I get it done from a manufacturer in chickpet "Vishal International"
they are expensive, so I combine multuple types of PCB for prototyping.
 
Re: LM3886 PCB

I get them made from Manufacturer, I only Clone / Re-design them.
Does he have a website? Will he take an order remotely, if I email him the Eagle CAD files or the Gerber files, say?

Remotely does not work with him, he delays a lot, need to follow regularly, he takes some amount in advance, its better to find some manufacturer at your location.

I guess my safest bet then will be PCBPower. They take orders over the Web, and operate in India. Never used them, though.

i have had a very good experience with PCBpower. Very neat production.
i guess they are a little expensive and would be VFM if there is a large quantity.

hope this helps :)
 
I have quote from them, yes they are expensive..

Quite natural! that is the economics of mass production. But I dont think you need external help for a PCB of this size and complexity. simple laser print-hot transfer-FeCl2-varnish coating method is enough for this. for double sided just drill one side before transfering the other side.
 
Hi Sudhir,

It's a small world !

I bought a kit from your ebay store - didnt know you are on HFV !!

I must admit - super prompt responses and detailed replies for my newbie questions.

All the best !

Cheers
