Welcome to Yiwu Leifeng Electronic Technology Co., Ltd. website
Our thermally conductive silicone sheet products are generally considered to have a service life of 20 years, as they are based on silicone rubber. The lifespan of the thermal conductive sheet is mainly determined by the service life of the silicone rubber.
If you need to solve heat dissipation problems in your actual application conditions, please call our company at +86-579-85680790. Our company will arrange professional sales engineers to solve your problems.
Thermally conductive silicone sheets can be added with adhesive backing. Our company commonly uses 3M 467/9448H and Luxking D502/501/5028/5065 adhesive tapes, but other Brands can be selected as required.
Our company's thermal conductive materials have passed relevant certifications and tests from SGS, UL, and other organizations.
There's no single standard for applying thermal grease, but the key is to apply it evenly, without bubbles or impurities, and as thinly as possible.
There are two main methods for application. One is to apply a small amount of thermal grease to the center of the CPU, a single LED, etc., and then use the pressure of the heatsink to spread it evenly. The other is to spread the thermal grease evenly over the surface of the CPU, a single LED, etc. Another method involves using a steel mesh screen printing process, mainly for large areas and high volumes, but this method results in greater waste.
Generally, if your electronic product design leaves no space for a fan or metal heat sink, you can use a thermally conductive material to directly contact the IC and the casing. This allows heat to be directly transferred to the external cold air via thermal conduction, achieving a cooling effect.
Because metal heat sinks are inherently rigid, uneven installation angles or contact pressure between the heat sink and the IC can prevent efficient heat transfer from the heat source to the heat sink. Adding a thermally conductive, soft material to the interface effectively overcomes this contact problem.
