FPC supplier：What is FPC inspection
In short, FPC supplier’s inspection is the act of mitigating errors or mistakes that may have emerged during the fabrication and assembly processes. This is done through a series of procedures that have largely become automated.
FPC inspection is required throughout multiple stages of the assembly process. After a printed circuit board has been fabricated, an inspection is done to seek out any shorts or defects that might be present before shipping. A second inspection occurs after FPC assembly components have been attached to the board.
The IPC has set guidelines for what constitutes an acceptable board. The IPC-A-610 inspection standard is used for assembly inspection, while the IPC-A-600 is used for bare board inspection.
Depending on the class of circuit board being produced, more stringent rules around testing must be followed. Class 3 printed circuit boards, the same used in commercial jets, space shuttles, and high temperature FPC environments, have no margin for error, and thus have the highest inspection frequency.
