Printed circuit board manufacture request ========================================= Name Ronja Twister2 revision 20060405 Construction class 4 Shape Rectangle with beveled corners, middle of the outline drawn in twister2.pcb.output_fab.gbr Width 3162.00 mil (80.315 mm) Height 5416.00 mil (137.541 mm) Layer file format Gerber RS 274X Drill data format Excellon Drill data meaning Final diameter of hole Rounding hole Round toward bigger diameter diameters Layers Two-layer through-plated, 2x soldermask, 2x silkscreen Material FR4 Material thickness 1.2mm Copper thickness of basic material 35um or more Chirality All layers are presented as if viewed from one side (component side). Copper polarity Positive. Dark places in file mean copper. Soldermask polarity Negative. Clear spaces in file mean mask matter. Silkscreen polarity Positive. Dark places in file mean paint Through-plating All holes are through-plated Gold-plating None Surface treatment Hot Air Levelling Edge treatment Milling Testing Optical if at least 3 pieces are manufactured Note: Gerber RS274 format means "Gerber RS-274X Format", defined in the year1998 by the company Barco Graphics N.V., Gent, Belgium (Barco ETS, Tramstraat 69, B-9052 Gent, etsinfo@barco.com), see http://nexp.cs.pdx.edu/twiki-gerber/pub/Gerber/GerberFiles/rs274xrevd_e.pdf File meaning ============ twister2.pcb.output_back.gbr Solder side - copper twister2.pcb.output_backmask.gbr Solder side - soldermask twister2.pcb.output_backsilk.gbr Solder side - silkscreen twister2.pcb.output_fab.gbr Drilling checkplan twister2.pcb.output_front.gbr Component side - copper twister2.pcb.output_frontmask.gbr Component side - soldermask twister2.pcb.output_frontsilk.gbr Component side - silkscreen twister2.pcb.output_plated-drill.cnc Drill data - throughplated holes Previews -------- Views are in PostScript format and have only informal meaning to check that the data have been interpreted correctly.
