... more cumbersome and difficult for fabricators to deal with because they have to worry about translators and parsers to read the aperture table information. | MULTILAYER CIRCUITS MAKER | As a result, aperture data might be misinterpreted. Worse, someone might have typed in the information manually - and erroneously. By contrast, in 274X, all | MULTILAYER CIRCUITS MAKER | the aperture information is contained within the Gerber file, which can be read by most CAM tools automatically. For netlists, | IPC-D-356 | is the | MULTILAYER CIRCUITS MAKER | preferred format for fabrication. It's widely used by many of the bare-board test-fixturing machines and is one of the only true ways to identify power- | MULTILAYER CIRCUITS MAKER | to-ground shorts. With the information in this format coming directly from the engineering CAD system, there's no danger of the fabricator "reverse engineering" the netlist | MULTILAYER CIRCUITS MAKER | from the Gerber files. Next up are the internal | PLANE LAYERS |. For some reason, CAD engineers like them to be "positive," but those | MULTILAYER CIRCUITS MAKER | types of layers lead to huge file sizes. Negative plane layers are ...

... access the services we offer, the following is a guide to the preferred requirements for producing quality Printed Circuit Boards. Can be supplied as | MULTILAYER CIRCUITS MAKER | artworks, penplots, photoplots or photoplot files, so long as the quality and registration of the images is of a standard that will enable a good | MULTILAYER CIRCUITS MAKER | quality board to be produced. Another important criteria is the presence of orientation marks within the boundary of board. These marks could be the board | MULTILAYER CIRCUITS MAKER | reference so long as it cannot be read from the other side. (This is for your protection to prevent the boards made inside out). Images | MULTILAYER CIRCUITS MAKER | should comply with design rules that will result in a board that will meet performance and cost requirements. - Scale must be given, tapes securely | MULTILAYER CIRCUITS MAKER | stuck to the backing sheet, track to pad & track to track joints complete and the backing sheet clean. - Scale must be given and | MULTILAYER CIRCUITS MAKER | be at least 2:1. Plots must also offer sharp edge definition and traces dense enough for blocking light when photographing. - ...
