Energy & Renewables | Conformal Coating, Parylene & ProShieldESD

Protecting Power Electronics in Harsh, High-Demand Environments

Our energy & renewables conformal coating and Parylene solutions protect inverters, converters, BMS,
chargers, switchgear, and control electronics from moisture, heat, corrosives, and static. We combine robust liquid coatings,
ultra-thin Parylene, and facility-level ESD control to improve reliability, uptime, and safety across solar, wind, grid, and storage.

For reference frameworks, see IPC, IEC (e.g., IEC 60664 insulation coordination), ESD Association (ANSI/ESD S20.20), and safety standards such as UL 1741 / IEC 62109 (project-specific).

Energy & Renewables Conformal Coating Challenges

  • ✅ Moisture, condensation, and salt spray in outdoor and coastal installs
  • ✅ Thermal cycling & hotspots in power modules and cabinets
  • ✅ Chemicals & pollutants (ozone, SOx, cleaning agents, dust)
  • ✅ Preserving creepage/clearance for high-voltage sections (EV, storage, grid)
  • ✅ Throughput & traceability for volume production and field service

Energy & Renewables Conformal Coating & Parylene Solutions

Conformal Coatings for Power & Control Electronics

Standards & Compliance (IPC / IEC / UL / ESD)

Our energy and renewables programmes align with recognised standards and customer specifications:

  • 📘 IPC guidelines incl. IPC-CC-830 and IPC-A-610 (project-specific)
  • 📘 IEC (IEC 60664 insulation coordination for HV design)
  • 📘 UL 1741 / IEC 62109 (safety of power converters) — project-specific compliance
  • 📘 ESD Association – ANSI/ESD S20.20 compliant control programmes

Energy/Renewables Coating Process

  1. Assessment & Selection: environment, HV constraints, materials & verification plan
  2. Masking & Prep: custom boots/shapes/tapes, cleaning, bake-out
  3. Application: selective spray, dip, or Parylene deposition with in-process controls
  4. Cure & De-mask: thermal/UV cure, careful removal, touch-up as required
  5. Inspection & Test: thickness, adhesion (cross-hatch), ionic & visual checks
  6. Documentation: travellers, inspection records, quality packs

Benefits of Energy & Renewables Conformal Coating

  • ✅ Increased reliability and uptime in harsh outdoor conditions
  • ✅ Thin, lightweight protection vs. bulky encapsulation
  • ✅ Better HV spacing support with uniform dielectrics
  • ✅ Documented, traceable processes for audits and compliance

Example Application / Case Study

  • 🎯 Objective: Protect utility-scale inverter control boards from condensation and pollutants
  • 🧪 Approach: Silicone coat on power/control PCBs; Parylene C on sensors/connectors; verified to IEC 60664 creepage/clearance targets
  • ✅ Result: Improved field reliability and reduced corrosion-related failures

FAQs

What thickness do you recommend for energy/renewables electronics?

Typically 25–50µm for liquid coatings; 10–20µm for Parylene. Final values depend on environment, HV spacing, and dielectric targets.

Will coatings affect heat dissipation?

We select chemistries and thicknesses that balance protection with thermal performance; we also keep heatsinks and thermal paths masked and clear.

How do you support high-voltage creepage/clearance?

We design masks/fixtures and selective paths to preserve spacing while protecting critical areas. Documentation and inspection confirm compliance.
