Subject: Sealing Toner with a Hot Air Gun - Sponge Rubbing
From: "niponcio" <niponcio@...>

Hi, I remember reading in a post, a while ago, that after transfering
the toner to the PCB, u could seal it with a heat gun, eliminating the
porous surface, getting the same results as with the green TRF Foil.
Ive been searching for that post but I cant find it.
My questions are:
1.- Does this sealing method will work with the sponge rubbing etching
technique.
2.- If so, at what temperature should I set the gun, and for how long
(how do I know the toner is sealed).
Thnx for your help
