03. PCB Bent Measurement:

                   a. The standard for PCB Bent
                   According to IPC-A-610D 10.2.7, the maximal sharp change is not allowed to over the
                   0.75% of PCB diagonal length. The gap between PCB and measuring table must be
                   smaller than 4.8mm for RMA standard.

                   b. Why PCB Bent is so important for M/B Repairing?
                   M/B is manufactured with a lot of SMD and DIP components joined to PCB by
                   soldering. If PCB sharp change is over the standard, it would affect the reliability of the
                   soldering and functions.

                   c. The Measuring tool and operation.
