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? 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: The Resistive Element 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.

Specifications are subject to change without notice. 84 This application note is designed to provide step-by-step processing recommendations. It covers the popular SMC soldering processes currently in use and provides recommenda- tions and cautions for each step. Since many variations of temperature, time, processes, cleaning agents and board types are found in the electronics industry, you’ll want to test and verify your own system. The process steps, recommendations and cautions are based on Bourns Trimpot surveys of SMC users, equipment manufacturers and materials suppliers. Also, comments reflect results of Bourns’ testing. Our findings suggest the following soldering and cleaning processes: 1. SOLDERING - Forced Hot Air, Convection, IR, Vapor Phase (In-Line), Wave (Single and Dual) 2. CLEANING - Solvent, Aqueous, Semi-Aqueous, No-Clean On the facing page are the common methods, materials and maximum temperature/time parameters for soldering and cleaning processes. Reflow GENERAL Use the optimum solder paste for the pattern, printing process, solder paste density and solder joint quality. RECOMMENDED Use Sn 63% Pb 37% solder paste. Use 8 to 10 mil thickness for solder paste print. CAUTION Since solder paste usually contains a high percentage of activators, you must ensure adequate cleaning to remove all residues, unless no-clean (low solids) paste is used. Solder Paste Printing Adhesive Application Flow (Wave) GENERAL The adhesive must hold the SM Component (SMC) in correct orientation upon place- ment and maintain correct trimmer position during physical handling before final solder processing. RECOMMENDED To assure positional stability, place a single dot of epoxy under the SMC. CAUTION Stability after placement is a direct function of the volume of adhesive used. Use enough epoxy to assure stability through the cure process. Avoid overflow of epoxy to solder pad and terminal areas. Adhesive Cure Flow (Wave) GENERAL Use heat/time cure method with either convection oven or infrared radiation. RECOMMENDED Cure using the temperature and times recommended by the adhesive manufacturer. CAUTION Use enough cure time to assure complete adhesive transition from fluid to solid. Flux Application Flow (Wave) GENERAL Use the correct flux to remove surface oxides, prevent reoxidation and promote wetting. RECOMMENDED

• RMA
• No-clean SRB (Synthetic resin based)
• OA (Organic Acid) (See caution) CAUTION Avoid highly activated fluxes. Consult factory before using OA. SMC Placement GENERAL Use pick-and-place equipment with vacuum nozzle ID size that allows adequate suction to pick the SMC out of the embossed cavity. RECOMMENDED The nozzle inside diameter (ID) should not exceed .100 in. (2.54mm) to ensure adequate suction and part alignment. CAUTION Assure parts are placed so that all terminals are equidistant (<4 mils) from the solder pads. Align terminals with solder belt direction of travel to avoid body shadowing effects during flow soldering. EPOXY Soldering And Cleaning Processes

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. 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. 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. 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. RESISTANCE ELEMENT: A continuous, unbroken length of resistive material without joints, bonds or welds except at the junction of the element and the electrical terminals connected to each end of the element, or at an intermediate point such as a center tap. ADJUSTMENT SHAFT: The mechanical input member of a trimming potentiometer which when actuated causes the wiper to traverse the resistance element resulting in a change in output voltage or resistance.

STOP-CLUTCH: A device which allows the wiper to idle at the ends of the resistive element without damage as the adjustment shaft continues to be actuated in the same direction. STOP – SOLID: A positive limit to mechanical and/or electrical adjustment. STACKING: The mounting of one trimming potentiometer adjacent to or on top of another utilizing the same mounting hardware. THEORETICAL RESOLUTION: (Wirewound only) The theoretical measurement of sensitivity to which the output ratio may be adjusted; the reciprocal of the number of turns of wire in resis- tance winding expressed as a percentage.

