Sampling size: length × width = 5*5~50*50mm (customizable) Maximum size of the whole board to be taken: 610*700mm (can be taken to any position of the PCB board) Precision high-speed spindle: 30000r/min, 2000w, AC200V/50Hz/5A Sampling machine gong: 1/8〞 (freely replace the gong, 2.0mm is recommended) Sampling method: upper gong sampling method Air source pressure: 0.6-0.8Mpa Laser light source positioning: cross line. The feeding method is pneumatic descent, the sampling dust can be absorbed by the vacuum cleaner, and the machine stops automatically after sampling.
