To deliver an exact engineering quote and initiate preliminary DFM validation, we require: (1) Vector artwork for graphic overlays (Adobe Illustrator .AI, CorelDRAW, or vector .PDF) specifying Pantone / RAL color codes, window cutouts, and embossing details; (2) Mechanical dimensional drawings (DXF, DWG, or STP) indicating switch dimensions, adhesive boundaries, and connector tail length/exit pinout; and (3) Circuit schematic or CAD Gerber files (RS-274X) outlining silver trace paths, LED polarity, and tail termination pitch (e.g., 1.0mm, 2.54mm FCI/Nicomatic housing). If you only have a functional concept or physical legacy sample, our engineering department provides reverse engineering and PCB cloning services to regenerate complete fabrication packages.
