3. Can Tyco Electronics
supply a complete
Connector Solution?
Yes. These solutions can
take the form of simple
holders with STAX connec-
tors held in place by:
Localized interference
In-molding
Grafting
The holder or frame can be
plastic, silicone rubber, or
metal and typically has low
tooling investment:
Below are examples of
complete connection solutions
in challenging applications.
STAX elastomers are com-
posed of alternating layers of
conductive and non-conduc-
tive silicone rubber. Silicone
rubber is the base material
because it has excellent aging
properties, chemical stability,
electrical reliability, and super-
ior performance in shock and
vibration. It also provides a
gasket-like seal to protect the
contact surfaces.
The conductive layers consist
of tiny metallic particles
dispersed in silicone rubber.
Within each of the conductive
layers, the metallic particles
create thousands of conduc-
tive paths. Therefore, each
conductive layer provides
multiple points of contact at
the substrate interface. While
the conductive layers ensure
contact between mating pads,
the non-conductive layers
isolate the conductive layers
from each other. The alter-
nating STAX construction,
200 conductive layers per inch
(8 per mm), allows multiple
conductive layers to make
contact to a single contact
pad while the non-conductive
layers electrically isolate
adjacent contact pads.
The advantage of this material
construction is that you
achieve 3–4 conductive layers
typically making contact to a
single contact pad on the
board. A single elastomeric
strip (element) is used to con-
nect an entire row of contacts.
The multiple layers coupled
with the thousands of con-
ductive paths in each layer
ensure reliable interconnect.
Why use a
Tyco Electronics
Elastomeric Connector
1 – Simple Implementation
Assembly is easy as making
a sandwich. There is no
soldering, no special tooling
or machinery.
2 – Easily Modified
How often is a standard off-
the-shelf connector ideal for
your application? Smaller
height, higher I/O, greater cur-
rent capacity, lower resistance,
less PCB area are all modifi-
cations that can be made.
3 – Fast
The flexible elastomeric manu-
facturing process allows quick
turn on prototypes (1 week)
to test solutions and rapid
ramp on production. Proto-
types are made with the same
process as production.
4 – No Tooling
An elastomer-only approach
allows the customer to imple-
ment the housing and align-
ment features within existing
plastic or metal structure.
Modifications of elastomer
length, height, and width do
not require tooling.
5 – Reliability
Tyco Electronics elastomeric
products have been tested to
the following:
MIL STD-1344
IEC-68-2
EIA-364
MIL STD-202
JIS C 0020
JEIDA 38
INTEL SPEC 5.1, 5.2

6 – Product Support
Tyco Electronics product
engineers work directly with
customer engineering teams
on modifications and custom
solutions for volume applica-
tions. All aspects of the design
and implementation of the
product are reviewed to ensure
a successful product launch.
Custom Capability
Application requirements vary
dramatically across the many
industries that elastomers are
used. The technology is
flexible in adapting to many
of these requirements but, as
with any product, there are
limits.
1. Determine if an
Elastomeric Connector
is appropriate for the
Application
a) Board-Board separation
> 8.0 mm?
An elastomer cost is tied
closely to material usage
(precious metals). In appli-
cation greater than 8 mm
elastomers lose their price
competitiveness.
b) X-YAlignment (>±0.25 mm)?
Unlike a mechanical male-
female connector an elas-
tomer cannot perform the
alignment of the system.
The reference drawings
show how pins can provide
satisfactory alignment.
Other methods can achieve
the same result.
c) Sliding Contact?
Silicone by the nature of
the product has a high co-
efficient of friction. Sliding a
contacting surface across
the elastomer will not be
reliable.
d) Contact Pitch: <0.8 mm?
Since an elastomeric con-
nector depends on the align-
ment of the mating surfaces
by an external means, con-
tact pitch <0.8 mm is not
easily achievable. However,
board real-estate is minimi-
zed by achieving more
closely-spaced rows of con-
tacts pads than fine-pitch
connectors.
2. Determine if “holder”
functions can be inte-
grated within existing
structure?
The holder is synonymous
with the plastic that sur-
rounds traditional mecha-
nical connectors. The most
efficient and cost effective
way to implement a STAX
connector is by incorpora-
ting a retaining slot into an
existing housing or board
separator as shown on the
reference designs.
