If you have ever disassembled a high-performance power supply or an automotive control module, you might have noticed a material that is thinner than a typical thermal pad, featuring a subtle mesh texture. That is a “Thermal Conductive Silicone Sheet.” Simply put, it is a composite material created by precision-coating silicone elastomers onto high-strength fiberglass […]

1. Physical Definition of Dielectric Constant The Relative Dielectric Constant (εr) is a physical quantity that measures a material’s ability to store electrical energy through polarization. It describes the degree to which a material becomes polarized when placed in an electric field. Mathematical Formula: It is defined as the ratio of the capacitance of a […]

1. Chemical Backbone of Thermal Silicone Thermally conductive silicone is based on polysiloxane (–Si–O–Si–). Each Si atom alternates with O atoms, forming the “Si–O backbone.” The Si atoms are typically bonded to methyl groups (–CH₃) or other functional groups. Basic structure: –Si(CH₃)₂–O–Si(CH₃)₂–O– 2. Bond Angles (Bond Foot) in Si–O–Si In this structure: Si atoms adopt […]

1. Definition of Electronegativity Electronegativity is the ability of an atom to attract shared electrons in a chemical bond. A higher value means the atom is more “greedy” for electrons. The most common scale is the Pauling scale. 2. Periodic Table Trends Electronegativity follows clear trends across the periodic table: Increases from left to right […]

FPC Manufacturing Process Overview Substrate PreparationPolyimide (PI) or PET films are selected as the base material. They are cleaned and dried to ensure a dust-free and oil-free surface. Circuit PatterningCopper is patterned onto the substrate through etching or plating, forming the required conductive traces. Drilling & PlatingHoles are drilled where interconnections are needed, followed by […]
