HOW TO – Make PCB’s with a laser printer

Ummmm.. did he say keep the iron pressed to the paper for 5 minutes?
Perhaps he meant 5 SECONDS?
I think that the paper would catch fire after more than a few second.
Besides using a laser printer, one should be able to make this type of etching mask using a photocopier as well, since it also prints with thermally set toners.
I’m sure he is correct about ironing the transfer for 5 minutes. Paper handles being ironed just fine. With the iron’s temperature setting on “silk”, the iron will only get to about 150°C (300°F) – well below paper’s flash point of 233°C (451°F). That temperature should be enough to bond the toner to the copper. The paper may get a little brown, however, if the iron is left stationary too long, but it won’t ignite. Frankly I’d be more worried about melting the board’s plastic base.
