Shipley-Ronal also makes an OSP. Their web site says only:
"Ronacoat OSP A thin Imidazole-based organic solderability preservative
Good for multiple thermal excursions and prolonged shelf life."

<< Hello everyone,
Could you help me out with the following request?
I would like to know what kind of protective coating PCB manufacturers are
using to cover the bare copper at the final stage of the manufacturing.
I know about Entek. Are there others?
What is the thickness applied?
Would bare board test will be carried out before or after that coating?
Where can I find information about the composition of the materials
