Silver Connectors

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.

Product Overview

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. 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.

Reliable Surface Alignment and Clamping

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.

Design Recommendations

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.

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:

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:

Our Process

01

Consultation and Coordination

The Customer would put a simple inquiry. A technical Support Engineer would go through the inquiry and generate the necessary drawings through specific dimensions. This would lead to a quote being sent out to the customer for final approval from both B2B parties. 

02

Making Sample Request

If approved, the customer would be able to request a sample of the material that they have requested from the initial Consultation and Coordination. 

03

Order Confirmation

If approval has been completed, an official order would be sent across to Fujipoly Europe B.V. that the Customer Service Department would prioritise to make sure that the order would be completed on time. 

Frequently asked questions

Information about how ZEBRA Connectors work, the benefits, application methods, or safety considerations.

How do you calculate a “slot dimension” in the connector holder?

The volume of the slot should be equal to or slightly greater than the volume of the connector. Consider all tolerances when determining the max volume of the connector. E.g.; Connector H x W x L= Volume

What is Fujipoly America’s UL file number?

Fujipoly’s UL file number is E58126.

What is the “Aspect Ratio” for a Zebra® connector?

A minimum aspect ratio of 1.5 to 1 is recommended. The aspect ration only applies to the Zebra itself and not the optional support material.

What is the compression set of a connector?

Compression set for a plain Zebra (Silver, Carbon, or Low-Temp) is 10% to 15% of the compressed amount. Compression set for a supported Zebra is 30% to 40% of the compressed amount.
