How to judge the quality of solder joints on CBA board?
Pcba boards are generally inspected in SMT factories in accordance with ipC-A-610 standards. Since there are many types of solder joints, it is difficult to describe them simply. Therefore, we decompose solder joints into multiple dimensions and evaluate them with a single requirement. It's a way of dealing with complex problems, and it's worth learning.Printed Circuit Board (PCB) is the abbreviation of SMT, which is a series of processes based on PCB. SMT is the abbreviation of Surface Mounted Technology (Surface Mounted Technology), which is one of the most popular technologies and processes in the electronic assembly industry.
Generally, the SMT(SMD) process is completed by reflow welding, and the DIP is usually completed by wave soldering or full automatic dipping machine.
