Trumonytechs Thermal Conductive Pads

Thermal pads are mainly used between heating components and radiators to improve heat dissipation efficiency.

Thermal conductive pad, also known as thermal conductive silicone pad, is a solution for heat transfer between gaps, it can fill the gaps to complete the heat transfer between the heat generating part and the heat dissipating part.

It is a kind of thermal conductive medium material synthesized by a special process with silica gel as the base material and various auxiliary materials such as metal oxides.It is commonly used on electronic components to achieve the purpose of thermal conductivity, and also can effectively enhance the overall damping performance, so as to achieve good protection performance for electronic components.

Thermal Conductive Pad Advantages

  • The thermal conductive pad we supplied has a wide range of thermal conductivity, the high thermal conductivity 12W/m*K pad already achieved mass production here. Moreover, our thermal conductive pad can be kept for 10 years and remains stable performance.

  • The thermally conductive pad can fill tolerances between the heatsink and the cooling components, thus there’s more flexible craft demand for cooling parts.

  • Thermal conductive silicone pad has good insulation properties, generally up to 8 Kv/mm or more.

  • Another function of the thermal conductive pad is vibration damping and sound-absorbing which can efficiently reduce the noise of machine operation.

  • Thermal conductive silicone pads offer the ease of installation and testing.

Performance of thermal conductive pad

Trumonytechs production and development of thermal conductive mats in performance, structure and thermal conductivity are tested in many aspects, the overall performance are all unique. No matter what your needs are, we can find the right pad for your environment. Choosing the right pad not only provides an excellent thermal interface for the heating element, but also enhances the safety and reliability of the component. We offer thermal conductive mats with the following characteristics:

  • Hardness: The hardness of thermally conductive silicone gaskets is generally measured in Shore 00, the lower the hardness, the lower the compressive stress and the easier it is to displace the air surrounding the metal surface.

  • The relationship between thermal conductivity and thickness: Generally the higher  thermal conductivity, the thinner thermal silicone pad it is. By far the minimum 0.3mm thickness thermal pad can be manufactured in a good qua

  • Voltage resistance: The degree of insulation of thermally conductive silicone gaskets is generally indicated by the breakdown voltage (voltage resistance), which is generally above 10KV/mm for the resin strength of the body.

Installation and Maintenance

Installing Thermal Pads

To optimize the performance of your electronic device, you must install thermal pads correctly. Thermal pads transfer heat between hot components, like the CPU/GPU and battery pack assembly, and the heat sink. They control the device’s temperature and avoid thermal runaway. Below is a basic guide on how to install a thermal pad for optimal performance.

Preparation: Make sure both surfaces (component and heat sink) are clean and free of any old thermal paste or debris. A clean surface improves the effectiveness of the thermal pad.

Measure and Cut: Measure the area where the thermal pad will be used. Cut the pad precisely to fit the area, avoiding any overlaps or shortages that could affect the thermal conductivity.

Placement: Gently place the thermal pad on the component. Most thermal pads do not have adhesive, so it is relatively straightforward to reposition them if required.

Installation: Put the heat sink or element back in place. The pressure from installation ensures good contact. It presses the thermal pad, the element, and the heat sink together.

Remember, a well-installed thermal pad can cut the unit’s temperature a lot. This improves performance and longevity.

Maintenance Tips

Thermal management is an ongoing process and maintaining your thermal pads is key to ensuring continued thermal efficiency. Here are some maintenance tips to help keep your equipment running smoothly:

Regular inspections: Check your thermal pads often. Do this, especially if you notice a temperature increase. Look for signs of wear and tear, such as cracked or hardened pads.

CLEANING: When replacing or inspecting thermal pads, clean the contact surfaces thoroughly. Use isopropyl alcohol for cleaning. It effectively removes old thermal paste and residue without leaving contaminants.

Replacement: Over time, the thermal pads may lose their effectiveness due to continued heat exposure. If you notice significant wear and tear, or if the unit remains hot despite cleaning, it’s time to replace the thermal pad. Use high-quality replacements. Get them from companies such as Trumonytechs. They ensure optimal thermal conductivity.

Good maintenance makes the thermal pad last longer. It also helps the device stay cool and efficient.

Thermal conductive pads have a varied lifespan that depends largely on their material composition and the operational conditions of the device. Generally, a high-quality thermal pad can last anywhere from 3 to 5 years. However, you must monitor your device’s temperature. Inspect the pads often for signs of wear or damage. These issues could show it’s time for a replacement.

Picking the right thickness for a thermal pad is critical. It ensures the best thermal conductivity. The best thickness depends on the gap you need to fill. The gap is between the heat source and the heat sink. A pad too thick might not transfer heat effectively, whereas one too thin might not cover the gap adequately. Generally, thicknesses range from 0.5mm to 3mm. For precise gaps, you can measure the distance between surfaces with a caliper. This can help find the best fit.

Thermal pads and thermal paste conduct heat away from electronics. But, they differ in how they are used and their materials.

Thermal Paste: It is a thick fluid. It fills in tiny imperfections on surfaces. This makes for better heat conduction. It offers higher thermal conductivity than pads and is ideal for components with very tight tolerances. But, it can be messier. It needs careful use to avoid using too much, which can hurt performance.

Thermal Pads: Pre-cut pieces of solid material designed to fill larger gaps with less precision. Pads are easier to use and replace. They are good for less critical tasks or when a quick, clean installation is preferred. They do not conduct heat as well as thermal paste. But, they are enough for many applications that do not need ultra-high conductivity.

The choice between a thermal pad and paste depends on your application’s specific needs. These include the required thermal conductivity, the gap size between the heat source and sink, and your preference for easy and clean installation.
