Thermal Pad Solutions

Where the electronic heating element and the heat sink contact, there is a contact gap, which will affect the thermal conductivity, so we usually choose a kind of material that can conduct heat and fill the gap, which is called thermal pad

Thermal pad,In order to solve the contact gap between electronic components and heat sinks or liquid cooling plate, and reduce the contact thermal resistance, our engineers will help you choose the world famous thermal conductivity material suppliers such as 3M,Laird, and we have close cooperation with the engineers of these companies. Usually together to assist customers to choose a reliable and cost-effective thermal pad

Thermal conductivity pad is a high performance gap filling thermal conductivity material, mainly used for the transmission interface between electronic equipment and heat sink or product shell. It has good viscosity, flexibility, good compression performance and excellent thermal conductivity. Make it in use can completely make the air between the electronic element and the heat sink discharge, in order to achieve sufficient contact. The heat dissipation effect is obviously increased.

Thermal conductivity pad has good thermal conductivity and high grade pressure resistance, is to replace thermal grease replacement products, the material itself has a certain flexibility, good fit between the power device and the cooling aluminum sheet or machine shell so as to achieve the best thermal conductivity and heat dissipation purposes, in line with the 21st century electronic industry requirements for thermal materials, It is the best product to replace the binary heat dissipation system of thermal conductive silicon grease and thermal conductive paste plus mica sheet. In the industry, it can also be called thermal conductive silicone sheet, thermal conductive silicone pad, thermal conductive silicone pad, insulating thermal conductive sheet, soft heat dissipation pad and so on

The Metal core printed circuit board

Thermal conductivity pad has certain flexibility, excellent insulation, compressibility, natural surface viscosity, specially designed for the use of gap heat transfer design scheme production, can fill the gap, complete the heat transfer between the heating part and the heat dissipation part, this kind of product can be arbitrarily cut, conducive to meet the automatic production and product maintenance. The process thickness of the silicone thermal insulation pad varies from 0.5mm to 5mm, each 0.5mm plus, that is, 0.5mm 1mm 1.5mm 2mm~5mm, special requirements can be increased to 15mm, specially for the use of the gap heat transfer design scheme production, can fill the gap, complete the heat transfer of the heating part and heat dissipation part, but also play a shock absorption The function of insulation and sealing can meet the design requirements of miniaturization and ultra-thin of social equipment. It is a new material with great technology and usability and is widely used in electronic and electrical products.

Thermal conductive silicone grease is also a kind of filling material, but also has good thermal conductivity, the characteristics of the two materials are compared

1,Thermal conductivity: Thermal conductivity of thermal silicone pad and thermal grease is 1.9-3.0w/m.k and 0.8-3.8w/m.k, respectively.

2,The thermal conductive silicone pad has good insulation performance due to the poor insulation of metal powder added to the thermal conductive silicone grease. The electrical insulation index of 1mm thickness is above 4000 volts.

3,Thermal conductive silicone grease for paste, thermal conductive silicone pad for sheet.

4,Thermal conductivity grease needs to be carefully daub evenly (such as large size is more inconvenient to daub), easy to dirty surrounding devices and cause short circuit and scratch electronic components; The thermal conductive silicone pad can be cut arbitrarily, and the protective film can be torn off and applied directly. The tolerance is small, clean, and labor cost can be saved.

5,As a thermal conductive material for filling gaps, thermal conductive silicone grease is limited, and the thickness of thermal conductive silicone pad varies from 0.5-10mm, which has a wide range of application

6,The same thermal conductivity of thermal conductive silicone grease than soft silicone heat conductive sheet is better, because the thermal resistance of thermal conductive silicone grease is small. Therefore, in order to achieve the same thermal conductivity effect, the thermal conductivity of the thermal conductive silicone pad must be higher than the thermal conductive silicone grease.

7,Thermal grease has been widely used and the price is low. Thermal conductive silicone pads are used in thin and small precision electronic products such as laptops, and the price is slightly higher.
