For the record, whilst I get most of my PCBs done at www.oshpark.com, for larger boards that would otherwise be too costly, or for simple boards I just need in a hurry, I use positive photoresist. I use ammonium persulphate as an etchant; what ferric chloride doesn't attack, it stains; filthy, messy, stuff. Ammonium (or sodium) persulphate *much* nicer to work with (I use a bubble etch tank.) -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
