9. Defects in soldered joints
As with any assembly process, defects may occur in the brazed joint, and these are listed in the international standard NF EN ISO 18279 for brazing, the standard IPC-A-610-H groups together the acceptability criteria for electronic assemblies. Defects include any anomaly in the soldered joint, or any deviation from the initial positioning or final shape to be obtained.
The main internal and external defects to remember are in this non-exhaustive list:
