Wetting ability

Hi All,

I'm Alex from the Philippines, we are now encounterring problems on wetting ability of some parts. Penetrant (ZL27A, Sensitivity Level3) do not wet some parts surfaces/portion, same thing with the water soluble developer. Is there someobe encounterrred the same problem? What is the rootcause? And what is the best cleaning (not etching) we can use to resolve this?

Thank you.
Alex

Hi Alex
The most common cause for lack of wettability is surface contamination of some discription. What pre cleaning do you currently use, products and process?
