SPECIFICATIONS FOR LCD RUBBER CONNECTOR

1. Length : LCD glass lenth-0.5mm

2. Height :

Type L LS LG Height H* x 1.08 H* x 1.10 H* x 1.10 - 1.12 Compression Ration(%) 8 10 10-12

Remarks : (1) H* = Distance from PCB to LCD contact surface.   (2) If height is over 10mm, the compression ration has to be reduced to avoid      bending on connector.

3. Width : The gap of housing x (0.9~0.95)

4. Selection of Pitch : To obtain a better conductivity, 2 to 3 layers of conductors of each pitch on LCD or PCB is recommended. Example : the pitch of LCD is 0.5mm, cnductive width is about 0.3mm Choose connectors with 0.1mm pitch, so there are 3 connectors with the pitch of LCD. the pitch of LCD is 1.0mm, conductive width is 0.5~0.6mm Choose connectors with 0.18mm pitch, so there are 2-3 connectors within the pitch of LCD. the pitch of LCD is 1.5mm, conductive width is 0.75~1.0mm Choose connectors with 0.25mm pitch, so there are 3 connectors within the pitch of LCD Special condition : normally, connector is made of silicone rubber, tilting is very possible during cutting process and would result an angle tolerance around 1o. Hence, a small connector pitch is recommended for a higher connector design. This would creat a better effect of conductivity.

5. Contact spacing : W' Normally W' is 0.4mm If LCD display turned dimly, it means insulation resistance is too high. This can be improved by increasing W' height. Usually W' is 0.4mm, 0.5mm, 0.6mm, 0.8mm......ect. If LS or LG type were selected, the connector's side width has to be 0.3mm minimum for manufacturing concern. Ex : 0.4mm (W')+0.3mm+0.3mm=1.00mm (the minimum height)
