Rhistone from Dupont is one example. There are more suppliers. The PCB
industry is using kilometers of these materials.

Subject: [mems-talk] Dry film photoresist for electroplating

Hi guys,

Does anyone know a good and cheap type of dry film photoresist that has good
adhesion to PCB (Cu surface)? We want to use the PR mold for Zn/Sn plating.
The minimum feature is about 50~60 um width straight lines.

Thank you.

Regards,
