The the prototyping is done, putting the design proper PCB board makes it more rigid and possible to offer unassembled kit. The process is mostly straight foreword but the design process to lay out the board requires some time to get right.

Setup

  • CAM, Computer Aided Manufacturing, processing files
    • SparkFun CAM
    • Creates the proper gerber files for manufacturing:
      • GTL - Top copper layer
      • GBL - Bottom copper layer
      • GTO - Top silkscreen
      • GBO - Bottom silkscreen
      • GTS - Top soldermask
      • GBS - Bottom soldermask
      • GTP - Top solder paste stensil
      • TXT - Drill coordinates
  • Eagle parts libraries:

PCB Manufacturers

A great place to start is Ladyada's PCB cost calculator.

  • BatchPCB - Easy and cheap for small boards

Board config

  • FR4 - Stands for Flame Retardant and 4 means woven glass reinforced epoxy resin
    • Standard 1.5 mm thickness
