Hello,
Thanks for the info. on your approach to using the Blue Press and Peel
transfer. Do almost the same except don't have a way of monitoring the
iron's temp. Will look into getting a digital cooking thermometer to check
the iron's temp. "Solving" the temp. issue with transferring the toner
from the Press and Peel to the board will help. Still leaves the sometime
problem of too much iron pressure spreading the toner outside of the wanted
lines. Possibly the thermometer can be used to determine the temp. of the
Harbor Freight laminator. Finding out the roller temp. of the HF
laminator will help determine what modification(s) needs for use with the
Press and Peel material.
By the way, what I do is to make several copies of the PCB artwork with an
inexpensive ink jet printer, cut them out and glue them to a single sheet
of paper. Then have the single sheet copied to the Press and Peel using a
copier at a big box office supply store. This is my way of getting maximum
use from a sheet of Press and Peel. Also, the cost of $0.10 per page is a
lot less than buying a used laser copier and cartridges.
Again, thanks for the tip of using a digital cooking thermometer for
setting the iron's temp.
