Very nice "How to".
Just a point, on the ground plane side, if there is no track or connection, why bother adding a pad, then alignment will be even less crytical.

This was more of an experiment with doing a double sided board using cold toner transfer.  The board was just one that I had ready to etch, and I wanted to check what kind of registration I could get with the cold toner method.  When I build the board I will probably use a drill bit and remove the unneeded pads by hand .
DWayne

What about using the laminator on cold to bond the toner to the board instead of burnishing ?

NICE!



 

Have
tried the single
side cold method myself with very good results. Looking at
your double sided
results, I guess the laminator has had it…

Have not tried.  But it is much easier to grab a fork , than to get out and set up the laminator.
Only burnishing with moderate pressure for a bout a minute or so.

Hi Roland

A good idea with the cold laminator, I never thought of it. Thank you.

By the way the roller you are using is a roller to apply ink on linoleum carvings. Probably available in a craft store at your end.

Malcom Parker:

Good Idea:

I use a rubber roller.......looks something like a paint roller, only smaller and with a rubber roller instead of

fuzzy felt.

If I had a laminator, I would use it with no heat, just to apply even pressure across the surface.

One pass should be sufficient.

Regards,

Roland F. Harriston, P.D.
