This is to hold the QFN in a fixed position while we engrave the necessary numbering for our chips. The + sign indicates the 0,0 reference point of the laser engraver of choice. The o sign indicates the orientation of the first pin of the package must face upwards. An SVG file will be included, which was used to generate the PDF needed to use this bracket. There is a tolerance of 1 mm, which may not be ideal but worked for our application needs. The laser engravers we used were Rayjet 50 models. A potential improvement would be to make the grooves smaller for a better fit. Print Settings: Printer Brand: LulzBot Printer Model: TAZ 6 Rafts: No Supports: No Infill: None
