Homebrew PCBs

HP LaserJet 1020 and Kodak Soft Gloss - CAT 182 0406

It works great. just peal off the paper while its still hot and its 
ready to etch once it cools.

The traces are 10mil. I measured them at work. The paper is also 10 
mil so it didnt spread out like I thought it did. I looked at it 
under a 10X scope and only had one spot where the trace had a dimple, 
still connected but only half the width.

all that is needed is a quick wipe with alcohol before applying the 
pattern. I only lay a towel on the counter to keep from scorching it, 
but nothing between the paper pattern and iron. Iron set on cotton. I 
use only the weight of the iron, no extra pressure. I do run the tip 
around the edges of the board since the edges seem to loose heat more 
rapidly. I don't use tape to hold the pattern, just put a finger on 
the pattern and put the iron on the other end to get the pattern 
tacked down. Don't have to remove the melted glue that way. I use 220 
grit paper to take off the toner. Acetone works well too.

give the top and bottom of the board a very light spray of clear 
acrylic before assembly. You can solder right thru the acrylic and it 
forms its own solder mask. Helps prevent solder bridges as well.
