The conductive glue bar is commonly known as the zebra bar, which is alternately superimposed by the conductive silicone and insulation silicone.The performance of conductive rubber connector is stable and reliable, and the production assembly is simple and efficient.It is widely used in the connection between the LCD display and the circuit board of game consoles, telephones, electronic watches, calculators, instruments and other products.
Conductive rubber design
When using the foam Type, the H value needs to be more than 0.1mm higher than that of the Silicon intermediate sandwich Type. When using the full insulation Type, the H value needs to be 0.1mm shorter than using the Silicon middle clamp Type.Because the compression ratio has a certain relationship with the material of the Rubber and the characteristics of glass, it should be fully considered when designing.The PITCH selection size of the conductive cohesion (PITCH) conductive gap (PITCH). It is best to consider that each PCB diameter can eat at least 3 carbon layers as the best situation. Generally, the PITCH = PCBPANELPITCH/6 of the conductive rubberEssenceAccording to the actual situation of PCBPANEL, we are currently commonly used: 0.18mm, 0.1mm, and 0.05mm. The smaller the value, the more expensive the price.
How to use conductive adhesive strips
1. When connecting, you need to use a structural part to fix the LCD with the conductive rubber strip and the PCB version.Conductive rubber strips, electrical conductors, and electrical silicon glue strips are commonly known as conductive silicone connectors.2. No welding is required to eliminate damage to thermal device.You can use conductive silicon rubber to connect some heating and damaged electronic components to replace welding.3. It can also replace welding at high temperature and radiation. At this time, conductive silicon rubber not only provides good conductive electricity on the same way, but also makes the connection point in a sealed state to play a role of moisture -proof and corrosion;Display glass; it will not damage the contact surface.
Principle of conductive adhesive
Principle: Form the conductive pathway, so that the conductive glue has conductivity, and the stable contact between particles in the rubber layer is caused by the curbing or drying of the conductive glue.Before curing or drying, the conductive particles are separated in the adhesive, and there is no continuous contact with each other, so it is in an insulation state.After the conductive glue is cured or dry, the volume of the adhesive is caused by the volatilization of the solvent and the curing of the adhesive, and the conductive particles are stable and continuous, which shows the conductivity.
