Pcb Manufacturing Immersion Tin Protection for Printed Circuit Boards (PCBs)

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

... The immersion nickel gold process also requires staff intensive attention as the chemical baths call for a great deal of analysis and supervision due | PCB MANUFACTURING | to the narrow processing slit. The process of solder mask coating as well as deoxidation of bare copper surfaces (activation) must perfectly match the gold | PCB MANUFACTURING | plating. To prevent the risk of poor metallic deposition on the gold surface, vias must be completely free of solder mask coating or be completely | PCB MANUFACTURING | closed by means of a special filling process. Curing of the solder mask coating must also concur with that of the chemical gold plating as | PCB MANUFACTURING | it is exposed to hydrogen in the 90° C nickel baths. One has the choice between an expensive coat-ing system or a subsequent infrared solidification | PCB MANUFACTURING | which, in turn, also calls for further investment in facilities. The potential for a lead-free alternative For a lead free altenative provided the PCB manufacturer | PCB MANUFACTURING | ensures optimal conditions for immersion nickel gold coating, the results of wave ...
