERING
— Using soldering flux,” RESIN FLUX”
is recommended.
—During soldering, take care not to
press the tip of iron against the
Soldering iron: 30W or smaller
SOLDERING
Temperature at tip of iron: 260℃ or lower PIN.
Soldering time: within 5 sec. (To prevent heat from being
transferred directly to the PIN.)
IRON
1) When soldering the PIN of Display in a jig that the package is fixed with a panel (See fIg.1), be
careful not to stress the PIN with iron tip. When soldering Display in a condition that the
package is fixed with a panel, be careful not to cling and stress the surface of Display on the
panel to avoid damaging the Display.
Fig.1
Regarding solution in the tinning oven for product-tinning, compound sub-solution made of tin
& copper and silver is proposed with the temperature of Celsius 260. The proportion of the
alloyed solution is tin 95.5: copper 3.5: silver 0.5 by percentage. The time of tinning is
constantly 3 seconds.

2) Similarly, when a jig is used to solder the Display to PC board, take care as much as possible to
avoid steering the PIN (See Fig.2).
Fig.2
3) Repositioning after soldering should be avoided as much as possible. If inevitable, be sure to
preserve the soldering conditions with irons stated above: select a best-suited method that
assures the least stress to the Display.
4) PIN cutting after soldering should be performed only after the Display temperature has returned
to normal temperature.
—LED MOUNTING METHOD
1) When mounting the Display by using a case, as shown Fig.3, ensure that the mounting holds
on the PC board match the pitch of the PIN correctly-tolerance of dimensions of the respective
components including the Display should be taken into account especially when designing the
case, PC board, etc. to prevent pitch misalignment between the PIN and board holes, the
diameter of the board holes should be slightly larger than the size of the PIN. Alternatively, the
shape of the holes should be made oval. (See Fig.3)

2) Use Display with holder made of resin (Fig.4) to position the PIN.
Fig.4
—FORMED LEAD
1) The PIN should be bent at a point located at least 2mm away from the package. Bending
should be performed with base fixed means of a jig or pliers (Fig.5)
Fig.5
2) Forming PIN should be carried our prior to soldering and never during or after soldering.
3) Form the PIN to ensure alignment between the PIN and the hole on board, so that stress
against the Display is prevented. (Fig.6)

—LEAD STRENGTH
1) Bend strength
Do not bend the PIN more than twice. (Fig.7)
Fig.7
2) Tensile strength (@Room Temperature)
If the force is 1kg or less, there will be no problem. (Fig.8)
ok!

—HANDLING PRECAUTIONS
Although rigid against vibration, the Display may damaged or scratched if dropped. So take care
when handling.
—CHEMICAL RESISTANCE
1) Avoid exposure to chemicals as it may attack the Display surface and cause discoloration.
2) When washing is required, refer to the following table for the proper chemical to be used.

— STORAGE
1) The Display should be stored at 30℃ or less and 70% RH or less after being shipped from
PARA and the storage life limits are 3 months.
2) PARA Display lead frames are comprised of a stannum plated iron alloy. The silver surface
may be affected by environments which contain corrosive gases and so on. Please avoid
conditions which may cause the Display to corrode, tarnish or discolor. This corrosion or
discoloration may cause difficulty during soldering operations. It is recommended that the
Display be used as soon as possible.
3) Please avoid rapid transitions in ambient temperature, especially, in high humidity
environments where condensation can occur.
— HEAT GENERATION
1) Thermal design of the end product is of paramount importance. Please consider the heat
generation of the Display when making the system design. The coefficient of temperature
increase per input electric power is affected by the thermal resistance of the circuit board and
density of Display placement on the board, as well as other components. It is necessary to
avoid intense heat generation and operate within the maximum ratings given in this
specification.
2) The operating current should be decided after considering the ambient maximum temperature
of Display .
—OTHERS
1) Care must be taken to ensure that the reverse voltage will not exceed the absolute maximum
rating when using the Display with matrix drive.
2) Flashing lights have been known to cause discomfort in people; you can prevent this by taking
precautions during use. Also, people should be cautious when using equipment that has had
Display incorporated into it.
3) The Display described in this brochure are intended to be used for ordinary electronic
equipment (such as office equipment, communications equipment, measurement instruments
and household appliances). Consult PARA’s sales staff in advance for information on the
applications in which exceptional quality and reliability are required , particularly when the
failure or malfunction of the Display may directly jeopardize life or health (such as for airplanes,
aerospace, submersible repeaters, nuclear reactor control systems, automobiles, traffic control
equipment, life support systems and safety devices).

4) User shall not reverse engineer by disassembling or analysis of the Display without having
prior written consent from PARA. When defective Display are found, the User shall inform
PARA directly before disassembling or analysis.
5) The formal specifications must be exchanged and signed by both parties before large volume
purchase begins.
6) The appearance and specifications of the product may be modified for improvement without
notice.
