Robin, It does make sense that this transfer paper is coated with plastic and not wax. Your tests are reasonable. So if this really is polyethylene bonded to

... You just iron it or run through a laminator like with standard toner transfer. It s just a coated paper so that the toner sticks to the coating

Hi Rick Yes I have noticed your determination and you have done well. I don t to come across as dumb but exactly what powder surface are you referring to? is

Thanks charles After reading your findings I may well not bother with it, just keep to the copper surface. Normally when building equipment like metal

Dave, I don t think I have played in an area nearly as complex as toner transfer. There are so many variables and so many options. Numerous times I have come

If tining before etching works well, I wonder why you don t see pre-tinned copper clad boards? I suppose it limits you choice of etchant.

Hello, It is not just as simple. If possible, all the pcb fabs will do that. Regards.

Not very practical. The electroless copper first laid down is very thin -- just enough copper to get electrical conductivity. Furthermore you have to have

Fernando, There is no single answer here. Sure, CNC could be used to make boards. Most people send their artwork to China and get boards back in the mail.
