Hi all,
I would like to ask all how to transfer the PCB layout artwork on to a copper clad board. I draw it manually but it does not give professional results.
Here in India, I do not think we get fancy stuff to transfer layouts. DIYers in India, please help. Thanks in advance.
Cheers,
Vivek

Hello Vivek,
Have you tried laser printing onto OHP film then using a clothes iron to transfer the toner to the board? This method does work quite well but needs a lot of care with getting the iron temperature right. A search of the fourms will turn up plenty of suggestions.
Nice one,
David.

3rd prargraph. The hints about etching are also helpful.
I presume you can buy copper-clad board coated with positive photo-resist lacquer i never made such from the scratch. If you have t lacquer the copper-clad boards with photo-resist yourself, you have to hassle out yourselfhow to lighten, develop and fixate it.
The 50gr paper (which is opaquely transparent) did a fine job for me so far. Just print your layout scale 1:1 on the paper and make sure the print side is in contact with the photo resist lacquer.
With the local PCB stuff and the UV face tanner described in my post, i need 26min of exposure at tanner distance of 32cm to get the photo-resist lighentend properly. But then results are superior.
Warning: do not use "transparent paper" like used for technical drawings. Use white 50gr paper.

Hi,
Thanks for the suggestions. The problem is that I do not know if lacquer and other stuff is available in small quantities in India. I will try to get hold of it. A laser printer is no problem though.

i used a HP inkjet printer but a laser printer should do fine, provided it processes the thin paper.
PCB:
http://www.bungard.com/p-orig.htm. the best pre-sensitized stuff (copper-clad laminate coated with photo-resist) imaginable and TMK they ship to international destinations.
Other useful Bungard stuff: http://www.bungard.com/consumables.htm
May i suggest a group purchase for diyAudio members from India?
