PCB Assembly Visual Inspection of Welds (SMT)
PCB Assembly Visual Inspection of Welds (SMT)
Defective soldering may directly cause functional defects in products. So, it is very important to inspect solder. Through visual inspection, we can check whether the parameters of the solder paste printer are set correctly, the solder paste of the PCB is printed on the pads and whether the height of the solder paste is consistent or in a “trapezoid” shape. Checking under the microscope whether the solder paste is bright after printing.
