Han's Laser Solder Ball Welding System - Wafer Pre-Soldering Machine Solder ball welding refers to a soldering method where solder balls are used as additional solder material. The laser acts on the solder balls, and the molten solder is sprayed onto the joint surface through protective gas. Since the solder balls do not contain flux, there will be no splashing after laser heating and melting, and the amount of solder is constant. The solder ball welding process is fast and precise, making it pa

Design for Manufacture Considerations for Ball Grid Array (BGA) Packages The miniaturization of electronics is widely attributed to advances in semiconductor technology as observed by Moore’s Law, but many overlook the design and manufacturing challenges involved in utilizing small device packages such as ball grid arrays.
