Centre d'aide PCB Engineering Questions

PCB Engineering Questions: Gerber files are not completed; The parameters in gerber files are different from the order details online.; V-cut standard-Limited to Quick-turn PCB; Slots standard size - Limited to Quick-turn PCB; Soldermask bridge; Confirm the panel way of the boards; Vias process of design is different from order details option; Some drills overlap the slots at GM or GKO; The outline of shape is too thick to ensure the dimension of PCB; The layout of PCB is unclear; Solder mask layer is opening entirely; Some Issues concerning BGA(Ball Grid Array); Design has no silkscreen layer but online is yes with silkscreen; Please clarify 1-layer or 2-layer; Requirement about castellated holes; The distance between the trace and board outline is less than 0.25mm; The holes is in the trace and it will cause open circuit; The are some pads out of the board outline; Two silkscreen files in your gerber file; Route Process in panel file; Break lines exist in your file; Several gerber files have in your order; Solder mask file is empty or None; Stackup information; The tab route is smaller than 1.6mm; V-scoring line/Slot in silkscreen layer; Line/Shapes in GM layer; UL Marking; Legends on Copper layer; No Gold fingers design in file; Drills hurt the circuit; No Drills in your file; Legend on every layer; Soldermask opening for Gold fingers; Remark for drills is not fitted with the actual drill table in file; BGA pad opening; Board outline design standard; The holes design standard; There is only top solder mask layer in your file; Without D-code; Spiral coil board; the spacing requirement from slot to copper trace; Edge plating; the spacing requirement from hole to the edge of board; The spacing from one hole to another is too narrow; It is wrong that copper traces are solder mask opening; pls confirm whether solid rectangle area should be made as slot or not; The requirement of beveling on gold finger area; all the holes are with the same size; The castellated holes are partial set in outline instead of in the center for common designs; stamp holes standard; min non-plated holes; the hole limitation for single-side Aluminum boards; the spacing from hole to trace; silkscreen over pads; limited holes spacing; the bottom silkscreen is mirrored; Do you need round holes or slots holes made?; Mask openings are smaller than copper pads; notes in the order are different from the designs in the files; do not design texts on the copper layer; drills are not matched with pads; Negative or positive inner layer; NPTH design rule; Silkscreen standard size; Spacing between silkscreen and openings; silkscreen size and spacing in solder mask layer; How to design cutout or big hole; Remark on rectangle slot; How to regard GPT or GTP; Negative legends in copper layer; Slot in oval pads; Which layer to put round or any shape of cutout; There do not have fiducial marks or tooling holes on break away rails; There is no stamp holes on tab routing; The non plated holes break traces; No layer orders for multi layers boards; There is no solder mask openings on some pads; The layer order information you filled online doesn’t match the name suffix in gerber file; Copper line and the pad are not connected; There are no drills in the areas pointed with arrows; Solder mask opening of some pads is too much which cause copper open as well; PCB file you uploaded seems the production file, not the original PCB file; Negative legend dimension is too small for production
