Back in the 70's I printed on mylar film then exposed copper clad board to UV
for about 10 minutes. For more intense boards it was rub on to the film at
10:1 then reduced to file 1:1. The hard part was drilling a few 100 holes.
Have been using JLCPCB for years now. I wanted to use board houses state side
but cost was way to high for small runs.
Only time I used the iron transfer was from a few magazine projects. Worked ok
but still used a marker to darken a few thicker traces.
A run of 25 power supply boards was all hand drawn. Not bad but again drilling
all the holes was a pain.
