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
A number of people have used a number of different companies for PCB fabrication. For some kind of reference, 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).
| Service | Approx Turnaround time | Approx Shipping time | Silkscreen | Cheapest shipping cost | Total quote | Number of PCBs | Cost per PCB (delivered) |

| OSHPark see specs | 12 days | 7 - 14 days | Purple only | £0.00 (included) | £4.50 | 3 | £1.50 |
| PCB Train Express service (no silkscreen, just copper) | 2 days | ? | None | £0.00 (included) | £30.00 | 1 | £30.00 |
| PCB Train 2 layer (with soldermask and silkscreen) | 10 days | ? | Green only | £0.00 (included) | £44.10 | 1 | £44.10 |

| PCB Pool 2 layer (silkscreen + soldermask) | 8 days | ? | Green | ? | £117.30 | 10 | £11.73 |
| ITead 2 layer | ? | 4 - 5 days | Green | £2.29 (Airmail) | £8.10 | 1 | £8.10 |
