Design principle of conductive rubber connector
| Length (mm) | Height (mm) | Width (mm) | Pitch |
| The glass length reduce 0.5mm | The height between LCD and PCB × (1.08~1.15). In other words, the impression ratio is 8%~15%, and the best impression ratio is 10%. | The edge width of LCD × (0.9~0.95) | 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.

Features
Conductive silicone rubber connector is a conductive component, which is made of methyl vinyl silicone rubber as rubber material, adding conductive fillers and other compounding agents. Use it to connect the LCD screen and the printed circuit, so that the pulse signal is transmitted from the circuit board to the LCD screen through the rubber connector, thereby displaying numbers and various symbols. Circuits connected using conductive silicone rubber connectors have the following significant advantages:
- No welding is required, thereby eliminating damage to thermal devices. Conductive silicone rubber can be used to connect some electronic components that are easily damaged by heat instead of welding. It can also replace welding in high temperature and radiation situations. At this time, conductive silicone rubber not only provides a good conductive electrical path, but also keeps the connection points in a sealed state, preventing moisture and corrosion;
- "Zero impact force" prevents damage to the LCD display glass;
- Will not damage the contact surface;
- Form an airtight seal to protect the printed circuit board from atmospheric corrosion in adverse environments and ensure good connections;
- It has buffering and shock-proof functions;
- Easy to adapt to various contact methods;
- The monitor can be inserted or removed multiple times.
Main categories
- YDP-single-sided foam strip, one side is sponge foam insulation, and three sides have conductive function.
- YL-zebra strip is the most common and commonly used type of conductive strip. It has the function of conducting electricity on all sides.
- YP-double-sided foam strip is also the most common type of conductive strip. There are foam sponges on both sides of the strip, which has good insulation properties.
- YS-transparent sandwich strip. The dark gray transparent silicone on both sides has an insulating function and is relatively harder than other types of strips.
- YI-printed type, this type of conductive tape is characterized by coating a layer of insulating material on the surface of the conductive layer, which will not cause a short circuit with the metal shell when used. When the strip thickness is required to be thin, the maximum conductive layer thickness can be guaranteed.
- QS-insulation strip, the strip is fully insulated. (Commonly used colors include light blue, white, red, and transparent color)
