The printed circuit boards I had made arrived today. They are good quality and four turned up when I only paid for one! Not bad considering I only placed the order on the 4th Sept. and they have been made in and shipped from China!
This sometimes happens when they have a big space on the PCB blanks that they use. It is cheaper for them to fill as much space as possible and so if they have a small design (like mine) that can fill the gaps with they will use it repeatedly.
Good news for me as the boards work out at £11.50 each. Can't argue with that.
Trouble is though, I seem to have got the silk screen over the pads on one of the surface mount footprints. Ah well.
