Homebrew PCBs

I finally got a good toner transfer on the 1/32" board. Now I need to 
fill the pin holes.

I do have some Sharpies here. But I also ave some artists acrylic pens. 

Has anyone ever tried the acrylic pens?

First I tried this on 1/16" stock. When that worked I
went to the 1/32" piece.

What I had been doing is just holding the iron in one
place under a much pressure as I could generate for 5
minutes. My board is small enough to fit the area of
the iron that has no holed. But I got very
inconsistant results that way.

I held the TT paper in place with one finger while I
tacked it to the copper. Once it was tacked to the
copper I "IRONED" it with the tip of the iron for 5
minutes.Buy the time I had dome this for 5 minutes the
top of the paper was almost totally black. Then I put
it in the water for the 10 minute soaking period.

At least this is a starter.

Now I need to clean it up before etching. This is a
double sided board. I don't expect this one to be
useable. Right now this is a learning process.

I am a retired EE. I was close to the PCB industry for
many years. I laid out PCBs for a living at times. I
am using Orcad for the artwork.

I don't get pinholes!!

Look at my post under TT Technique.

Use the right paper.
