Darn, almost perfect transfer...

2005-09-07 by lcdpublishing

Well,

I had a few minutes so I went out to the shop to transfer the 
artwork to the circuit boards.  First one came out REALLY good 
except for two little spots that were easy to repair with a marker.

The second board started out looking great, but by the time the 
paper came off, it was a mess.  

I think I know what I was doing wrong the last few times.  Based on 
a lot of the posting here, I figured the "pressing" time at around 
90 seconds or so.  But with the pulsar paper, that is too long.  Re-
reading their instructions, they say about 10 to 20 seconds which is 
what i did today.  Much better looking transfer, but poor adhesion.  

Then as luck would have it I am out of acetone.  So, my next attempt 
will be to try a slightly higher temp and a few seconds longer.  

Will post results tomorrow if I have time to do it.

Chris
