Qixing Electronics BONENS 3323 Potentiometer Soldering Tips: Controlling Soldering Temperature and Time for Nickel Terminals

In response to the soldering characteristics of the nickel terminals on the BONENS 3323 potentiometer, Qixing Electronics recently released a specialized soldering guide that places particular emphasis on the precise control of soldering temperature and time. This guide is designed to help users avoid product damage caused by improper soldering practices, thereby improving both soldering quality and efficiency. The guide clearly specifies that the soldering of the nickel terminals on the BONENS 3323 requires strict control of both temperature and time: For wave soldering, the recommended soldering temperature is 260 ± 5℃, with a soldering duration of 3 to 5 seconds; for reflow soldering, the peak soldering temperature should not exceed 260℃, and the duration at high temperature should be no more than 10 seconds. If the soldering temperature is too high or the soldering time is too long, it may lead to oxidation and deformation of the nickel terminals, and even damage to the internal resistive element. Conversely, if the temperature is too low or the soldering time is too short, issues such as cold solder joints or false soldering may occur, compromising the reliability of circuit connections. In addition, the guide provides practical tips: Before soldering, ensure that the PCB board pads are clean and free of oil, grease, or oxide layers; during soldering, avoid excessive residual flux to prevent corrosion of the terminals; after soldering, allow the product to cool naturally to room temperature before proceeding with subsequent operations, thus avoiding deformation of the terminals caused by contact at high temperatures. According to Qixing Electronics’ technical support engineers, nickel terminals boast excellent conductivity and corrosion resistance, but their soldering process demands a high level of precision. By following scientifically sound soldering techniques, users can fully harness the product’s performance advantages. Currently, this guide has been widely disseminated among partner customers through online training sessions and technical manuals, effectively boosting their soldering qualification rates.
