The pogo pin is an electronic component with elastic contact, which has three parts: plunger, spring, barrel. The barrel is generally used as a fixed part and is combined with other materials through various processes to form a channel for current or signal transmission. Pogo pins have a wide range of applications. For example, TWS/OWS headsets, tablets, hearing aids, handheld devices and other products. When applying pogo pins to different products, we usually need to combine the product’s internal structural design analysis and adopt different assembly methods.

Pogo pin assembly and connection methods generally include welding wires, PCB board welding, or elastic butt assembly. PCB board welding (SMT process) is the most commonly used method at present. Because of its obvious advantages such as automated production, large-scale production, and high efficiency. Moreover, the quality is stable and the product space is compact, which is in line with the current development trend of electronic products. SMT (Surface Mounted Technology) technology is also divided into two processes: reflow soldering and wave soldering.

The main things to pay attention to in PCB welding are the flatness and dimensional accuracy of the product. Because the welding machine automatically picks up and places materials. If the bottom of the product is uneven or the size is inaccurate, placing it on the board may cause the product to deflect, skew, etc., affecting the welding quality.For welding wires, the spring pins are usually fixed first and then assembled on the plastic parts or PCB. The wire is soldered to the end of the PCB.

What you need to pay attention to when wire welding is the welding time or temperature. Generally, welding wires use high-temperature solder, which will heat up the plastic parts over time, causing them to melt. As a result, the spring needle cannot be fixed on the plastic part, and there is a risk of the needle withdrawing. For products that are generally small in size or high in density, we usually solder the PCB to transfer the bonding wires. In this way, the welding temperature will not be directly transmitted to the plastic parts and will not affect the assembly of spring pins and plastics.
