Zebra® Silver

Zebra® Silver High Performance Silver Connectors
Additional options for this product are available here.

FUJIPOLY low resistance ZEBRA® elastomeric connectors are constructed of alternating parallel layers of electrically conductive and non-conductive silicone elastomer. The electrically conductive layer is filled with silver-metal particles. The composite alternating layers provide reliable electrical connection when placed between two aligned conducting surfaces.

The low resistance ZEBRA® provides a redundant connection with a minimum of two conductive layers recommended per PC contact pad. The connector is available with insulating barrier or silicone supports (See page 6). The connectors are used for connecting electroluminescent (EL) and plasma type displays to PC boards or for connecting hybrid circuits to PC boards, among other applications.

Zebra® Silver

Low resistance ZEBRA® connectors are positioned between two aligned surfaces and are mechanically clamped together with a lid or another PC board. The connectors may be free standing or positioned in a retainer depending on packaging profiles and design.

Self-Support and Insulation Barrier
Self-Support and Insulation BarrierInsulation Barrier

Details show silicone support and insulation barrier. Each is available on one or both sides. Configurations may also include support on one side and insulation on the other.

Note: Recommended Height (H) should be twice Width (W) dimension for minimum force deflection. Maximum Skewness 2% of Height.

Design Recomendations

Recommended deflection range is 5-25% of free height. Minimum deflection will vary with packaging applications and should consider overall height, PC board warpage, finish, etc.(Contact FUJIPOLY Product Application Engineering for assistance.) Design recommendations for solid ZEBRA® over 0.400” deflect 0.050” maximum. Silicone supported over 0.400” deflect 0.060” typical.

Test Conditions

The use of an insulating barrier or silicone self-support material on one or both sides of the connector is recommended. The silicone support is utilized to reduce clamp force and provide an element of environmental protection for a cost-effective connection.

Nominal Resistance Calculation

For the purpose of calculating the resistance of silver ZEBRA® connectors and testing them for compliance please use the following formula:
Where:
R = Resistance in Ohms
W1- = Width of ZEBRA® portion (inches or mm)
Ew = Electrode pad width (inches or mm)
H = ZEBRA® height (inches or mm)
Metric (mm)

R =H x 0.01+ 0.10
EwxW1

English (Inches)

R =H x 0.0004+ 0.10
EwxW1

Example: if ZEBRA® is 0.100 /2.54 mm H and 0.030 /0.762mm W, then the maximum resistance on a 0.050 /1.27 mm wide pad will be:

Metric:

R =2.54 x 0.01+ 0.10 = 0.127 ohms
0.762 x 1.72

English:

R =0.100 x 0.0004+ 0.10 = 0.127 ohms
0.030 x 0.050
Nominal Force Deflection Plain ZEBRA® or Insulation Barrier Type

ZEBRA® connectors should be deflected 5% to 25% of H. To calculate F-Force for deflection, use the following formula:

Where:
F = Force (N)

R =H-H1 x 100 (%)
H
H =Height of connector (mm or inches)
H1 =Deflected height of connector (mm or inches)
W =Width of connector (mm or inches)
W1 =Width of ZEBRA portion (mm or inches)
L =Length of connector (mm or inches)

Metric:
F(N) = 9 x D x W x L x 9.8 x 10-3

Inches:
F(N) = 5806 x D x W x L x 9.8 x 10-3

 

Nominal Force Deflection – Silicone Support Type

Metric:
F(N) = [(9 x D x W1 xL) + {2.2 x D x (W-W1) x L}] x 9.8 x 10-3

Inches:
F(N) = [(5806 x D x W1 x L) + {1419 x D x (W-W1) x L}] x 9.8 x 10-3
