Subject: Re: [Homebrew_PCBs] toner / lacquer thinner

Richard:

I think that there might be a number of compounds that are generally
called "lacquer thinner".
Can you provide the brand name of the item you are using and where it
can be obtained in the USA?

I have always had a notion that the bare copper could be "treated" with
a material that would promote
better adhesion of the toner to the copper, but never investigated.

Sounds like your lacquer treatment might be worth a try.

Thanks,

Roland F. Harriston, P.D.
