... of our work and the measures to be taken are determined by the conscience to meet our customer`s needs. Quality concerns everybody in our | PCB | company. Our executive staff must show an exemplary and leading behaviour in every aspect of quality. Development and promotion of fault avoiding working spirit. A | PCB | cooperative management style is the first condition for involving our employees in the process of solving problems. | MISSION STATEMENT | (Aims and strategies in | PCB | our policy of quality) "We are dedicated to total customer satisfaction through continuous improvement in quality, technology and cycle times. (For us quality is the | PCB | creation of a product that meets our customer`s requirements at 100 percent. This means precisely not only to guarantee the physical and functional attributes of | PCB | a product but also every aspect of service linked to the ...

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

... To prevent the risk of poor metallic deposition on the gold surface, vias must be completely free of solder mask coating or be completely closed | PCB | by means of a special filling process. Curing of the solder mask coating must also concur with that of the chemical gold plating as it | PCB | is exposed to hydrogen in the 90° C nickel baths. One has the choice between an expensive coating system or a subsequent infrared solidification which, | PCB | in turn, also calls for further investment in facilities. THE POTENTIAL For a lead free altenative provided the PCB manufacturer ensures optimal conditions for immersion | PCB | nickel gold coating, the results of wave soldering are equally good to solder levelling. Good storage ability is also achieved by covering the pad and | PCB | smd sides with gold. In our opinion, however, immersion nickel / gold will never become an established alternative to HAL. As already mentioned, the processing | PCB | costs are the greatest handicap for this method. However, due to the lack of other ...
