The two major process technologies in PCB assembly include surface mount technology and through-hole technology, which will use reflow soldering technology and wave soldering technology, respectively. With the development of assembly technology and the need for practical applications, selective wave soldering is also increasingly popular.
There are many welding methods in the PCB assembly process. This article will introduce 5 welding processes that may be encountered in the PCB assembly process in detail.
The common rule for soldering on flex PCBs is this: Don’t use the temperature profile for conventional PCBs to solder flex PCBs.
Soldering is an essential process in PCBA manufacturing because it connects the components to the board. Wave soldering and reflow soldering are the commonly used soldering processes in the industry.
