Hi, My name is Jose Kovacevich. This is my first post.
I have been making PCBs for some time now. Lately I have been using
a heat press, of the kind used for t-shirts, and the Staples paper.
I set the press to 200 deg (centigrade), and in 60 seconds, I get a
perfect transfer almost every time (a couple times there were small
track sections in the edges not getting transfered, easily fixed
with permanent marker).
By the way, I am from Monterrey, Mexico.
