Xylene as Developer for Kepro Boards

DSchmidt · 16th January 2006, 10:59 PM

Hi All,

I am experimenting with using Xylene as a developer for kepro photo sensitized resist copper clad boards. I have a good number of these boards which require the KD type developer (these are negative photo resist boards) and the KD developer is pretty pricey. That developer is Xylene based and I got some Xylene from Home Depot (Xylene is used as a thinner for some paints and adhesives), and I have made some progress. I'm wondering if someone has already gone this route, if so, I would appreciate any advise you have to offer. If not, I'll post my "findings" as I get them through trial and error.

Hope all is good with everyone,

David

Ventilation. Solvent-grade mask. Nothing nearby that can have any sparks or flame. Xylene is pretty nasty.
