Oh, I just ran down and took those pics after you asked. I am not
sure why the temp setting is cranked all the way up. Perhaps someone
was actually dry-mounting a small pic in a hurry.....
When using PNP Blue, I set it between 350 and 375. When the set temp
is reached, the green light blinks.
The cardboard is another one I cannot easily explain. Obviously
someone else was using it. It could be that someone had used it for
laminating a small business card or something....(hey that may
explain the high temp setting... oh, well)
I primarily posted the pics for information so others could see what
the dry mount press looked like. I got a close-up of the nameplate
to identify it and paid no attention to the setting..
Anyway, this works way better than the Iron method as the lid locks
down and aplies even pressure and temperature to the PNP blue and PCB
material.
When I do 2 sided boards, I drill registration holes in the corners
of the board and the PNP Blue material. I have made some pins that
are ever so slightly thicker than the PCB material I use. I simply
drill the board and PNP material, and insert the pins. The pins make
sure the PNP material stays in register (doesn't slide around). The
pins are not so thick as to keep the heat and pressure from applying
the PNP Blue properly to the PCB. I do one side first, then flip the
board over and press the other side. Then I etch.
I just wish there was an economical way to activate the through holes
and plate the boards. From what I know, that is almost impossible
for the homebrew croud.
