... conducted as a parallel or finger test. Parallel test: For the parallel test a control adaptor is constructed, consisting, e.g. of several synthetic sheets | PRINTED WIRING BOARDS TECHNOLOGIES | positioned above each other and fitted with control pins. An adaptor programme must be written to reflect the actual holes in each individual synthetic layer | PRINTED WIRING BOARDS TECHNOLOGIES | of the adaptor. The pin positions are identical to the control points enabling an overall PCB test within seconds. The control adaptors are all the | PRINTED WIRING BOARDS TECHNOLOGIES | more expensive the higher the density and the lower the grid distances between control points. The adaptors can also only be used for one specific | PRINTED WIRING BOARDS TECHNOLOGIES | type of PCB which explains the high set-up costs for the test. Finger Test: As PCB series are not always produced in mass, the finger | PRINTED WIRING BOARDS TECHNOLOGIES | test was developed as an alternative solution for small or medium-sized series. Manoeuverable probes move to the control points without necessitating an adaptor. As the | PRINTED WIRING BOARDS TECHNOLOGIES | points are checked individually, the time required for a complete check depends on ...
