SMT-ETI-1 STAX™ Connector
Tyco Electronics Elastomeric Technologies™ continues to demonstrate technology leader-ship
with the introduction of the INDUSTRY’S FIRST surface-mount elastomeric connector product.
The SMT-ETI-1 is a dedicated single position connector used in lieu of a spring-finger, pogo-pin,
or compliant materials in portable electronic and communication devices. The applications include
grounding, power connection, and shielding to eliminate EMI and RFI.
The SMT-ETI-1 is an integration of Tyco Electronics’ ETI and
MID technologies:

A STAX™ elastomer has the widest range of deflection in low
profile connection (5 thru 65 %) while maintaining consistent
performance and reliability. Combining the standard base with
the flexibility of the elastomeric manufacturing process allows
for an optimized connector for each application.
This minimizes the deflection forces while compensating for
z-axis tolerances. The silicone provides the normal force of the
connector, seals the contact interface, and even conforms to
irregular surfaces. Standard parts are available – modifications
can be easily created.
The electrical characteristics of the SMT-ETI-1 rival all competitive
technologies in resistance and current carrying capacity.
The SMT-ETI-1 STAX connector features silver particles
embedded within a low durometer silicone. Within each of the
conductive layers, the conductive particles create thousands
of conductive paths. Each conductive layer provides multiple
points of contact to the substrate interface.
The pitch of the conductive layers is only 0.127 mm (0.005″),
allowing multiple conductive layers to make contact to each
substrate pad.
All specifications subject to change. Consult Tyco Electronics for latest specifications.
The surface mount holder is a gold plated plastic and
provides a low profile – small form factor “standard” base.
A STAX™ HT (high temperature resistant) elastomer is
grafted into the SMT holder for a single-piece assembly.
