Nice Ajay jee !!idea_factory said:Hi,
We are from China manufacturing of spray etching machines, We have developed a solution of liquid photo resist in a laboratory here for our etching customers, as photo resist from USA and other countries are very expensive
This resist has a capability to expose even a hairline, as we sell double side exposure machines also for double side PCB we can expose both sides with this Photo Resist.
We are selling this in India, for pricing and details mail us at sales(at)ideafactory.co.in

Dear Rajudp,
The result is amazing. i am using wet lamination method.
I have a self made exposure box with Philips actinic BL 20 x2 tubes with a hight of 6 inch.
The first trial with 12 min exposure tracks are very good but the SMD pads are all joints.
The second trial with 5 min exposure 95% of tracks are perfect. 5% tarcks are joints in SMD.
Now tring the third trial with 2 min exposure.
