LASER WELDING MACHINES
High Frequency Nanosecond Fiber Laser Precision Welder-SFM70

High Frequency Nanosecond Fiber Laser Precision Welder-SFM70

– High precision laser welding machine for electronic products, thin metal sheet welding.

– As a nanosecond fiber laser, SFM70 has MOPA configuration with a maximum frequency of 1000 kHz and high peak energy.

– This model is widely applied in thin plate materials welding (below 0.2mm), reflective elements (copper alloy, aluminum alloy, gold) and dissimilar metal welding.

– The solder joints of the products are well formed, uniform in size, and the tensile shear strength are significantly improved compared with YAG and millisecond fiber lasers.

Description
