Aerospace & Defence | Conformal Coating, Parylene & ProShieldESD

Mission-Critical Protection for Harsh Environments

Our aerospace & defence conformal coating solutions deliver mission-critical reliability in harsh environments.
Aerospace and defence electronics face some of the harshest operating conditions on earth—and beyond.
At SCH, we apply conformal coatings, Parylene, and ProShieldESD solutions that ensure reliability in extreme
humidity, vibration, salt fog, and altitude. With over 25 years of programme support, we help customers achieve
long-term reliability and compliance with strict industry standards.

For background on industry guidance, see IPC and the
Electrostatic Discharge Association.

Standards & Compliance (IPC / IEC / ESD)

Aerospace & Defence Coating Process

  1. Assessment & Selection: application conditions, qualification needs
  2. Masking & Prep: boots, shapes, tapes, and bake-out
  3. Application: dip, selective spray, or Parylene vacuum deposition
  4. Cure & De-mask: controlled bake or UV cure, remove masking
  5. Inspection & Test: thickness checks, cross-hatch adhesion, ionic tests
  6. Documentation: process validation, travellers, C of C packages

Benefits of Aerospace & Defence Conformal Coating

  • ✅ Extended mission life and reliability
  • ✅ Reduced maintenance and field returns
  • ✅ Compliance with aerospace and defence standards
  • ✅ Lighter than bulky encapsulation
  • ✅ Documented traceability and repeatability

Example Application / Case Study

  • 🎯 Objective: Protect flight-control electronics from condensation and salt fog
  • 🧪 Approach: Applied Parylene C + silicone top-coat, validated with salt-fog & thermal cycling
  • ✅ Result: Passed 1000hr humidity & thermal shock

FAQs

What thickness do you recommend for aerospace coatings?

Typically 25–50µm for liquid coatings; 12–25µm for Parylene. Thickness confirmed with Positector or FM20 optical checks.

Do aerospace coatings meet IPC and defence requirements?

Yes—our processes align with IPC-CC-830, IPC-A-610 Class 3, and customer-specific defence standards.

How quickly can SCH start aerospace coating?

Prototype work can begin within days via subcontract; full in-house programmes are typically delivered within 8–12 weeks.
