The Chomerics Division of Parker Hannifin Corporation has released its new THERM-A-GAP PAD 30 thermally conductive gap filler pads, a high-performance solution for EV battery packs that fits seamlessly into robotic assembly processes typical of the automotive sector.
Effective thermal management is a priority for EV manufacturers and their supply chain partners. Choosing the optimal TIM for the battery ECU is essential, as EV battery packs generate high levels of heat, and their performance relates directly to internal temperatures.
Cleanliness within the assembly process is another crucial factor in automotive manufacturing, where robots have become increasingly prevalent. They negate the necessity for operators to touch components and inadvertently introduce foreign object debris. Therefore, the selection criteria for any thermal pad solutions must include performance and automation compatibility to error-proof this critical process.
These thermally conductive gap filler pads for EV battery pack applications deliver exceptional performance and conformability at a competitive price. During assembly, vision sensors can see pads which allows effective quality control and fast production. The pads release effortlessly from their liner for pick-and-place robots, making them excellent for high-volume applications, and come in specially designed packaging to ensure safe shipment.
The filler pads provide a soft (34 Shore 00) solution with 3.2W/m-K of thermal conductivity and extremely low outgassing. It ensures an effective thermal interface between heat sinks and electronic devices with uneven surfaces, air gaps, and rough surface textures.
The supporting electrical properties of this RoHS-compliant thermal gap filler pad include: 5.9kVac/mm dielectric strength (ASTM D149 test method); 1013-Ohmcm volume resistivity (ASTM D257); 7.7 dielectric constant at 1,000 KHz (ASTM D150); and 0.001 dissipation factor at 1,000kHz (Chomerics CHO-TM-TP13).
