... work is completed, step into the fabrication | PRINTED CIRCUIT BOARDS | analysis arena, where the game is one of checks and balances. You've | PRINTED WIRING BOARDS MANUFACTURING | got your design rules; fabricators have theirs. Checks and balances can resolve any conflicts between the two. | TAKE SOLDERMASK LAYERS |, for instance. Often, | PRINTED WIRING BOARDS MANUFACTURING | these layers are not "intelligent" layers within a CAD tool; that is, there is not much in the way of capability checking within the tool. | PRINTED WIRING BOARDS MANUFACTURING | As a result, these are among the more troublesome layers for fabricators. The solution here is a fabrication analysis tool that can handle such issues | PRINTED WIRING BOARDS MANUFACTURING | as clearances, coverage, webbing, and so forth. For instance, most fab shops want the largest possible | CLEARANCES | in a solder layer so that | PRINTED WIRING BOARDS MANUFACTURING | mask doesn't end up on pads. On the flip side, copper is not supposed to be exposed. The two requirements - no mask on pads | PRINTED WIRING BOARDS MANUFACTURING | and unwanted exposed copper - must be balanced. It is not easy to do. How can the designer help? Devise a standardized clearance, or ...

... | 11. DATA PROVIDED (DATA INCONSISTENCY) | 11.1 If drilling and measurement plans are included that do not match the drilling program or the | PRINTED WIRING BOARDS MANUFACTURING | contour according to the gerber-data, then the drilling program and the gerber-data will be binding in all cases. | 12. PCB CONTOUR | 12.1 If | PRINTED WIRING BOARDS MANUFACTURING | not otherwise stipulated, the PCB contour will be determined by the centre (=centre vector) of the contour lines provided in the order data. If Slots | PRINTED WIRING BOARDS MANUFACTURING | are represented by you by rectangular outlines, then we assume generally that the corner radius is contained. | 13. TECHNICAL SPECIFICATIONS | PRINTED CIRCUIT BOARDS | PRINTED WIRING BOARDS MANUFACTURING | | 13.1 For further technical specifications of our manufacturing processes, please refer to our Process & Capability Manual in the "Standard" category. These standard technical | PRINTED WIRING BOARDS MANUFACTURING | criteria also apply even if your manufacturing data and documents call for other features (special technical requirements are available in our Premium Jet Line). | | PRINTED WIRING BOARDS MANUFACTURING | 14.
