Appearance acceptance of PCB assembly products

Visual inspection of the PCBA assembly circuit board is an essential step. This includes checking the appearance of the circuit board to confirm that there is no obvious physical damage, such as cracks, scratches, or damage to the solder mask layer. At the same time, it is necessary to carefully inspect the quality of welding to ensure that the welding points are smooth, full, and free from false welding, empty welding, or missed welding. In addition, the installation position of the components also needs to be checked to ensure that there is no tilt, offset, or misalignment.
