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

Also called OS. | FINAL COPPER THICKNESS | The copper thickness stated in | PRINTED CIRCUIT BOARDS PROTOTYPE | the PCB specification. This thickness is to be understood as the total thickness of copper foil + copper plating. Fine-pitch SMD component with center-to-center terminal | PRINTED CIRCUIT BOARDS PROTOTYPE | distances of less than 0,635 mm. Fluxing The process of removing oxides from a PCB to prepare it for soldering. Fluxing lowers the surface tension | PRINTED CIRCUIT BOARDS PROTOTYPE | of the solder and helps promote the formation of good solder fillets. Foil A thin continuous sheet of metal, usually copper or aluminum, used as | PRINTED CIRCUIT BOARDS PROTOTYPE | the conductor for printed circuits. Foils used for printed circuits are commonly 1 or 2 ounces per square foot the thinner the foil, the lower | PRINTED CIRCUIT BOARDS PROTOTYPE | the required etch time. Thinner foils also permit finer definition and spacing. See Copper Foil. | FULLY ADDITIVE PROCESS |An additive process wherein the entire | PRINTED CIRCUIT BOARDS PROTOTYPE | thickness of electrically isolated conductors is built up by electroless metal ...

An adaptor programme | PRINTED CIRCUIT BOARDS PROTOTYPE | must be written to reflect the actual holes in each individual synthetic layer of the adaptor. The pin positions are identical to the control points | PRINTED CIRCUIT BOARDS PROTOTYPE | enabling an overall PCB test within seconds. The control adaptors are all the more expensive the higher the density and the lower the grid distances | PRINTED CIRCUIT BOARDS PROTOTYPE | between control points. The adaptors can also only be used for one specific type of PCB which explains the high set-up costs for the test. | PRINTED CIRCUIT BOARDS PROTOTYPE | Finger Test: As PCB series are not always produced in mass, the finger test was developed as an alternative solution for small or medium-sized series. | PRINTED CIRCUIT BOARDS PROTOTYPE | Manoeuverable probes move to the control points without necessitating an adaptor. As the points are checked individually, the time required for a complete check depends | PRINTED CIRCUIT BOARDS PROTOTYPE | on the number of control points. In extremely complex layouts the ...
