Interface and Sealing Solutions

Boyd provides engineered materials that ensure efficient heat transfer, system protection, and long-term reliability in harsh aerospace, space, and defence environments. Thermal Interface Materials (TIMs) enhance conduction between components and cold plates; EMI/RFI shielding protects sensitive payloads from electromagnetic interference; and seals, gaskets, and vibration isolators maintain system integrity under vacuum, launch loads, and extreme temperatures. These solutions safeguard electronics, extend operational life, and guarantee mission success.

• Thermal Interface Materials (TIMs) – Gap fillers, pads, and greases to ensure efficient heat transfer between components.mprove conduction between heat-generating components (e.g., processors, power amplifiers) and heat spreaders/cold plates.

  Types: Gap fillers, pads, greases, phase-change materials, graphite sheets.

  Advantages:
