... controlled by an integrator located near the panels.The imaging process is carried out in a controlled environment to minimise the effects of temperature and | PRINTED WIRING BOARDS SHOP | humidity variation and maximise the yield of quality product. After exposure, the panel is ejected from the exposure system and loaded onto an accumulator. Developing | PRINTED WIRING BOARDS SHOP | Image After the panel has been exposed, it is finally developed to remove all areas of unexposed resist. The chemistry in the developer is controlled | PRINTED WIRING BOARDS SHOP | by an automatic replenishment system. This fully automatic system assures consistent and uniform development and eliminates down time for cleaning and replacement of the chemistry. | PRINTED WIRING BOARDS SHOP | The copper tracks and pads thus defined are then ready for the electrolytic plating process or for etching. Remaining resist acts as an etchant barrier. | PRINTED WIRING BOARDS SHOP | Following development, all panels pass through Automatic Optical Inspection (AOI). This inspection stage is to verify that all the design features are in accordance with | PRINTED WIRING BOARDS SHOP | customer ...

... for further processing and continued use. Due to the thin surface layer – a thickness of 0.15 – 0.3 mµ is recommended – the | PRINTED WIRING BOARDS SHOP | surface of the pad is smoother and therefore there are, even in fine pitch areas, no restrictions when assembling. The silver functions merely as a | PRINTED WIRING BOARDS SHOP | protection against oxidation, and the actual solder point is between the copper and chemical tin, therefore the solder point is absolutely stable. It fulfills all | PRINTED WIRING BOARDS SHOP | UL requirements (UL796 specif.) and meets the usual requirements of automobile manufacturers: Test results Test AlphaSTAR Result Requirement SIR 85°C/85%RH 2.46+9 24h Passed >1E+8; IPC- | PRINTED WIRING BOARDS SHOP | 4553 IPC-TM-650 2.6.3.5 3.15E+9 96h Passed SIR 35°C/85%RH 100VDC 3.56E+11 24h Passed >1E+10; IPC-4553 and GR 78 (Bellcore) IPC-TM-650 2.6.3.5 4.62E+11 96h passed EM 10V | PRINTED WIRING BOARDS SHOP | bias, 100V Test 2.46E+9 24h initial Resistance no higher than the Power of 10 85°C/85%RH 1.18E+10 504h (21days) Passed Dendrites not Identified IPC-TM-650 2.6.14.1 Dendrites | PRINTED WIRING BOARDS SHOP | not Identified Passed ...
