PCB through-hole insertion service

At present, PCBA through-hole welding is the most widely used wave soldering process, also referred to as PTH and DIP. PTH is the abbreviation of Plate Through Hole, which is mostly used in European and American enterprises, meaning plate through-hole process. The other is called DIP, which originates from the fact that the part feet are immersed in the tin wave in the wave soldering process to achieve the purpose of welding. It is used in Japanese enterprises, and the industry believes that DIP=PTH.

Wave soldering is a very critical process in our production and assembly process, such as the common double-sided mixed plate.

With the development of electronic products towards miniaturization, multi-function and high performance, PCB assembly has also developed into surface mount (SMT) based assembly. However, due to the constraints of inherent strength, reliability, applicability and other factors of the product, a certain number of through-hole plug-in components will still be used in the product. The current assembly process is usually to manually assemble through-hole components after reflow soldering to complete the assembly of printed boards.

Automatic plug-in（AI）

Automatic plug-in technology (automatic insertion) is a part of through-hole installation technology, which uses an automatic plug-in device to insert electronic components into the through-hole of a printed circuit board. The installation density is increased, the reliability and anti vibration are improved, and the frequency characteristics are improved. Improve the degree of automation and labor efficiency, and reduce costs.

Wave soldering

Wave soldering is to use wave soldering machine to complete all solder joints of circuit board through-hole at one time The main structure is a tin melting cylinder with automatic temperature control, which is equipped with a mechanical pump and a nozzle with special structure The mechanical pump can continuously press out the liquid tin wave from the nozzle according to the welding requirements. When the printed board enters from the conveyor at a certain speed, the soldering tin continuously overflows to the printed board surface in the form of wave peaks for welding. Its operation process is: preparation before welding → flux coating → preheating → wave soldering → cooling.
