Dear Friends,
I am trying to setup a small prototyping facility for testing my designs.
Usually my designs are single sided,until now I used to make it using
OHP marker pens and FeCl as etchants as these things are easily
available in India.

Since this technic requires an artistic hand and has zero
repeatability ( for at least 2-3 boards) I want to use photo etch method.

I tried transferring the artwork by screen printing (silk screen),it
is a popular method for visiting cards here, on copper clad, but
there were lot of pinholes.

I tries tone transfer but my printers are all 600dpi laser again I get
pinholes.

Now since I can get the films done easily I want to understand how to
do photo etch without a pre-sesitized board which is not available here.

Can anyone help me with the name of the photoresist that I can find
here in India?


Any help is appreciated.
Awaiting for your replies

Thanking you
Deepak
