... a control adaptor is constructed, consisting, e.g. of several synthetic sheets positioned above each other and fitted with control pins. An adaptor programme must | CIRCUIT BOARDS PLANT | be written to reflect the actual holes in each individual synthetic layer of the adaptor. The pin positions are identical to the control points enabling | CIRCUIT BOARDS PLANT | an overall PCB test within seconds. The control adaptors are all the more expensive the higher the density and the lower the grid distances between | CIRCUIT BOARDS PLANT | 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. Finger | CIRCUIT BOARDS PLANT | 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. Manoeuverable | CIRCUIT BOARDS PLANT | probes move to the control points without necessitating an adaptor. As the points are checked individually, the time required for a complete check depends on | CIRCUIT BOARDS PLANT | the number of control points. In extremely complex layouts the test can take ...

Can be supplied as artworks, penplots, photoplots or photoplot files, so long as the | CIRCUIT BOARDS PLANT | quality and registration of the images is of a standard that will enable a good quality board to be produced. Another important criteria is the | CIRCUIT BOARDS PLANT | presence of orientation marks within the boundary of board. These marks could be the board reference so long as it cannot be read from the | CIRCUIT BOARDS PLANT | other side. (This is for your protection to prevent the boards made inside out). Images should comply with design rules that will result in a | CIRCUIT BOARDS PLANT | board that will meet performance and cost requirements. ARTWORKS Scale must be given, tapes securely stuck to the backing sheet, track to pad & track | CIRCUIT BOARDS PLANT | to track joints complete and the backing sheet clean. PENPLOTS Scale must be given and be at least ...

The PCBs must be at least 6,00 mm apart. | WE ADOPT YOUR DATA | CIRCUIT BOARDS PLANT | WITHOUT | any further examination, according to the motto: "What you see is what you get". The Multi-Panel-System (MP) is available in sizes up to | CIRCUIT BOARDS PLANT | 490mm x 290mm maximum, whereby the individual PCBs with milling fixing tabs of 1.5mm must be kept below this size. | THE MILLING GROOVE | | CIRCUIT BOARDS PLANT | for the outer contour is 2.4 mm. The boards are milled in accor-dance with the dimensionlayer, which must be a separate layer containing just the | CIRCUIT BOARDS PLANT | unbroken contour of the boards (edge markings or drawings are not suitable and result in additional charge). | SELECTED CAPABILITIES: | Archiving Process Data Drill- | CIRCUIT BOARDS PLANT | / Milling Program Archiving Customer Data Production Data Conversion E-Test optional Design Check UL - approval Design Adjustment Further Options | TECHNICAL SPECIFICATION: | "Delivery: | CIRCUIT BOARDS PLANT | Multi-Panel (MP): Delivery-Size of the Panelized Board Array is 490 mm x 290 mm with Fixing Tabs by ...
