Special applications such as?

I have the task of coming up with the lead free finishes that we are going
to use. OSP will NOT be one of them (I have been told not to use it).

Changing to lead free has removed a few PCB suppliers from our lists.

Thank you,
Matthew Lamkin.

Immersion Tin is in use as a surface finish for specific applicatios, it is
not classified as an OSP (organic solderability preservative). Some common
OSPs are Benzotriazoles, Immidazoles and Benzimidazoles. they are non
metallic, organic compounds. Hope this is helpful.
