Homebrew PCBs

Josh,

I feel your pain!  I too am working with this stuff, I am on my second roll now.  Some boards 
turn out perfect, others, not so good.

I have not found a reliable method of applying the film without bubbles.  I am using a 
laminator with two heat settings, same results on both settings.  I have not yet tried running 
the board through the laminator BEFORE it heats up though.  I suspect this may help in 
getting the bubbles out before the bonding occurs.

If I don't get this worked out soon, I am going to abandon the film and just buy pre-coated 
boards.  In the end, it is probably going to be cheaper provided you get better and more 
consistent results.

Sorry I couldn't be of more help.

Chris
