⚡ : conformal coatings facing new challenges
With the rise of electric vehicles, is entering a new era. Higher temperatures, high voltage, increased vibrations, new materials…
Requirements are no longer the same — and neither are the solutions. Today, conformal coatings must go far beyond their traditional role:
✔️ Withstand continuous temperatures up to 150–160°C
✔️ Provide enhanced dielectric insulation
✔️ Maintain adhesion under mechanical stress
✔️ Adapt to increasingly dense hashtag environments
💡 To meet these challenges, two main approaches stand out:
• Silicone coatings (high thermal resistance but sensitive to contamination risks)
• UV LED coatings: -free, ultra-fast curing, and suited for modern industrial processes
➡️ Recent application example to improve PCBA reliability: a hybrid approach combining resin + coating in a single process.
• An ABchimie 80K UV LED resin applied at the base of a sensitive component to absorb mechanical stress
• An ABchimie 836UV LED coating to protect the rest of the board
👉 Results:
✔️ Optimized overall protection
✔️ Targeted reinforcement of critical areas
✔️ Simultaneous curing in just a few seconds
✔️ No additional step in the production line
One step, maximum efficiency.
🔬 With its integrated R&D laboratory, ABchimie supports these new challenges by developing ever more reliable solutions to protect your PCBA.
