Optoelectronic to welding usually requires micro solder to weld pins and transition blocks. Precision preformed pads ensure solder consistency and narrow space accessibility.
Blue film with weak viscosity is usually used as the feeding means. Through the cooperation of the under film thimble and the suction head, the micro solder is accurately picked up and placed in the area to be welded. The solder is instantly melted by laser or other heat source means to form a stable and reliable melting point
The blue film solder commonly used is composed of Au80Sn20 and sac305
