I'm looking to purchase some pre-sensitized copper clad boards so I can make some PCBs. People familar with Do-It-Yourself PCBs ought to be familiar with this method. This is what I'm looking for: http://uk.farnell.com/kelan/141301/pcb-photo-resist-d-s-100x160mm/dp/141301
You transfer your PCB artwork via UV light and transparencies. Once that is done, you develop the board and etch it. Anyone know if I can find such boards in Pakistan? I've found double-sided boards but with double sided boards, it can be tricky to fill the vias at home. I suppose I could just develop one side and forget the other but that feels like a waste.
But I have found Dry Photoresist Films that can be applied onto the normal copper boards found. However, that requires Hot Roll Lamination and I'm not sure if I can find that here. In anycase, its just a further variable in the process that I'm hoping to avoid.
My second question is that I know there are several PCB manufacturers in Pakistan. But are there any manufacturers that will do a "one-off" PCB for the purpose of prototyping? I ask because I'm designing a circuit for a company that requires surface mount components and is complex enough that routing needs to be done on a double-sided board. But before I finalize the design, I need to test it and work through the problems and the only I can do that is if I have a PCB made from the PCB manufacturer. Anyone have any suggestions regarding this?
