SMT PCB Assembly Inspection Necessity
In order to ensure the quality and performance of the assembled PCB, it is very necessary to check during the entire SMT assembly process. Multiple types of inspections must be used to reveal manufacturing defects, which can reduce the reliability of the final product.
Visual inspection is most commonly used in SMT patch assembly. As a direct inspection method, visual inspection can be used to indicate obvious physical errors, such as component displacement, missing components, or component irregularity.
Visual inspection is not suitable for visual inspection. Tools such as a magnifying glass or microscope can also be used. In order to further point out the defects occurring in the welding ball, AOI and X-ray inspection can be used after the completion of coal bonding
