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

... out of the gerber data of the customer. As a middle and high volume manufacturer we use an adapter testing system that simultaneously tests | PRINTED WIRING BOARDS PRODUCTION | all network lines and points of a PCB. The basic technology of adapter testing is, that conductive needles linked to the test machine are lead | PRINTED WIRING BOARDS PRODUCTION | by an adapter to the test points of the PCB. The test result is then compared to the electrical network. A failure is detected if | PRINTED WIRING BOARDS PRODUCTION | a network resistance is measured * bigger than 50 Ohm (cut) * smaller 10 MOhm (short) PCB`s tested without failure are marked by a green | PRINTED WIRING BOARDS PRODUCTION | line on the edge of the PCB or by a stamp mark. Rejected PCB`s are separated, repaired and retested or finally rejected if repair is | PRINTED WIRING BOARDS PRODUCTION | not feasible. The electrical test is not standard but we recommend it to the customer if the following features are given: * high circuit complexity | PRINTED WIRING BOARDS PRODUCTION | * trace/gap smaller 200µ * embedding circuits in ground layers (thieving) * Multilayer Boards Although we assist our clients in the decision finding, it`s up | PRINTED WIRING BOARDS PRODUCTION | to ...

... spacing Identify potential drill problems. Validate soldermask layers. First off, make sure layers are properly aligned and ordered correctly. File names should be meaningful, | PRINTED WIRING BOARDS PRODUCTION | correlated with the layers, and explained to the fabricator in a | README FILE |. The idea here is that the fabricator should be able | PRINTED WIRING BOARDS PRODUCTION | to quickly understand what each file is and where it goes in the stackup. If you wish to continue using Gerber data | PRINTED CIRCUIT | PRINTED WIRING BOARDS PRODUCTION | BOARDS | , switch to 274X. 274D is obsolete; the external aperture information is more cumbersome and difficult for fabricators to deal with because they | PRINTED WIRING BOARDS PRODUCTION | have to worry about translators and parsers to read the aperture table information. As a result, aperture data might be misinterpreted. Worse, someone might have | PRINTED WIRING BOARDS PRODUCTION | typed in the information manually - and erroneously. By contrast, in 274X, all the aperture information is contained within the Gerber file, which can be | PRINTED WIRING BOARDS PRODUCTION | read by most CAM tools automatically. | FOR NETLISTS |, IPC-D-356 is the preferred ...
