... | Quality - Management - Guidelinses Tolerances may not longer be instruments of the legalization of comfort results. Tolerances must be regarded rather as | MULTILAYER CIRCUIT BOARDS FABRICATORS | unwanted function loss, which have to avoid or to limit. | IN ORDER TO ACHIEVE THIS GOAL |, not only the control of the own | MULTILAYER CIRCUIT BOARDS FABRICATORS | production processes is necessary, also as a starting point of the manufacturing is the procurement of qualitatively perfect products of our suppliers. Therefore obligate our | MULTILAYER CIRCUIT BOARDS FABRICATORS | suppliers to be able to manufacture in application of our consistent quality philosophy and in definition of methodology and realization provably the correct quality. For | MULTILAYER CIRCUIT BOARDS FABRICATORS | this among other things counts the obligation of our suppliers to attach to each supply a test certificate. This demand is a component of our | MULTILAYER CIRCUIT BOARDS FABRICATORS | quality management system and we evaluate and control it continuously with an evaluation procedure. Beyond that the examinations are regulated in our house by employment | MULTILAYER CIRCUIT BOARDS FABRICATORS | regulations in the inspection of incoming goods. - In ...

... board fabrication process. Run a series of checks and balances that help prepare the data set before sending it. Automated software is available to | MULTILAYER CIRCUIT BOARDS FABRICATORS | assist in this process, and all designers should at least do the following: Document layers and file names Check spacing Take advantage of 274X Identify | MULTILAYER CIRCUIT BOARDS FABRICATORS | potential drill problems Include IPC-D-356 netlist data Validate soldermask layers First off, make sure layers are properly aligned and ordered correctly. File names should be | MULTILAYER CIRCUIT BOARDS FABRICATORS | meaningful, correlated with the layers, and explained to the fabricator in a README file. The idea here is that the fabricator should be able to | MULTILAYER CIRCUIT BOARDS FABRICATORS | quickly understand what each file is and where it goes in the stackup. If you wish to continue using Gerber data, switch to 274X. 274D | MULTILAYER CIRCUIT BOARDS FABRICATORS | is obsolete; the external aperture information is more cumbersome and difficult for fabricators to deal with because they have to worry about translators and parsers | MULTILAYER CIRCUIT BOARDS FABRICATORS | to read the aperture table information. As a result, aperture data ...

... Immersion nickel gold process has long been an established surface refining process among printed circuit board techniques. However, in spite of many advantages over | MULTILAYER CIRCUIT BOARDS FABRICATORS | conventional solder levelling it has only been adopted for certain application areas. Nickel gold is utilized in particular where PCB surfaces are exposed to aggressive | MULTILAYER CIRCUIT BOARDS FABRICATORS | environments, for instance in mobile phones, or automobile electronics. Due to the consistent chemical precipitation of metal, gold is the obvious choice for all fine-pitch | MULTILAYER CIRCUIT BOARDS FABRICATORS | assemblings with under 0,5 mm grid spaces. Due to its smooth excellence, the immersion nickel gold surface is a better alternative to HAL, particularly for | MULTILAYER CIRCUIT BOARDS FABRICATORS | narrow SMD grids on both side of PCB`s. The actual wiring of a component is effected by means of a 4-6 my thick layer of | MULTILAYER CIRCUIT BOARDS FABRICATORS | nickel, and not by means of the extremely fine 0,05 to 0,2 my layer of gold which merely serves as an oxidation and diffusion blockage | MULTILAYER CIRCUIT BOARDS FABRICATORS | in order to extend the soldering conditions. Thicker gold layers, up to ...
