Applications/Processing Guide
HOW TO USE THIS SECTION
The Resistive Element
This Applications/Processing Guide is intended to provide
you with points to consider for designing circuits, selecting
trimmers and arranging board layouts, to achieve maximum
performance and long life for your circuits and systems. We
have also included information on steps your manufacturing
engineers can take to preserve circuit reliability.
For example, are you aware that the trimmers and other
mechanical components on your boards may face a more
extreme environment during boardwashing on your own produc-
tion line, than they ever will in use? For those trimmers that may
need to be reset, are you remembering to select and mount the
trimmers to provide easy accessibility?
Trimmers for commercial applications typically have a
resistive element made of carbon or cermet (a combination of
CERamic and METal), or of resistance wire wound on an insulat-
ed copper mandrel.
The main advantages of wirewound trimmers are their low
temperature coefficient, higher power dissipation, lower noise,
tighter resistance tolerance, and, when used as a variable resis-
tor, the excellent current-carrying capacity through the wiper due
to the lower contact resistance. Also, their long-term resistance
stability with time and temperature is slightly better than cermet.
Cermet trimmers provide a wider resistance range (10 ohms
to 5 megohms, versus a maximum of 50K ohms for wirewound).
Also, the wiper output can be set closer to the desired value
since the resistive element presents a continuous contact
surface for the wiper, as opposed to the discrete turns (resolu-
tion) of the wirewound. Other advantages with cermet are the
lower reactance in high-frequency applications, the smaller sizes
available, and the generally lower price than wirewound types.
In this section, you'll find dozens of pointers, reminders
and useful facts that will help you be more knowledgeable and
successful in using trimmers.
TRIMMER BASICS
In its most common form, a trimmer is simply a device
containing a resistive element, and a wiper, or adjustable tap,
contacting the element. The wiper can be mechanically moved
to vary the amount of voltage or resistance in the circuit. The
resistive element is usually laid out in linear or a circular
configuration:

temperature, time, processes, cleaning agents and board types
are found in the electronics industry, you’ll want to test and
verify your own system.

TRIMMING POTENTIOMETERS AND DEFINITIONS
INPUT AND OUTPUT TERMS
The following terms and definitions have been edited from the
Industrial Standard published by the Variable Resistive Components
Institute. It is intended to encourage standardization in communica-
tion and understanding between the manufacturer and user. The
complete standard, including detailed test procedures, is available
upon request.
TOTAL APPLIED VOLTAGE: The total voltage applied between the
designated input terminals.
OUTPUT VOLTAGE: The voltage between the wiper terminal and the
designated reference point. Unless otherwise specified, the
designated reference point is the CCW terminal.
OUTPUT RATIO: The ratio of the output voltage to the designated
input reference voltage. Unless otherwise specified, the refer-
ence voltage is the total applied voltage.
GENERAL TERMS
TRIMMING POTENTIOMETER: An electrical mechanical device with
three terminals. Two terminals are connected to the ends of a
resistive element and one terminal is connected to a movable
conductive contact which slides over the element, thus allowing
the input voltage to be divided as a function of the mechanical
input. It can function as either a voltage divider or rheostat.
LOAD RESISTANCE: An external resistance as seen by the Output
Voltage (connected between the wiper terminal and the desig-
nated reference point.)
ADJ USTMENT TERMS
DIRECTION OF TRAVEL: Clockwise (CW) or counterclockwise
(CCW) rotation when viewing the adjustment end of the poten-
tiometer.
WIREWOUND TRIMMING POTENTIOMETER: A trimming poten-
tiometer characterized by a resistance element made up of
turns of wire on which the wiper contacts only a small portion of
each turn.
CW
CCW
NON-WIREWOUND TRIMMING POTENTIOMETER: A trimming
potentiometer characterized by the continuous nature of the
surface area of the resistance element to be contacted. Contact
is maintained over a continuous, unbroken path. The resistance
is achieved by using material compositions other than wire such
as carbon, conductive plastics, metal film and cermet.

