Homebrew PCBs

I recently received some very thin pcb material. It was 0.5 oz and 
very flexible, (0.020"?) I could easily curve it around a 1" rod.

I have an old Laserjet IIp+ laser printer, that I have been using 
for toner transfer. The LJ is old, heavy and built like a 
locomotive, so I thoough I would try printing directly on the pcb 
material. I put in an old cartidge and gave it a go.

A 3" x 5" piece of pcb was attached to a regular sheet of paper with 
heat proof labels. I slightly precurved the pcb material. The pcb 
matereial ran through the LJ without a hitch!

Unfortunately, the toner barely stuck to the pcb and was reprinted 
on the paper. I tried again after an extra cleaning step, but to no 
avail.

It appeared that the toner was not fused and was still powdery. The 
fuser in the LJ may not have enough power to handle the 0.5 oz 
copper.

So much for a good idea, back to the foil and the laminator.
