Why Do TIMs Break Down at High Voltages?
Thermal / Automotive
Thermal interface materials (TIMs) are commonly used to eliminate air gaps present when an electronic component and its heat dissipating component (heat sink, vapor chamber, cooling pipe, etc.) are mated together. TIMs are typically comprised of two major constituents; the polymer binder, which allows for the TIM to be soft and conformable (necessary to displace air during the assembly process), and the ceramic filler particles, which provide the TIM with a high level of thermal conductivity. While both the polymer binder and the ceramic filler particles are typically electrically insulating, if the TIM is subjected to a high enough voltage differential, electrical current can still short its way through. This phenomenon is known as electrical breakdown, and the voltage at which this breakdown occurs is referred to as the breakdown voltage.

What are the premium requirements of gaskets for flange-to-flange aerospace assemblies such as antennas, access panels, radars and lighting? Electrical conductivity? EMI (electromagnetic interference) shielding? Fluid and pressure sealing? Galvanic corrosion mitigation? In short, the answer is all of these things and more.
For this reason, designers choosing fully-cured, urethane-filled expanded aluminium gaskets will not only find a solution that meets all of these criteria, but one that offers numerous performance improvements when compared with alternative sealing solutions. In fact, users can expect a 33% lower total cost of ownership (TCO) resulting from the avoidance of assembly rework and material replacement.
Can Electrical Resistance Be Used to Predict Shielding Effectiveness?
EMI Shielding
Conductive elastomer EMI shielding gaskets use metallic particles to create a conductive path and shield enclosures from electromagnetic radiation. A key measurement of these gaskets is Electrical Volume Resistivity. Gaskets that have a lower DC resistivity generally indicate a more conductive particle. In many cases, this lower resistance / higher conductivity is associated with better levels of shielding effectiveness. This explains why gaskets with silver particles, which are very conductive, often out-perform gaskets with graphite particles. However, this is not always the case.
