What thermal pad is used for switching power supply? Switching power supplies have been widely used in today’s various electronic equipment, and their unit power density is also increasing. In order to improve the reliability of switching power supplies, thermal design is an essential link in the design of switching power supplies. If the temperature rise inside the switching power supply is too high, it will lead to the failure of temperature-sensitive semiconductor devices, electrolytic capacitors and other components. When the temperature exceeds a certain value, the failure rate increases exponentially.

A complete thermal design of the switching power supply includes: 1. How to control the calorific value of the heating source; 2. How to dissipate the heat generated by the heating element, so that the temperature rise of the switching power supply is controlled within the allowable range to ensure the switching power supply. reliability.

What thermal conductivity silicone sheet is used for switching power supply? CoolThermo has been deeply engaged in the research and development of thermal conductive materials for more than 10 years, and has accumulated a large number of application solutions for thermal conductive silicone sheets in the switching power supply industry. Recently, a switching power supply manufacturer found the official website of Nuofeng thermal silica gel sheet through the Internet search for “what thermal conductivity silica gel sheet is used for switching power supply”. Looking for a thermally conductive silicone sheet suitable for power switch filling and heat dissipation to reduce interface thermal resistance, the heat generated on the power module substrate needs to be transferred to a certain distance of heat dissipation surface through heat transfer components, and the thermally conductive silicone sheet is required to have high thermal conductivity and flexibility. Good properties, high temperature resistance, aging resistance, high dielectric strength, tear resistance.

After understanding the demands of a switching power supply manufacturer, CoolThermo thermally conductive silicone sheet recommends customers to use the CoolThermo LC300 high thermal conductivity soft thermally conductive silicone sheet based on the successful application solutions in the past, and arranges samples to be sent on the same day. The customer found that the CoolThermo LC300 high thermal conductivity soft thermal conductive silicone sheet can meet the heat dissipation requirements of the company’s power switch module through the sample test of the thermal conductive silicone sheet. Also through this cooperation, CoolThermo sees the ever-changing information of product upgrading in the switching power supply industry. The only thing that remains unchanged is the high requirements for quality and the bottom line of environmental protection, so as to provide users with various types of switching power supplies that are safe and convenient.

CoolThermo LC300 high thermal conductivity soft thermal conductive silicone sheet has a thermal conductivity of 3W/m.k. It is an extra soft, high compression interface gap filling gasket with good flexibility, high temperature resistance, aging resistance, high dielectric strength and tear resistance. and other characteristics, safe and environmentally friendly, and passed UL and ROHS certification; CoolThermo LC300 high thermal conductivity soft thermal conductive silicone sheet can be closely attached to the interface between the surface of the switching power supply chip and the heat dissipation substrate, reducing the contact thermal resistance and improving the thermal conductivity. The material properties of CoolThermo LC300 high thermal conductivity soft thermal conductive silicone sheet determine that it has a good filling effect, especially using a certain amount of compression can make the thermal resistance smaller and the thermal conductivity better, and the material itself has good electrical insulation. effect and shock absorption. Moreover, the use of the thermally conductive silicone sheet is very convenient, it is not easy to lose, and it is convenient for the installation of the heat dissipation module.
