The board with chips in BGA packages, require very small copper width and space. Some manufacturer provide different minimal copper width and space for internal and external layers. (For example my manufacturer require minimal copper width/copper space 0.1/0.1mm for external layers and 0.15/0.15mm for internal layers ) To prepare the board I has been change source of gEDA PCB, add the possibility to direct different minimal copper width and space for internal and external layers and use it for DRC check. May be this patch will helpfull to someone else? Here the path for current git snapshot: http://geda.lsol.ru/pcb_ext_int_layer.patch Here gziped binary file that has been build for Ubuntu. http://geda.lsol.ru/pcb.gz -- Best regards, Maxim Feoktistov
