P2P is a lazy way to assemble???????????





Seriously though, P2P when done well can't be beaten. Whether in 1980 or today. P2P done badly will be bad.

It's not the tool but the workman that counts.

It is easy to get in touch with someone getting made pcb for his own production. Then he gets samples free of charge from the supplier. they do samples with photo etching process. This is simple & fast method.
Otherwise make a group of people who want same kind of PCB, then it is easy to go ahead. We can order with some component supplier who will manage evrything including components.
This is the simplest & most cost effective way.

Sivan,

I got some boards made in Bangalore. Like the others said, the quality is not as good as what you see on the net. It is still quite cheap, about 60/- a board.

What exactly are you after ?

anyone going for ordering PCBs from above source....
well i'll suggest that if ur requirement is for 2-5 Pcbs, U can make easily at home... i am ready to help at any stage and share where i had problems. And it takes 30 mins for etching, 1 hr for drilling (with a small homemade pcb drill), and really believe me, its not a big deal to make PCB.

i had made around 15 lm4780 (& 10 lm3886) pcbs at home, and all are working. still i am having 5 undrilled pcbs left which i can supply you.

Check out my post on lm4780 PCBs
