Homebrew PCBs

Greetings Gentlemen,
Have been following this thread and others with interest. 

Was intrigued with the temperature that HP was using on their fusers 
(ceramic - higher, H. Lamp - lower) so I contacted their Tech Support 
and asked them. Seems that their latest model uses a fuser set at 291 
degrees F.  No info on what temperature the toner melts at.

I'm using an old LaserJet 4L and an equally old cloths iron to do my 
work and am not having any real problems.  I preset my iron to a mark 
between Cotton and Linen. I use an 1-1/2 inch pad of paper below the 
board, which I preheat with the iron. When everything's warm, on goes 
the board-etc. and the 'ironing' begins. The hardest thing I have to 
remember is to not press down real hard. If the board is to be double-
sided, after a bit I flip the board and continue ironing. I generally 
do about 2-3 minutes total for a 4x6 board. The largest board to date 
has been a single sided 6x18.

Hope the temp info helps,
Mike