mental extremes of their own production lines, where the conditions
may be much more severe than anything encountered in actual end

"Processability" refers to the ability of the unit to withstand the
production-line processes associated with the finishing steps on the

Settability refers to the ease with which a trimmer can be set
accurately to the position that produces the desired circuit condition.
Where the requirement is for obtaining a highly accurate set-
ting the preference is for cermet — because a small incremental
adjustment in a wirewound unit does not always produce the
expected change in output as the wiper moves off one turn of wire
and onto another.
Setting accuracy is better with a multiturn unit than with a
single-turn. This is especially true when the speed of setting is also
a requirement as on a production line (Figure 2).

General Guidelines for Guarding Against Component Damage
To minimize temperature shock
• Pre-heat boards to maximum acceptable level
• Reduce time in solder
Figure 2.
When accurate setting is required, a multiturn trimmer
can generally be set faster than a single-turn.
To avoid heating components above their maximum rated
temperature
• Use lowest acceptable solder temperature
• Use maximum allowable conveyor speed
• Limit pre-heat temperature to maximum necessary
STABILITY
Stability refers to the ability of the trimmer to remain at the
desired setting. Environmental factors play an important role here:
stability may be affected by temperature exposure, thermal shock/
cycling, humidity, and mechanical shock or vibration.
To limit time of exposure above rated temperature
• Limit time in solder
This is not a matter of concern in most applications, since
Bourns trimmers exhibit excellent stability under all specified condi-
tions. Stability is most often a concern when cermet trimmers are
used in low current "dry" circuits (50uA amps and below). Under
these conditions the contact resistance may vary, making the wiper
appear unstable. This is most noticeable in some rheostat applica-
tions. This can be avoided by using a wirewound unit, or choosing a
cermet trimmer that has been designed for dry-circuit applications.
Bourns applications engineers can assist you on this and other
questions.
• After solder operation, cool board to wash temperature
before it enters wash
To minimize temperature difference between top and bottom of
board
• Apply pre-heat to both top and bottom
To reduce temperature shock on entering the moist environ-
ment of the wash
• Use wash/rinse temperature as near component
temperature as possible
• Extend time between solder process and wash
• Cool board after solder operation, prior to entering wash
ACCESSIBILITY
When selecting a trimmer and determining its placement on the
board, keep in mind the people who will have to use it. Bourns trim-
mers are available in a wide variety of sizes, shapes, configurations,
and placement of adjustment screws. You will usually find a unit on
which the access for adjustment will be convenient for the user.
To minimize temperature variations as component travels
through moisture
• Minimize number of wash/rinse and rinse/dry cycles
• Use heated air for air knives (to counter evaporative
cooling effect)
• Minimize difference between wash and rinse temperature
89
Specifications are subject to change without notice.
Applications/Processing Guide
Keep in mind the different requirements for accessibility
depending on whether adjustment will be done on the assembly line
or in the field; with the board uncovered, in a housing or cabinet, or
on an extender. Also consider whether production-line adjustment
will be done manually or by robotics. A Bourns applications engineer
can advise on special high-speed automatic adjustment features.
•
Smaller Finished Product Size
(addresses demand for miniaturization).
Cost, performance, quality/reliability and size — how are these
factors interrelated and how are they achieved through surface
mounting?
A by-product of SMD technology is the downsizing of compo-
nents. Size reductions range from 25% to 60% , depending upon the
device in question. High PC board densities can be achieved (more
components per square inch of real estate; surface mounted units
can also be assembled on both sides). PC board material savings
alone are substantial. When circuits diminish, external hardware and
other materials follow — further savings. Even freight charges are
decreased by lighter equipment weight and less packaging.
Surface mounted component prices are forecasted to decline,
the result of automated volume production. Volume is directly related
