Stripping of TiN
Anyone knows the chemical mechanism of stripping off TiN in NH4OH/H2O2/H2O? Does the amount of water affect the reaction? Many thanks.

Tin stripping is generally done with solution containing nitric acid and is usually faster. For stripping on MS Fluoboric acid is also used. But the same cannot be used for stripping of tin on PCBs. To prevent the attack on base metal sulphamic acid is used. The amount of sulphamic acid to be used is critical. I am looking for the same and will let you know as soon as I get it.
