I'm in the UK and I want to buy some single sided copper boards for home manufacture of PCBs. The size I want is 250mm x 130-140mm. Can anyone recommend a supplier please?
Does it have to be FR4? That is normally only used for high frequencies. Anyway these people have PCB http://www.rapidonline.com/Electronic-Components
as do these http://uk.farnell.com/
If it's not FR4, then its most likely phenolic, which can seem like cardboard.
