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

FAQs
Will coatings affect antenna performance?
Using ultra-thin, low-Dk materials (e.g., Parylene) and careful keep-outs minimises RF detuning. Verified with 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.
What thickness do you recommend for telecoms/IoT boards?
Typically 25–50µm for liquid coatings; 10–20µm for Parylene. Final values depend on environment and RF constraints.