Approximately 85% of the heating is provided by free convection to reflow solder on exposed PC boards. Dual Wave System — Utilizes two parallel solder waves. The first is a turbulent wave followed by a laminar wave. The turbu- lent wave is for small, constricted areas, while the laminar wave removes solder projections. Vapor Phase System — Pr ovides a single-zone condensation heat source achieved with liquid fluorinated hydrocarbons that have been brought to the boiling point to create a saturated vapor zone. Heat is then released by the fluid’s heat of vapor- ization as the vapor condenses on the product. Soldering (Through-hole) Two types of equipment are usually associated with through- hole soldering: Single Wave System — Pr ovides an inclined portion of the solder wave for the PC board to pass over. The PC board is positioned to bring many potential solder joints in contact with the wave simultaneously for a short time for soldering. Drag System — Pr ovides for PC boards to be dragged across the surface of the solder pot. Soldered connections are made during this operation. PC Board Washing Two types of equipment are usually associated with both SMT and through-hole products. Pressure System — Accomplishes cleaning by dir ecting sprays of water under high pressure from multiple nozzles. Flooding System — Utilizes a combination of flooding (at normal water pressure) and surfactant action for cleaning). Soldering and Wash Processes Figure 1 shows typical profiles any component may see during a soldering and board washing operation. For details of materi- al and process variables recommendations, see “Soldering and Cleaning Processes”, page 76. ADJUSTABILITY (OUTPUT VOLTAGE RATIO): The precision with which the output voltage ratio of a device can be set to the desired value. MECHANICAL TERMS STARTING TORQUE: The maximum moment in the clockwise and counterclockwise directions required to initiate shaft adjust- ment anywhere in the mechanical travel. STOP TORQUE: The maximum static moment that can be applied to adjustment shaft at each mechanical stop for a specified period of time without loss of continuity or mechanical damage affecting operational characteristics. SOLDERABILITY: The ability of the terminals to accept a uniform coating of solder under specified conditions. WELDABILITY: The ability of materials to be welded together under specified conditions. TERMINAL STRENGTH: The ability of the terminals to withstand specified mechanical stresses without sustaining damage that would affect utility of the terminals or operation of the trimming potentiometer. IMMERSION SEALED: The ability of the unit to withstand submer- sion in acceptable cleaning solutions used in normal soldering processes without performance degradation under specified environmental conditions. TRIMMER "ABILITIES" When you are selecting components for a new design, you typically take into account the environmental conditions that the components will need to endure during the lifetime of the instrument or device. Designers in the past have often overlooked the environ- mental extremes of their own production lines, where the conditions may be much more severe than anything encountered in actual end use. PROCESSABILITY "Processability" refers to the ability of the unit to withstand the production-line processes associated with the finishing steps on the PC boards. Typically, both SMT and through-hole products are sub- jected to similar PC board processing operations after preparation for assembly. These operations can generally be summarized as follows: Flux Pre-Heat Solderä ä Wash Rinse Dryä ä Applications/Processing Guide Soldering (SMT) Four types of equipment are usually associated with SMT soldering: IR System — Uses a multi-zone infrar ed furnace with IR elements heated to a temperature substantially above chamber or product temperature.

• Pre-heat boards to maximum acceptable level
• Reduce time in solder 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 To limit time of exposure above rated temperature
• Limit time in solder
• 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 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 To minimize exposure to high-pressure water during board wash
• Select trimmer models with pin styles that orient the rotor seal area away from exposure to the high-pressure water stream SETTABILITY 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 incr emental 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).

Environmental factors play an important role here: stability may be affected by temperature exposure, thermal shock/ cycling, humidity, and mechanical shock or vibration. 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. 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.

Specifications are subject to change without notice. 90 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. 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 temperatur e at which the trimmer will operate has an important bearing on power rating. Power ratings are usually specified at 70º or 85ºC; at a temperatur e of 150ºC, the power rating of many trimmers is reduced to zero. Temperature Coefficient of Resistance (T.C.) — This spec ifica- 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 wir ewound models. RELIABILITY 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. SURFACE MOUNTED DEVICES (SMD) AN EMERGING TECHNOLOGY 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).
• Smaller Finished Product Size (addresses demand for miniaturization). Cost, performance, quality/reliability and size — how ar e 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 fr eight 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. 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. GENERAL NOTES: Plated-Through Holes: (Ref.
