What Are Embedded Silver Contacts In Die?
Product Introduction
Embedded Silver Contacts In Die contact technology completes substrate stamping and silver‑contact embedding within one progressive die station. Silver contacts are locked by surrounding base‑material deformation rather than rivet‑head flaring. This compact structure is well‑suited for space‑constrained miniature electronic components, reducing overall part height while maintaining stable anti‑loosening performance under vibration. Main substrates include beryllium‑copper for relay moving springs and copper alloy for static terminals.
Core Technical Advantages of Silver In-Die Riveting Connections
Low‑Profile Flat Surface
No protruding rivet‑head, suitable for products with strict overall‑height constraints.
01
Material Saving
Optimized silver‑alloy consumption without sacrificing contact working area.
02
Strong Anti‑Vibration Locking
Substrate material wraps the contact periphery, resisting loosening under mechanical shock and vibration.
03
Consistency from One‑Die Forming
Stamping + embedding finished inside a progressive die, reducing secondary‑handling positioning error high batch repeatability.
04
Excellent Electrical Performance
Maintains ultra‑low contact resistance for signal‑level & moderate‑current switching.
