In order to ensure that the silicone insulation gasket is made correctly, the naming specifications need to be as follows:
Preload relationship and curve
The superior elasticity of the silicone insulation gasket can provide reliable reinforcement assistance for the effective connection and sealing of the liquid crystal display module, and effectively avoid the risk of good contact with the components due to the aging deformation of the structural parts and accidental drops during the use of electronic equipment, but with the deformation of the structural parts and the change of compression force, the size of the silicone insulation gasket will also change, and it is necessary to fully consider the structural parts and conductive rubber connectors when setting the structural parts and conductive rubber connectors. As follows:
The calculation of the compressive force of a conductive rubber connector can be calculated by reference to the following formula:
F = Compressive force (g)
E = Modulus of elasticity: 4.4 (MPa)
D = Compression ratio D = (H-H1) ÷H
H = Conductive rubber connector height (mm)
W = Conductive rubber connector width (mm)
L = Conductive rubber connector length (mm)
