Homebrew PCBs

I started out using magazine paper.  It has the nice property that it 
doesn't leave a lot of residue.  However, because of the coatings, 
excess toner has no where to go and squeezes out between the paper 
and copper.  I was winding up with blotchy traces.  I've heard this 
called "toner crush".  I spent a lot of time playing with different 
pressures and amount of toner (darkness setting on my copier) to only 
moderate effect.  

Then I tried a good quality of inkjet paper and will never use 
magazine paper again.  It works great, is cheap and, best of all, 
excess toner gets absorbed  by the paper.  My traces are quite 
straight and edges are crisp.  It seems to need a higher heat setting 
than magazine paper but you can apply a LOT of pressure and get good 
adhesion of toner to copper.  One thing I do that seems to make the 
toner stick better is turn the iron off and leave it on the 
board/paper assembly until cooled down below the fusing temperature.

There are several inkjet papers that will work in the database.
