Thermal management solutions (TMS) are essential for maximising output in electronics manufacturing, since the production process radiates a good amount of waste heat in a very small area

By Belal Khan

Over the years, many new products have been launched to cater to the very intrinsic need of thermal management in electronics manufacturing. These include resins, silicone and non-silicone pastes, heat spreading materials, adhesives, interface pads and tapes. In recent years, silicone is emerging as a good heat absorbing alternative and offers solutions to several challenges faced in electronics manufacturing, apart from providing designers the freedom to explore new styles and applications. With the high integration in the electronics and LED industries, there is greater demand today for better heat-dissipating materials. So materials that exhibit high thermal conductivity and good insulation, have excellent strength even when super thin, and have a low density are getting popular.

Technology trends
For heat-sinks, the technology trends include lighter weight heat-sink materials and more custom shapes. The latter has become possible because of the advances in manufacturing, including 3D printing.
Thermal interface materials (TIMs) are being made much more thermally conductive to enhance the cooling performance of heat-sinks. This includes the addition of highly thermally conductive fillers such as diamond, graphene and silicon carbides.

Products launched in this category

Company: Electrolube Product: SCTP
Launched by Electrolube in November 2015, SCTP is not a standard thermal paste. The surface of the material forms a stable cross-linked system that holds the material in place, even during challenging thermal cycling conditions. However, SCTP does not set to a hard compound and, therefore, can still be reworked easily. Thus, it offers the stability of a cured bonding product with the option to easily rework the unit, if needed. This is ideal for those who are looking to enhance the efficiency of their LED lighting systems or trying to improve the lifetime of the products, especially in challenging conditions.
SCTP is a thermal interface material that’s suitable for the efficient thermal coupling of electrical components. It is specially designed to resist pumping out from the bond line, and can be applied using industrial dispensing equipment or via screen/stencil printing techniques.

New-Thermal-sctp-tcorpKey features:

  • Prevents the pumping out of the thermal interface material
  • Attains high thermal stability
  • Can be readily applied without the need for a solvent
  • Can be used with applications that require high thermal conductivity
  • Enables simple and efficient reworking of components
  • Minimises the outcomes resulting from the mismatch in the coefficient of thermal expansion (CTE)

USP: It is thermally stable, especially during harsh thermal cycles or shock conditions

Company: Electrolube Product: ER2221
ER2221 is an encapsulation resin that is used for protecting driver units. The product was launched in November 2015, and offers both protection from the surrounding environment and efficient heat dissipation in a single package. It has enhanced thermal conductivity and low viscosity to aid potting processes of highly populated and small PCBs. ER2221 is a highly temperature-resistant, thermally conductive, two-part encapsulation compound based on epoxy technology. Designed to meet the increasing demand for efficient thermal dissipation, it combines ease of processing with an enhanced thermal conductivity when compared to traditional thermally conductive encapsulants. It also offers enhanced performance in high temperature applications as well as those subject to thermal cycling.
