     Dynachem makes a good film for gold plating.  Of course the better
     films for adhesion are also harder to develop completely & to strip
     off later.  Their 500 series film is good for gold.

I work in gold plating. We are using electrolytic gold plating.

It is pattern plating. However the gold leaks underneath the dry film.

As a result the pattern is fatter after the dry film is removed.

We develop the pattern dry film and thenn hardenn the dry film by

exposing under UV light again. But still it leaks underneath the dry

film. Could any one help ?

WE also want to set up a pulse plating bath ourselves. Could any

one give us some information onn how to start ?

Thanks in advance!!!!!!!!
