: : : : I want procedure for making 2 side PCB's Anybody knows it? A link to E-book is welcomed.

: : : I believe radioshack has kits for that, but it seems to be the one thing they're useful for. Otherwise, search online for a pcb supplier and order some to your specs. There are many free *nix programs to design them, and most of the places give you software to use.

: : I know & use OrCAD very well. I can do the artwork very well
: : What I want is the practical procedure of PCB manufacturing i.e. plated
: : through hole tech, tinning, masking, etc. 1 can find many professionals
: : doing this, but no one will tell. I want to become a PCB manufacturer. A person who leaved this field can tell. Can u?
: : Amit
: Do some research, I just grabbed this real quick off of excite:
: Anyway, I'd recommend taking a couple chemestry classes, you'll need it. As far as I know, there are 2 different methods. The first involves creating a mask of some material that blocks a specific wavelength of light, then shining a light of that wavelength onto the copper plate on the pcb, in such a way that the light vaporizes the material.
: The second involves printing, on the circuit board copper, a material that resists a specific copper eating acid, then dunkingthe pcb in a tank of that acid until everything else is gone.
: I also believe it's possible to do it a third way, where you take the pcb material that you specifically chose because it doesn't burn before copper melts, coat it with something that copper doesn't bond to where you want no copper, and dunking it in molten copper. This seems like a good way to make plated through-holes, but they may become plugged and need to be repaired. Perhaps if the molten copper were placed on it like a printer, and there were a device to stick through the holes and coat the inside of them with a spray, it could work.
: Also, check out
: It may help.
thanks for that I'll be looking at this & ask u for any query
