SMT BGA solder ball inspection method- Know about cost
Original: SMT BGA solder ball inspection method - Know about cost Usually, when we check the soldering status of BGA solder balls, we can usually check them with X-ray inspection machine If we want to check if the solder balls lack solder or cracks/weld bridge/short defects. BGA solder ball inspection Basically ,There are three ways to check the solderability of BGA, using X-rays, Red Dye Penetration Test and slicing. Before you want to analyze the welding status of the BGA, it is recommended that you use X-ray machine to see if you can see any problems. The other two methods continue to be used only when X-Ray is unable to determine the problem. There is also a way to use optical instruments to inspect BGA solder balls, such as microscopes or fiber optic miniature cameras, but since the BGA spacing is getting smaller, it usually only checks the two rows of BGAs. Tin ball, another is a bit difficult, so we won’t introduce it here. In fact, there is als...
