Homebrew PCBs

Usually it's just replacing the thermal cut-out for a high rated one.

 

This sort of thing:
http://www.apart4u.co.uk/thermal-cut-out-switch-l120c.html, although that
price is a tad high, they're normally a dollar or two.

 

It might take a bit of trial & error to get the right one, and you'll
usually want to get the one above the temperature you're after, so if you
want 150C, go for the 170C one instead.

 

The 150C one will cut out at 150C (as you'd expect), but won't turn on again
until it's about 20-30C below that, so it'll cool down to 120-130C before
heating up again, and that's too cold.

 

The 170C one will run at 140-170C which might work ok.  If not get the next
one..

 

Check the datasheet for the exact range, but it'll be something like that.

 

There also might be a thermal fuse that will need replacing or bypassing.

There was some discussion in the past about modifying laminators for higher
temperature and thicker boards.
I made one from a photocopier fuser unit so can't say what that would
involve exactly.

Also the board I am trying to do is TOO thick

If you use a laminator (or fuser unit from a laser printer) you will
eliminate this problem of variable board size.

I haven't done a board of any size with success using an iron, at least not
consistently.

The higher the wattage the more heat the iron will put out. I am trying to
do toner transfer to a board that is more than twice the size of the surface
of the iron. It is also 2 oz. and double sided. The board itself will suck
heat away from the area I am trying to transfer the toner to. Has anyone
done a board of this type and size with success? What Size iron in wattage
did you use... THANKS for all answers....
