... Optical Inspection) of Inner Layer All inner layers then pass through Automatic Optical Inspection (AOI). This inspection stage is to verify that all the | PRINTED WIRING BOARDS PRODUCE | design features are in accordance with customer requirements. The final stage of inner layer manufacture is to punch tooling holes into the layers to achieve | PRINTED WIRING BOARDS PRODUCE | good layer-to-layer registration in the bonding process. Final QC-Inspection-Department + zoom + Optical Tester - Opens and Shorts (narrow and wide) - Conductor and Spacing | PRINTED WIRING BOARDS PRODUCE | Width vialations - Nicks, Pinholes and Extraneous Metal - Missing, defective or misregistered pads - Shorts and potential shorts in power and ground clearances. - | PRINTED WIRING BOARDS PRODUCE | Three conductor widths, minimum and maximum width violations - Annular ring width violations with or without breakout allowed. - Missing or plugged holes - Average | PRINTED WIRING BOARDS PRODUCE | line width measurements for controlled impedance panels - Dimensional distortions - Missing traces and ...

... adhesion of both plating and resist. OSP Organic Solderability Preservative (alternativ) This is a further alternative to the hot air levelled solder and electroless | PRINTED WIRING BOARDS PRODUCE | nickel / immersion gold finishes. It is an organic solderability preservative (OSP) and is normally applied after the screen printing and profiling stages of manufacture. | PRINTED WIRING BOARDS PRODUCE | Boards to be treated are chemically etched, cleaned and dried before being passed through a flood rinse module containing the OSP solution. This solution reacts | PRINTED WIRING BOARDS PRODUCE | chemically with the clean copper to form a thin layer of an organic complex some 0.3 microns thick. Results are monitored on a regular basis | PRINTED WIRING BOARDS PRODUCE | by coating test panels and assessing the thickness achieved by UV spectrometric means. Following treatment, the boards are rinsed to remove residues and dried to | PRINTED WIRING BOARDS PRODUCE | obtain a uniform film. Further drying completes the curing of the film, which then protects the underlying copper from environmental influences and subsequent multipass processing | PRINTED WIRING BOARDS PRODUCE | by the ...
