Silver Contact Brass Terminal Riveting

Mechanical interlock and cold‑flow deformation secure the silver contact tip directly into the pre‑punched brass base. This eliminates micro‑gaps, prevents loosening under thermal expansion, and ensures optimal current transfer without high‑resistance bottlenecks.

Progressive stamping dies fabricated with carbide inserts yield burr‑free brass terminals. Pitch accuracy is maintained within tight limits to ensure seamless feeding into automated downstream injection molding or relay housing assembly fixtures.

The combination of high‑conductivity brass and silver‑metal oxide contact material restricts Joule heating during sustained current carriage, preventing premature thermal degradation of surrounding polymeric enclosures.

Bare brass surfaces can be selectively or totally protected via chemical passivation, nickel flash plating, or tin electroplating to inhibit oxidation during long‑term warehouse storage and humid operational environments.

Incoming brass coils and silver wire raw materials undergo optical emission spectrometry (OES) verification to confirm exact elemental composition before entering production.

High‑speed automated camera inspection systems scan every manufactured batch to reject components with surface blemishes, eccentric riveting, or out‑of‑tolerance dimensions.

Regular destructive push‑out tests and micro‑section metallographic examinations are performed to measure the exact intermetallic interface strength of the riveted joint.

Sample batches are subjected to salt spray corrosion testing and thermal shock cycling to validate long‑term reliability under severe field conditions.
