Plating Hybrid Connectors for Japanese OEMs
Japanese connector and automotive SQA teams judge a plating house on thickness control, change control and PPAP language — not on brochure photography. This note explains how SM Finishes in Bengaluru works those programmes.
Hybrid connectors for Japanese OEM platforms combine signal, power and sometimes high-speed data in one housing. Gold on the signal contact, tin on the solder tail and nickel on the shell is a common stack. Each layer has to be documented as if it were an aerospace process, even when the part is automotive.
SM Finishes holds ISO 9001:2015, AS9100:2015 and ZED Bronze. We have PPAP audit and release experience including Suzuki Motor Corporation, Japan, plus Maruti Suzuki, Schneider Electric and Kostal. OEM programmes include SpaceX and Israel Defence. Founder William Anthony Raj J has 27 years in surface engineering; the company has operated from Machohalli, Magadi Road, Bengaluru since 2019.
What to send in a Japan RFQ
- Plating specification (including Japanese OEM standards if they apply) and thickness on functional vs non-functional areas.
- Annual volume, packaging, and whether the part ships to Japan or to an India/ASEAN plant of a Japanese OEM.
- PPAP level and whether first-article is required before SOP.
