TT: getting the toner to stick

2004-03-07 by Phil

I've been playing around with different papers and was very surprised 
to find that regular old ink jet paper actually seemed to have
some potential but tended to pop up when I lifted the iron.  There 
was clearly some transfer going on so I modified my technique and 
after about 2 minutes a side, turned off the iron and left it sitting 
on the board/paper assembly.  once it was cool well below the toner 
fusing point, I soaked and rubbed.  To my delight, I got an excellent 
transfer.  There was almost none of the blotchiness that I had been 
getting earlier.  I attribute this to the paper being porous and 
soaking up any extra toner.  There was very good adhesion, even a 
good scrubbing with scotchbright didn't budge the resist.  I'm really 
glad because I was annoying my wife by cutting out magazine pages.

This was a double sided, 10 mil trace board. 3" x 2.5" so not super 
large.

also, I decided to print the legend (tplace layer for eagle users) 
and try to transfer that.  It worked pretty well, I just ironed it on 
and peeled it off hot.  It wasn't thick enough for a resist but 
legible.  I used a 220 wet-n-dry sandpaper on the board to roughen it 
up.

The paper is Office Depot Inkjet Paper. 24 lb, 92 brightness.  item
