NexPCB helps Industrial IoT innovators accelerate product development — from sensor nodes and edge gateways to environmental monitoring and industrial wearables — with end-to-end engineering, manufacturing, and global certification support.
Manufacturing for IIoT products — IP67/IP68 sealing, 300h+ salt spray testing, thermal management, and precision mechanical production.
Fully sealed enclosures designed for outdoor and harsh-environment deployment. We have in-house air leakage testing equipment that can verify up to IP68-standard conditions — whether it's rain, dust, or submersion, your device keeps working.
Industrial-grade thermal design with conformal coating, high-Tg substrates, and thermal management engineering. Built to maintain performance in both freezing cold and scorching heat — typical of IIoT field deployments.
EE: Aging, Temp Cycling, Vibration, ESD, Surge. ME: Drop test (1.2m), Salt spray (24–48h standard, up to 300h+), Button life cycles, Silk screen adhesion, UV resistance, High-temperature aging, Flame retardant testing — most reliability verification done before formal certification submission.
Magnesium & aluminum alloy die-casting, single-color and double-shot injection molding, CNC machining, metal stamping, and post-processing including painting, laser engraving, and silk screen printing — covering the full mechanical production chain.
NexPCB supports key stages of hardware development — from DFM review, EE design and PCBA assembly to ME prototyping, multi-stage validation, and volume production.
From MedTech to mobility — domain experience across industries with demanding hardware requirements.
Patient monitors, diagnostic sensors, wearable health trackers, insulin pump controllers
Smart grid sensors, solar monitoring, battery management systems, EV charging hardware
Vision-guided robotic arms, autonomous mobile robots, edge AI inference modules
Smart home hubs, environmental sensors, connected appliances, IoT security devices
Telematics units, fleet tracking, battery diagnostics, V2X communication modules
A single partner across the full product lifecycle — streamlined coordination from concept through end-of-life, designed to reduce complexity at every stage.
Business model analysis, technology architecture review, and budget planning for hardware startups and teams validating product-market fit.
Rapid prototyping, EVT/DVT verification, supply chain build-out — moving from concept to engineering-valid prototype in weeks, not months.
End-to-end manufacturing — mold development, quality control through key stages, and global logistics from pilot run to volume production.
Continuous supply chain management, field repair programs, EOL transition and spare parts planning — the long-term partnership most manufacturers don't offer.
The projects below represent a range of IIoT hardware categories where NexPCB has provided end-to-end manufacturing support.
High-precision satellite positioning receivers for surveying, agriculture, construction, and drone applications. Multi-band GNSS antenna integration with BGA packaging and low-power wireless communication.
Remote server management and data center operations hardware. High-definition video capture, HDI multi-layer PCB, PoE power integration — manufactured in Southeast Asia for tariff management.
Industrial-grade communication gateways and computing platforms using ARM-based SoCs. Operating at wide temperature range, with BGA high-density packaging and modular standard interfaces.
Patented retrofit condition monitoring sensor with ultra-low-power wireless communication and long-life battery design. Validated by major industrial OEMs — progressing from prototype toward mass production.
Industrial mmWave radar module with high-frequency RF design, BGA RF package, HDI high-frequency PCB, and FPC flexible interconnect. Multiple hardware revision cycles over several years of iterative development.
Multi-parameter soil monitoring sensors for smart agriculture — measuring moisture, temperature, and electrical conductivity. Designed for long-term outdoor operation in harsh agricultural environments with conformal coating protection.

From your first idea to production-ready design — every step includes your engineering team.
Deep-dive into your application environment, connectivity needs, power budget, certification targets, and volume plan.
EE/ME co-design — schematic, PCB layout, enclosure, thermal analysis — typically reviewed with your team before first article.
EVT/DVT/PVT milestones with AOI, X-Ray, functional test JIGs, burn-in, and pre-compliance scanning — before formal certification submission.
Production ramp, global logistics, and lifecycle management — from 5-piece prototype to 5,000+ units per month.
The questions we hear most from engineering leads evaluating manufacturing partners.
Whether you're at the prototype stage or ready for mass production, NexPCB's turnkey manufacturing platform is built for hardware innovators.
