I was asked by one client for the test procedure of parylene coated PCB from SULFUR attack.
Is it any professional method or standard to perform this precisely and quantified ?
Thank You !
First, I'd ask some clarifying questions about the environment, namely what kind of sulfur compounds they expect to contact their PCB.
Second, ASTM G85 Annex 4 contains a SO2 modification to ASTM B117, which may be used to provide comparative results between coating systems.
Thank you very much Andrew.
