Frequently Asked Questions about Flight Control & Avionics Materials
CAPLINQ provides a range of conformal coatings, encapsulants, and polyimide inks that are engineered for aerospace environments. These materials are selected based on their dielectric strength, thermal stability, resistance to vibration, and compatibility with aerospace substrates such as FR-4, aluminum, and polyimide flex circuits.
How are materials selected for vibration resistance in flight modules?For components like flight computers and sensor modules that experience continuous vibration, materials must provide mechanical damping and maintain adhesion over time. Filled epoxy encapsulants such as LOCTITE STYCAST 2850FT offer excellent vibration resistance and dimensional stability over wide temperature ranges.
What is the recommended conformal coating for aerospace PCBs?HUMISEAL 1B73 is a widely used acrylic conformal coating that provides robust moisture protection while meeting aerospace environmental resistance standards. It cures quickly and is compatible with manual or automated spray processes.
Yes. Many CAPLINQ-supplied materials meet specifications such as MIL-I-46058C, IPC-CC-830B, ESA ESCC, or NASA outgassing standards. For specific documentation or test results, please contact our technical team.
Can these materials withstand high-altitude pressure and thermal cycling?Absolutely. CAPLINQ materials for avionics are formulated for pressure differentials and temperature swings seen in flight profiles. Encapsulants and coatings maintain electrical insulation and adhesion from -55°C to 200°C, making them suitable for both commercial and defense aerospace use.
