Outsourcing PCB fabrication is to have PCBs professionally produced from the files output by your EDA software.
Advantages
This method might seem more expensive, however in the long term it isn't. Professionally produced PCBs can offer much higher quality, with options such as multiple layers, soldermask, plated through vias and silkscreen. These will make assembly easier and save time that might otherwise be spent on debugging potentially low-quality and unreliable PCBs.
Order pooling
Pooling or panel sharing is when the manufacturer combines several different customers’ orders on the same standard manufacturing panel. Boards sharing the same panel need to be all of the same technology, e.g. all two-layer. It is used to cut costs (by as much as 90%) for prototypes and small batch PCBs, in three ways:
- All the pooled orders share the same set of tooling and machine/process set-up.
- Much better use is made of materials.
- Production is much more efficient with standardised panels.
Online pricing and ordering is simplified as the manufacturer will know the set-up and production costs of standard panels for each technology and the price then depends upon the area of panel used by the circuit.[1]
Manufacturers
A list of PCB manufacturers who are more economical for low volume production. Note that a company with the lowest price for one size board won’t have the lowest price for other sizes.
- DF Robot Very good Quality, up to 4 Layers, very cheap.[2]
- Dirt Cheap Dirty Boards, intended for dirt cheap prototype boards
- ITead Studio Very cheap two layer prototype service.[2][3]
- OSH Park Based in USA, ship worldwide.[4]
- Fast Circuits Sacramento based
- PCBYA Very cheap pcb house for prototypes.[2]
- Screenbond Based in the UK. 1 and 2 layer, low tooling cost and cheap for standard turnrounds.[2]
- Seeed Studio Cheap two layer prototype service with thickness and surface finish options, prototype pcb assembly service provided. [2]
- Bittele Electronics Canada based, turnkey pcb assembly
- Asian Circuits
- PCB-CART
- WELLPCB
