Today, the thermal conductivity of thermal interface materials film series products have been applied to the control of electrical and electronic products the main board, electronic appliances, auto machinery, mainframe computers, notebook computers, DVD, VCD and any material need to fill and heat dissipation module, its main function is specifically for the use of transfer heat cracks, and insulation, shock absorption, seal, etc.
Steps of correct use of thermal film:
· The first step: keep the contact surface with the thermal conductive silicone sheet clean, use non-depilating cotton cloth to clean the surface of the device (chip and heat sink plate) to prevent the thermal conductive film from adhering to the dirt, the dirty thermal conductive film self-adhesive and sealing thermal conductivity will become worse.
▶ Step 2: Clean the surface of the components (chip and heat sink) with a cotton cloth soaked with industrial cleaner to remove grease and dirt.
· The third step: both sides of the thermal film have protective film, first tear off the protective film on one side of the thermal film, can not tear off both sides of the protective film at the same time, reduce the number and area of direct contact with the thermal film, keep the thermal film self-adhesive and thermal conductivity is not damaged.
▶ Step 4: Tear off the side of the protective film toward the radiator or heat source and align the thermal film with the radiator or heat source first. When laminating the thermal film, we must pay attention to the flatness. The wrinkled thermal film will affect the installation and thermal effect. The thermal conductive film can be used repeatedly to make its installation smooth.
▶ the fifth step: tear off the other side of the protective film of the thermal film, should be light operation to avoid pulling it up to move and being damaged. Aim at the heating source or the radiator and press it gently so that the thermal conductive film is bonded firmly and evenly between the heat dissipation source and the radiator.
▶ the sixth step: thermal film with micro viscosity, radiator installation needs screws or other fixed bonding can be firmly fixed.
