... following is a guide to the preferred requirements for producing quality Printed Circuit Boards. Can be supplied as artworks, penplots, photoplots or photoplot files, | MULTILAYER CIRCUIT BOARDS | so long as the quality and registration of the images is of a standard that will enable a good quality board to be produced. Another | MULTILAYER CIRCUIT BOARDS | important criteria is the presence of orientation marks within the boundary of board. These marks could be the board reference so long as it cannot | MULTILAYER CIRCUIT BOARDS | be read from the other side. (This is for your protection to prevent the boards made inside out). Images should comply with design rules that | MULTILAYER CIRCUIT BOARDS | will result in a board that will meet performance and cost requirements. - Scale must be given, tapes securely stuck to the backing sheet, track | MULTILAYER CIRCUIT BOARDS | to pad & track to track joints complete and the backing sheet clean. - Scale must be given and be at least 2:1. Plots must | MULTILAYER CIRCUIT BOARDS | also offer sharp edge definition and traces dense enough for blocking light when photographing. - Preferred on 7mil (178mm) thick base ...

... print and printed solder areas may result. | 10. NON-PLATED HOLES | PRINTED CIRCUIT BOARDS | 10.1 This refers to plated through PCBs: If | MULTILAYER CIRCUIT BOARDS | we do not have any information from you as to which holes are to be plated-through and which are not, we will determine this to | MULTILAYER CIRCUIT BOARDS | the best of our knowledge. 10.2 If non-plated holes are positioned in a pad, this pad must be bigger than the hole by at least | MULTILAYER CIRCUIT BOARDS | factor 1.5. Otherwise some or all of the pads may be removed. | 11. DATA PROVIDED (DATA INCONSISTENCY) | 11.1 If drilling and measurement plans | MULTILAYER CIRCUIT BOARDS | are included that do not match the drilling program or the contour according to the gerber-data, then the drilling program and the gerber-data will be | MULTILAYER CIRCUIT BOARDS | binding in all cases. | 12. PCB CONTOUR | 12.1 If not otherwise stipulated, the PCB contour will be determined by the centre (=centre vector) | MULTILAYER CIRCUIT BOARDS | of the contour lines provided in the order data. If Slots are represented by you by rectangular outlines, then we assume generally that the corner | MULTILAYER CIRCUIT BOARDS | radius is contained. ...
