Best place for copper clad boards?
I need some single sided copper clad boards for PCBs on my CNC. Â After looking around, here is what I found:
4×6 & 5×6 Boards:
- Amazon.com – ~$3 for 4×6 board –  (0.125/sq inch)
- Ebay.com - $1.57–$4.25 for 4×6 board –  (0.065/sq inch - 0.153/sq inch)
- Circuitspecialists.com – $3.25 for 4×6 board –  (0.135/sq inch)
- Digikey.com – $5.44 for 4×6 board –  (0.227/sq inch)
- Electronix Express – $1.97 for 5×6 board –  (0.066/sq inch)
- Electronics Goldmine – $1.49 for 4×6 board – (0.062/sq inch)
12×12 Boards:
- Amazon.com – ~$14.57 for 12×12 – (0.101/sq inch)
- Ebay.com -Â $14.65Â for 12×12 – (0.102/sq inch)
Other
- Ebay.com – $7.97 for 200mmx300mm – (0.0133/sq cm) [7.874×11.811 – ~$0.0857/sq inch)
It looks like the Ebay offer for multiple 4×6 boards is the winner, just bought a group of 7 for $11 including shipping so about $0.065/sq inch.

I looked into this a little while ago. In the UK Rapid sell 4×6 SS for GBP0.52. Dipmicro sell some cheap double sided. But Tayda win with 6×6 for $1.12.
