Tehnična načela laserskega spajljenja
Laser soldering uses a high-energy laser beam to focus on the solder ball and the welding part, generating high heat instantly and melting the solder ball quickly. The high energy density of the laser concentrates the heat and the heat-affected area is small. At the same time, the precise positioning and energy controllability of the laser ensure accurate welding position and stable welding quality, Doseganje pri povezavi z visoko natančnostjo .
Proces spajkanja
Lasersko spajkanje je metoda povezovanja materialov z uporabo laserja kot vira toplote, ki deluje na območju spajkanja, segreva spajkalna sklepe, topi kositer in tvori plast IMC na površini spajskega sklepa .
