Industrial & Electronics | Conformal Coating, Parylene & ProShieldESD

Uptime, Reliability & Compliance in Harsh Facilities

Our industrial electronics conformal coating and Parylene solutions protect PLCs, drives, sensors, HMIs,
and control modules against dust, moisture, chemicals, and temperature swings. We combine robust liquid coatings,
ultra-thin Parylene, and facility-level ESD control to raise MTBF, stabilise yield, and support audit-ready documentation.

For reference frameworks, see IPC,
IEC,
ISO 9001,
and the ESD Association.

Industrial Electronics Conformal Coating Challenges

  • ✅ Coping with dust, moisture, and corrosive atmospheres (process lines, washdown)
  • ✅ Maintaining reliability under temperature cycling and equipment vibration
  • ✅ Managing mixed chemistries and cleaning agents around electronics
  • ✅ Preserving creepage/clearance on compact control boards and power stages
  • ✅ Ensuring throughput, traceability, and audit-ready documentation

Industrial Electronics Conformal Coating & Parylene Solutions

Conformal Coatings for Control & Power Electronics

For drives, PLC I/O, HMIs, and power modules, liquid coatings offer proven protection and scalable throughput.

  • ✅ Urethane / Epoxy – Strong chemical resistance in harsh atmospheres
  • ✅ Silicone – Thermal cycling and vibration resilience for power electronics
  • ✅ Acrylic – Cost-effective moisture barrier with fast processing

Parylene for Sensors, MEMS & Compact Assemblies

Parylene provides ultra-thin, uniform coverage where space, weight, and fine features make liquid options difficult.

  • ✅ Uniform, pinhole-free barriers over edges, cavities, and complex 3D geometries
  • ✅ Thin dielectric layers help preserve creepage/clearance on dense boards
  • ✅ Grades N/C/D/F tuned for clarity, moisture, and chemical performance

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

Our industrial programmes align with global standards and quality frameworks:

  • 📘 IPC guidelines incl. IPC-CC-830 and IPC-A-610 (project-specific)
  • 📘 IEC frameworks (e.g., IEC 60664 insulation coordination)
  • 📘 ISO 9001 quality management and documentation control
  • 📘 ESD Association – ANSI/ESD S20.20 compliant control programmes

Industrial Coating Process

  1. Assessment & Selection: environment, risks, keep-outs, materials & verification plan
  2. Masking & Prep: 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 Industrial Electronics Conformal Coating

  • ✅ Higher MTBF and reduced unplanned downtime
  • ✅ Robust protection from moisture, dust, chemicals, and corrosion
  • ✅ Lightweight, space-efficient alternative to encapsulation
  • ✅ Consistent, traceable processes for audits and customer specs

Example Application / Case Study

  • 🎯 Objective: Protect VFD control boards in a chemical-processing plant
  • 🧪 Approach: Urethane conformal coat for chemical resistance; Parylene on sensors/MEMS; verified to IEC 60664 creepage/clearance targets
  • ✅ Result: Fewer corrosion-related failures; improved uptime and audit compliance

FAQs

What thickness do you recommend for industrial electronics?

Typically 25–50µm for liquid coatings; 10–20µm for Parylene. Final thickness depends on environment, keep-outs, and dielectric targets.

Can coated boards be cleaned or reworked?

Yes—processes allow controlled cleaning and rework; stripping methods (e.g., micro-abrasion, solvents, or thermal/mechanical) are selected per chemistry.

How do you document quality and traceability?

We provide travellers, inspection data (thickness/adhesion/ionic), and certificates aligned with ISO 9001 practices and customer specs.
