Homebrew PCBs

Hi Alan, thanks for the reply.  I use a digital thermometer to 
set/check the temp of the iron.  I have had great success at 380 
degrees F so I always use that setting.  However, in the mess for 
the last few days, I have tried anything from 240 degrees F all the 
way up to 440 degrees F with about a 40-50 degree increment --- all 
with the same results.

Darn this is frustrating, especially when the last few boards I did 
were outstanding.  Oh well, tomorrow is another day and perhaps the 
moon and the sun will be in the proper alignment again so I can get 
good toner transfer to copper again.
