YL Type zebra Connector


I Specifications:

YL Type conductive rubber inter-connector is the compressive conductive rubber, and it is made up with alternative layers of conductive and insulating silicone rubber.


II Applications:

They are widely used in LCD watches and clocks, connect PCB and EL. It can be also used for testing PCB and some conductive testing equipment.

Remark

In order to make the connectors work well, the

compression limit for the height direction of the

connectors must be between 8.0%~15%, and the best

compression value is 10%, and the suitable touch

pressure is bigger than 20g / mm×length.

the best impression

The ratio between

each gold finger

width of PCB and

the conductive

rubber connector

must be more than

3~5.In other words, each gold

finger need touch

3~5 conducting

layer to make

sure good conductive.

Remark: If we have confirmed the height, length, width and pitch of the conductive rubber, but the LCD display is still dark, it means that the resistance is too high, and we need to add the width of conductor to improve.
