KITAGAWA INDUSTRIES‘ Thermal Management Materials Meets Miniaturized and Faster Electronic Devices Needs
As electronic devices are becoming more miniaturized and faster, heat issues are put in the spotlight; the devices create high-temperature environments due to high-density design and continuous use. KITAGAWA Industries thermal management products help to lower temperature by conducting and insulating heat, resulting in better performance stability, and durability.
KITAGAWA Industries proposes suitable products with optimal materials, functions, and characteristics according to customers’ requirements and needs.
KITAGAWA Industries offers many kinds of Thermal management materials that have different features. Four Thermal pads are introduced here.
1. Non-Silicone Ultra-Low Hardness Type CPSS
<Features>
· Very soft thermal pad despite being non-silicone
· The pad has excellent adhesion due to good flexibility and stress relief, and therefore it can lower contact resistance.
· It uses non-silicone and creates no siloxane outgassing.
· Unlike silicone pads, the silicone-free pad bleeds hardly any oil and rarely causes problems to peripheral components.
<Applications>
In-vehicle, communication, and AV equipment
<Challenges>
Sometimes, a higher compression ratio of the thermal pad is required due to the components’ dimensional tolerances and gaps between units. However, if the pad has poor flexibility, loads on the heat-generating elements and printed circuit boards (PCBs) are large and may cause device malfunction. In addition, if object surfaces are not even, multiple thermal pads having different thicknesses may be necessary.
<Benefits>
KITAGAWA Industries products have excellent flexibility and stress relief and make the loads lower than the conventional thermal pads. (Since CPSS has high-stress relaxation, it is possible to increase the compression ratio, which allows high dimensional tolerances.)

· COOLPROVIDE (One side tacky)／CPSS-F
2. Non-silicone Highly Thermally Conductive Type CPVT, CPVH
<Features>
· Although it is a non-silicone high-thermal conductivity pad, the hardness is low.
· No siloxane gas is created and less likely to bleed oil compared with silicone type, and rarely causes problems to peripheral components.
<Applications>
In-vehicle, communication, AV and medical equipment, machine tools
<Challenges>
Conventional electrically insulating thermal pads usually have insufficient heat transfer.
High thermal conductivity pads have poor flexibility and stress release.
<Benefits>
KITAGAWA Industries products can lower contact thermal resistance since they possess both high thermal conductivity and low hardness.

· COOLPROVIDE (Both side tacky)／CPVH
· COOLPROVIDE (One side tacky)／CPVH-F
3. Non-silicone Composite Type EMPV
<Features>
· The thermal pad handles both thermal and EMC management. While having the same features as KITAGAWA Industries non-silicone thermal pads, it also suppresses electromagnetic (EM) waves with high magnetic permeability.
<Applications>
In-vehicle and communication equipment, LCD TV
<Benefits>
KITAGAWA Industries unique product helps to solve heat and EMC management issues. The pad can be utilized in limited internal spaces of equipment.
<Non-silicone composite product>
· COOLPROVIDE／EMPV4
4. Ceramic Heat Sink CECD
<Features>
· The heat sink is made of porous ceramic.
· Porous materials have large surface areas and excellent thermal emissivity even compared to metals, resulting in good heat dissipation.
· Around 30% lighter than aluminum
<Applications>
Communication equipment, electrical appliances
<Benefits>
Metal heat sinks may radiate EM waves, however, ceramics are insulators and radiate no EM waves.
