Homebrew PCBs

While I had no problems achiving fine traces (15mils) with small 
boards 1 sq in using ironing, it was impossible for me to make a 
100x160mm PCBs and the best I had was 70 or 90% exactness. I went 
thru every possible trick mentioned on this forum to balance the 
temperature, pressure and time and notning gave me results as good as 
using a different heat transfer method (at that time the fuser method 
was not well known). Mike

PS by different heat transfer method I mean using a laminator and 
Staples paper (suggested first by Tom Gootee), And yes I did try all 
kinds of other injet papers, I still have a pile of them and none of 
them worked well on LARGE PCCBs. If TT works well on a large PCB 
therefore it will work well on any smaller PCB as well.
