Hey All<div><br></div><div>Been lurking for a bit and thought I would introduce myself. I'm Andre and I'm running the canterbury university aerospace club this year. I've been reading the thread about pcb etching and I've had pretty good success using baking paper for toner transfer. I've been using it for brass etching rather than making pcb's but the concepts and methods are basically the same. I found the the blue peel plastic backing melts too easily, though perhaps that's because the laser printer I'm using might have very high melting point toner? Not sure if that's a reasonable argument. The baking paper can take lots more heat and is very much cheaper. </div>

I had great success with PCB toner transfer. I made some BGA boards this<br>
way. The trick was to use a toasted sandwhich maker hot plate to get it all<br>
hot. I then finished it off with a rubber artwork roller. This is what gave<br>
me the sharp results. Pressing with an iron never worked well for me.<br>
