Hello Rob,
from the
yea, i tried three times and the first was the best go ???
i am trying a double sided board which is the real trouble as the
2nd heating messes up the other side's etch mask. i tried putting
paper towel, then tissue paper but it still causes problems i
think i maybe moving the board slightly and that is trashing the
resist lines.
thanks for info and ideas,
robb
You iron both sides at the same time.
In your art work, have 2 alignment holes just out side the
trace region that you can later cut off or use 2 mounting
holes that you may have in your art work.
pop out these 2 holes in the final art work on the printed
laser paper. use one side as a marker to get the holes pre drilled
in the board. knock out the holes in the other side of the art work.
using 2 small screws and nuts, put them on each side at the same
time. Find your self a block that will fit between these 2 hole's, so
that you can iron. or.. line up one side first, iron it on. which will
make it stick. then flip it over, place the other sheet on, and iron
that. Using the holes as alignment or course.
etc.
I do this for quick and dirty jobs, it works very well.
The only hassle is if you're doing double sided cross through.
you need to solder on each side with a jumper pin. The solder does not
flow well to the other side because of no plating in the hole.
I found my hot air pencil actually works well in pushing solder
in these holes to connect to the layers.
