... The Dilemma is obvious: The days of the first “printed circuits” which could be checked simply with the naked eye are over. Today, high-tech | PCB PRODUCE | equipment is necessary for a thorough PCB test. Optical checks with the aid of conventional micro-scopic equipment are sufficient for one sided and relatively simple | PCB PRODUCE | double-sided PCBs. Residues, constricted conductors and subcorrosions can be discovered which would otherwise lead to PCB failure after a number of operational hours. An electrical | PCB PRODUCE | test is needed to check the actual functions of a PCB. It is an essential if inner layers need to be tested, as is the | PCB PRODUCE | case with multi-layers. In two position measure-ments all connections in the PCB are checked for stoppages and short circuits. All SMD pads and plated through | PCB PRODUCE | holes are checked. The electrical test can be conducted as a parallel or finger test. Parallel test: For the parallel test a control adaptor is | PCB PRODUCE | constructed, consisting, e.g. of several synthetic sheets positioned above each ...

... must be supplied with each new job and should contain the following information to ensure that the finished board is to your requirements. - | PCB PRODUCE | Always required even when a drill file is supplied, to enable inspection of panels immediately after drilling and finished boards prior to despatching. Hole sizes | PCB PRODUCE | must be clearly represented with distinct differences between each size. Tolerances are not required unless different to our standard of +0.1 / -0.05 mm. - | PCB PRODUCE | Preferred with overall mechanical dimensions including notches, cutouts and slots. Also preferred is a positioning (datum) dimension (drilled hole is best). Tolerances are not required | PCB PRODUCE | unless different to our standard of + / -0.25 mm. Other information required for all boards includes: board thickness (standard = 1.6mm) base copper thickness | PCB PRODUCE | (std = 18mm) solder mask colour (std = green) solder mask type (std = liquid photoimageable) component legend colour (std = white) bare board testing | PCB PRODUCE | requirement (std for multilayer and ...
