Homebrew PCBs

Hi Mark,

I'm perfectly happy to keep this on the list so everyone may benefit.

One of my questions is about the mechanics. If one sends a rigid PCB
through a laser printer i would expect the edges to eventually damage
the sensitive coating on the drum. Even with careful de-burring
potential for damage seems high.

Another thing is toner density. When i tried printing on metal foil i
noticed i can only achieve 50% of normal toner density, because the HV
that normally holds the toner is shorted out. I did not consider it
possible to achieve enough toner density to resist the etchant.

Generally i much prefer laser printers, i hate the messy ink business.
But with an inkjet the head moves some distance from the surface, so
that is no problem.

Did you use some type of carrier sheet or was the PCB large enough to
be transported by the printer?

Thanks

ST
