Guide how to solder
PCB fabrication
- From 2013 I use PCBnet, excelent quality of boards with soldering mask, and about $15 per 3"x4" board in quantaties of 10
- "Direct Etch" requires special paper, etch setup but can be done at home
- "PCB express" inexpensive fabrication. They accept Eagle files for BPD. See also EagleToPCBexpressConversion