to component standardization. By having a few sizes to cover a large
range of electrical values and/or parameters, large quantities of a
given device can be produced at a much lower per unit cost. Selling
prices fall as volume increases. Component quality is also enhanced
by eliminating many of the variables associated with short produc-
tion runs.
Automatic SMD handling equipment, although capital intensive,
is the single-most effective way to reduce labor costs and increase
yields. Typical "pick and place" machines can assemble compo-
nents 8 to 10 times faster than human assemblers, with virtually no
mistakes. Major direct labor reductions are obvious. The combina-
tion of improved component quality and "mistake-free" component
placement further decreases costs by eliminating the normal rework
of auto-inserted boards.
USABILITY
In selecting a trimmer for a specific application, it's important to
be aware that the catalog contains a myriad of facts about each
model that can assist you in finding the most suitable choice. For
example:
Contact Resistance Variation (CRV) — Under MIL-R 22097 and
MIL-R-39035, the maximum CRV is 3% . All Bourns trimmers meet
this standard (3% or 3 ohms, whichever is greater). For applications
that demand a more rigorous standard, some Bourns trimmers are
rated at 2% or 2 ohms, and many others at 1% or 1 ohm.
Power Rating — The ambient temperature at which the trimmer
will operate has an important bearing on power rating. Power ratings
are usually specified at 70º or 85ºC; at a temperature of 150ºC, the
power rating of many trimmers is reduced to zero.
Temperature Coefficient of Resistance (T.C.) — This specifica-
tion is a measure of how much the resistance changes with a
change in temperature. In many applications a T.C. of ±250PPM/ºC
is acceptable. Typical T.C. specifications for cermet models are
±100PPM/ºC and ±50PPM/ºC for wirewound models.
RELIABILITY
The many advantages of SMD technology will force change
upon both electronic equipment manufacturers and component
suppliers alike. Worldwide competitive prices and performance
pressures will make it happen. Few electronic components will
escape its influence, trimming potentiometers being no exception.
Bourns is committed to SMD conversion, and we intend to be a
leader in surface mounted trimmer devices. Bourns surface mount
trimmers begin on page 12.
One of the greatest challenges facing American manufactur-
ers in the early '90s lies in the area of reliability — a challenge for
component manufacturers and equipment manufacturers alike.
Bourns has been on the leading edge of this effort, both in the area
of instituting new methods and technologies for achieving higher
reliability, and bringing an awareness of the need to other manufac-
turers.
GENERAL NOTES:
SURFACE MOUNTED DEVICES (SMD)
AN EMERGING TECHNOLOGY
Plated-Through Holes: (Ref. MIL-STD-275D).
5.5 Plated-through holes. The difference between the inside diame-
ter of the plated-through hole and the nominal outside diameter
of the inserted lead shall be not greater than 0.028 inch
(0.71mm) or less than 0.010 inch (0.25 mm). Unless otherwise
specified, the hole size shall be the finished plated size after
solder coating or fusing. When flat ribbon leads are mounted
through plated-through holes, the difference between the nomi-
nal thickness of the lead and the inside diameter of the plated-
through hole shall not exceed 0.028 inch (0.71 mm).
Surface mounting of electronic components represents another
significant advance in PC board processing. Many U.S. companies
have expressed an interest in SMD assembly methods to replace the
often troublesome and costly techniques now used with leaded
components. Unfortunately, for a number of reasons, this interest
has not resulted to date in a major commitment to SMD handling
equipment.
There are direct and indirect benefits associated with surface
mounting. Since the direct benefits are outgrowths of the indirect
ones, some explanation of these interrelated factors is required in
order to understand this complex, highly technical and investment
intensive subject. Further, a listing of the primary advantages will
make additional comments on Japan's SMD usage and growth
unnecessary.
In capsule format, the primary advantages (with comments on
secondary benefits) are:
•
•
•
Lower End-Equipment Cost
(positions OEM's for aggressive pricing to achieve market
penetration).
Superior Product Performance
(satisfies user requirements for improved operational
performance).
Improved Product Quality and Reliability
(creates confidence factor which easily translates to
increased demand or sales).
