Homebrew PCBs

Another fellow was going to try using a heat gun after the toner 
transfer process.  Seeing as I messed up so good on my last two 
boards and had to remake them, I figured I would give it a try. 

I transferred the two circuits onto the boards - perfect transfers, 
no pick ups or anything like that.  This time I used the iron again, 
set at 370 degrees F, and pressed 3 times at 10 seconds each time. 
Each time I pressed, I made sure to move and rotate the iron a bit 
so the steam hole areas were not on the same spot on the circuit 
board.  Really came out nice this time - very impressive.

I then took the heat gun and flashed over the circuit boards till it 
appeared that the toner turned a bit glossy.  My eyes are acting up 
a bit today, so tomorrow I will look over the toner with a glass to 
see if it looks like the toner "blended" together under the heat.


If time allows, I will etch and tin the boards tomorrow.  Again, 
will post results.

So far, that pulsar paper is working good for me, but frankly it is 
expensive.  However, if it works reliably, I don't mind the cost as 
I don't do enough boards to justify another method using a cheaper 
paper - yet.
