Guides/PCB Fabrication

This is a guide on generally how to get PCBs fabricated. It is NOT a guide on how to etch PCBs - that's the PCB Etching Instructions page.

Introduction

There comes a time when an electronic circuit just needs something a bit more permanent to be built on. That's when you will want to build a PCB.

Etching in the space

The space has some etching facilities, for which you can view the instructions here: PCB Etching Instructions.

Be warned, though, there are no tinning, through hole plating, silk screening facilities. It's great to get you by for a quick turnaround prototype, but for anything more fancy, you'll probably want to send your design off to the professionals.

Fabrication Houses

There are a number of places which can fabricate your board, here are some possibilities

• UK/EU commercial suppliers. Fairly expensive but can be fast and good quality.
  • Spirit Pretty well priced. Also provide a free & fast 'Naked' PCB service [1]
  • Stickleback "offers a good low cost pcb service for 2 layers PTH provided that you don't want less than an 0.6mm hole size and an 0.2mm wide track or feature"[2]
  • Eurocircuits EU based PCB house - several proto services. Fairly cheap for stainless SMT stencils.
  • PWT UK based full-capability PCB place for stuff Screenbond can't do. Typically cheaper than Eurociruits for 4-layer
  • Screenbond UK based PCB house with unusually low tooling costs (typ £40). 1 & 2 layer only. Can do 24hr turnround if you have deep pockets.
  • PCB-Pool Proto/low-volume oriented PCB service, not the cheapest these days but offer a free stainless SMT stencil.
  • PCB Train Fast turn around, good prices. Also have an assembly service and a 1 day (~£40 all in) prototype service for uncoated 2 layer boards.
• Far-eastern commercial suppliers. Probably cheaper for really large batches
  • PCBCART PCBs from China. Very cheap once you get over a square foot or two. Reliable, Quality generally good. A gazillion options - funky resist & silk colours (Matt black is cool!) , thicknesses etc.
  • Elecrow
• Far-eastern hobbyist suppliers such as Seeed Studio.
• Community cooperatives such as DorkbotPDX combine designs from multiple users to make an economic panel, then split it up.

Comparisons

For some kind of reference for comparison, here is a table of quotes for a fairly standard small board:

• Minimum quantity of boards
• 20x50mm
• 2-layer board
• No particularly coloured silkscreen/soldermask
• Through hole plating
• 1oz copper
• HASL or immersion silvering (whichever is cheaper)
• FR4 1.6mm (or nearest cheapest equivalent).
