Telecoms & IoT | Conformal Coating, Parylene & ProShieldESD

Compact, Outdoor & RF-Sensitive Electronics—Protected

Our telecoms & IoT conformal coating and Parylene solutions protect radios, gateways, small cells,
base-station modules, and edge devices exposed to condensation, dust, UV, and temperature swings. We balance
ruggedisation with RF performance—using ultra-thin, uniform barriers that minimise mass and dielectric impact.

For reference frameworks, see IPC, IEC (IEC 60529 IP ratings), the ESD Association (ANSI/ESD S20.20), and ETSI environmental classes (e.g., EN 300 019).

Telecoms & IoT Conformal Coating Challenges

  • ✅ Outdoor exposure: condensation, humidity, UV, and particulates
  • ✅ Temperature swings in cabinets, poles, rooftops, and street furniture
  • ✅ Compact enclosures: tight keep-outs around RF paths, LEDs, and connectors
  • ✅ RF performance: low-Dk, thin protection to minimise detuning and loss
  • ✅ Throughput & traceability for volume rollouts and field service

Telecoms & IoT Conformal Coating & Parylene Solutions

Conformal Coatings for Radio & Edge Devices

Liquid coatings protect logic boards, power stages, and mixed-signal assemblies cost-effectively.

  • ✅ Acrylic – Fast, economical moisture barrier for indoor/outdoor enclosures
  • ✅ Silicone – Excellent thermal cycling and vibration resilience
  • ✅ Urethane/Epoxy – Chemical resistance for urban/industrial atmospheres

Parylene for Antennas, Sensors & Compact RF

Parylene provides uniform, ultra-thin, pinhole-free films that preserve RF paths and fine features.

  • ✅ Minimal RF impact – Thin dielectrics help avoid antenna detuning
  • ✅ True conformality – Edges, vias, cavities, and 3D structures
  • ✅ Grades N/C/D/F tuned for clarity, moisture, and chemical resistance

Telecoms/IoT Coating Process

  1. Assessment & Selection: environment, RF keep-outs, materials & test plan
  2. Masking & Prep: custom boots/shapes/tapes, cleaning, bake-out
  3. Application: selective spray, dip, or Parylene deposition with 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

FAQs

Will coatings affect antenna performance?

Using ultra-thin, low-Dk materials (e.g., Parylene) and careful keep-outs minimises RF detuning. We verify with representative testing when needed.

Can you coat compact IoT devices without blocking LEDs or connectors?

Yes—custom masking (boots/shapes/tapes) preserves indicators, optical windows, and connector interfaces while protecting the rest of the assembly.

What thickness do you recommend for telecoms/IoT boards?

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