Gold plating is an extremely demanding process on dry film photoresists; especially in high dep applications. There are ways to optimize the process. Give me some details, and perhaps I can help. How much Ni/Au are you depositing? What is the thickness of the dry film? What are the basic parameters of your gold tank (oz/gal, temp, pH, agitation)? The type of dry film used can have a big impact on the success/failure of gold plating process. We sell a couple of products that have excellent resistance to gold plating. Contact me offline if you would like more information.
