Thanks csaba911...thanks for the help..
so this will work..have tried it..is it good or bad..i mean does it protects te track by coroding..
I can't tell, haven't tried yet.
Looking for my old college friend who is get his fist job in a photo printing lab.
He was showing some liquid witch dissolve in solvent after exposed to UV, the rest need to be baked on 130C for 30 min and rock solid.
It was applied with silkscreen process on metal plate !
The one he was using is very dark blue and shiny !
No response from him, he may changed his mail or don't remember me ?~! "11 year"
Hoping to get a few 100mL or more.
Anyone know about this liquid?
Hate to spend $25 US+ S/H for a small bottle.

hey, i'm not sure with this but i think the presencitize pcb is the one you can use......
I think you are talking about the **broken link removed**.
This is good stuff, solder mask is the next stage after etching the PCB, and this last layer of ?ink?layer should be very resistant to solvent's and other dissolving solution.
Googled for "solvent developable soldermask" but nothing specific.
Suggestions welcome !!
