What “MIL-spec” means on an RFQ we can run
We process to the specification on your drawing — not a generic military brochure. Typical defence/aerospace packages call out gold thickness and undercoat, electroless or electrolytic nickel, passivation (ASTM A967 / related), and conversion coating (MIL C 5541 / MIL-DTL-5541). Share the spec revision with the first RFQ.
What plating is used for aerospace connectors?
Aerospace hybrid connectors most often specify gold over nickel on contacts (wear and contact resistance), sometimes silver on high-current terminals, tin only where soldering dominates, and conversion coating or passivation on shells and hardware. SM Finishes runs those finishes under AS9100:2015 change control — the same system used for commercial connector volume.
