Pcb welding quality inspection


1) Visual inspection


Check whether the welding quality is qualified, whether it is leaking, whether there is flux around the solder joint, whether there is continuous welding, bridge welding, whether the pad has cracks, whether the solder joint is smooth, and whether there is a sharpening phenomenon.

2) Hand touch check

Touch the components by hand, whether there is looseness or poor soldering. Use the tweezers to clamp the leads of the components and gently pull them. If there is any looseness, the solder on the solder joints will be peeled off when the soldering points are shaken.
