1. Product Overview

BERGQUIST microTIM mTIM 1028 is a silicone thermoset thin film designed for thermal management in high-performance electronics. It provides consistent thermal conductivity, good durability, and abrasion resistance, even under repeated insertion and removal cycles. With an elastomeric structure, it offers resilience against mechanical stress while delivering improved heat transfer. The product is optimized for optical modules and aluminum or copper heat sink assemblies, supporting reliable performance under demanding conditions.


2. Applications

  • Heat sinks in riding cage assemblies for switches, servers, and routers.

  • Aluminum and copper heat sinks with electroless nickel plating (ASTM B733 Type IV, Class 1, SCO, ≥1 µm).

  • Pluggable optical modules (POMs) requiring robust thermal performance and resistance to abrasion.
