Well, I think I may have done it. First, I made my boards smaller so that they wouldn't sink as much heat. Instead of a 4" x 6" board with 6 circuits on it, it is now 1/3 that size. I ran it through 16 times. No traces came off. Chuck WB2EDV

Did you make any other changes besides the size of the board and the number of passes? TANSTAAFL!

So you had a temperature problem after all. Convert a fuser to run at ~180C and slow and you'll only need one pass. ST

Actually, yes. I used some 600 grit wet/dry sandpaper to clean the board after I'd already used a brillo soap pad, then rubbed down the board with rubbing alcohol. I also humidified the Pulsar paper prior to running it through the laser printer. The smaller board was noticeably hotter to handle. Chuck WB2EDV ----- Original Message -----

It certainly appears that this may be at least a contributing problem, possibly the primary one. Chuck WB2EDV ----- Original Message -----
