This catalogue describes the extended range we offer in this format on both, thick film carbon and cermet technologies. The majority of the standard and special features that the traditional THT (Through Hole Technology) series offers can be supplied also in SMD format. The potentiometers can be packed either in bulk, or Tape-n-Reel for automated assembly onto the PCB. In addition to the SMD range, THT Pin in Paste options can also be available under demand, with the possibility to be Tape-n-Reel packed. We welcome you to go through this catalogue to select the most adequate option to suit your needs. Please, contact our sales and technical support network for any assistance. If you do not find what you want, remember that we are specialized in building custom solutions. Carbon and cermet technologies ACP SMD potentiometers, like the traditional THT mount, can be manufactured using two different thick film technologies regarding the resistive element: carbon (6, 9 and mm sizes) and cermet (9 and mm sizes). Cermet is more robust and is recommended in high temperature and high power dissipation requirements. The nature of the resistive element and the plastic and metal materials, used in their configuration, are sturdy enough to go through the reflow process with no risk to get damaged. For less demanding environment and power dissipation requirements, carbon element is the most common used technology. It is a very cost effective product, but on the other hand it is more sensitive to the reflow heat stress. Here is where our engineers propose materials and processes to make a carbon based potentiometer suitable for SMD. Specifications on this catalog are for reference only, as they are subject to change without notice.

4 Reflow soldering The first challenge that SMD potentiometers must overcome is the reflow soldering profile. Like every other component in this format, potentiometers must be able to withstand the severe heat stress experienced during that process. Our engineers have selected the most adequate metals, plastics and resistive elements to make sure that after that process the electrical and mechanical properties are kept to secure proper functioning in the application. A compromise must always be found in order to secure good functional performance and good solder joints. Solder profiles are set by customer depending on the PCB layout and component density. To avoid damaging the components there are limits that every manufacturer establishes based on studies and tests. At ACP, we feature the SMD potentiometers according to the European Standard EN Based on the results obtained, we propose our recommended soldering profiles. ACP recommended profiles Over 0ºC: <0 s Peak Temp: 0ºC; 5 s 0 00 Carbon Potentiometers Temperature (ºC) Ramp-up: - ºC s Preheat: Max. 0ºC-60 ºC; s Seconds Over 0ºC: <60 s Peak Temp: 50ºC; s Cermet potentiometers Temperature (ºC) Preheat: Max. 50 ºC -80 ºC; 60- s Ramp-up: - ºC s Seconds Pre-heating Heating (above liquidous) Peak Temp (ºC) Time (sec) Temp (ºC) Time (sec) Temp (ºC) max. Time(sec) CA CE Over 0 Over 0 <0 < Value shift after reflow The nature of polymer thick film (carbon) resistive elements is such that they are sensitive to temperatures above 50ºC. In their manufacturing process the inks deposited on the different substrates are cured at high temperatures for a certain period of time in order to polymerize them and obtain a stabilized value. You can imagine that submitting them during the reflow soldering process to temperatures of 0ºC and higher, even for a few seconds, is a heat stress that may modify the polymer structure and originate a value shift. The value change that a carbon potentiometer may experience depends on the resistive value. This has a consequence, tight resistive tolerances on carbon potentiometers will suffer a shift that may result in real resistive values beyond the limits. This effect is only present on the carbon resistive elements. Cermet Thick film based resistive tracks are very stable and the reflow process does not affect them at all, there are no value changes after that.

10 Detents silver zones ACP s patented detent (DT) feature is especially suitable for control applications where the end user will turn a knob inserted in the potentiometer. Detents add a click feeling to the turning of the potentiometer and a control of the angle position of the wiper, assuring a particular output value. The standard configuration is an even distribution of the detents along the mechanical angle. Hence, the output value obtained in each detent is proportional to the angle turned from the initial position, within the tolerance limits of the corresponding taper: linear, log, antilog, cut track or special. Our patented design with two wipers has improved the performance of these potentiometers, giving them more stable electrical parameters, improved reliability and Contact Resistance Variation (CRV) and narrower tolerances for detent positioning. Detents can be light or strong, or even a combination of different feelings is possible. Applications of the detents are, ) just to provide a haptic click feeling along the travel of the potentiometer or ) in addition to that, to secure a non-overlapping output of contiguous positions. The table below describes the maximum number of detents offered for both options. One common example is a potentiometer with detents and matching non-overlapping voltage values in specific angular positions used to feed in a voltage value to a microcontroller.
