IoT wireless hardware PCBA turnkey assembly service

Low power wireless IoT circuit board assembly

Miniaturization: Ultra-Small Form Factor Assembly
We support 01005 passive component mounting and 0.4 mm pitch BGA assembly. HDI PCBs with laser microvias, buried vias and stacked vias meet high-density layout requirements for compact IoT wireless modules.
Low Power Optimization: Extend Battery Service Life
Component placement, copper area design and soldering quality directly influence leakage current. Our engineering team conducts layout reviews and recommends low-power components to help you achieve target battery life for battery-powered IoT equipment.
RF Performance: Professional Antenna & RF Layout Support
Wireless communication performance depends on PCB stackup, ground plane layout and antenna clearance. We review RF circuit layouts before fabrication and optimize stack configuration to improve signal range and reduce electromagnetic interference.
Flexible Scaling: From 1 Prototype to 100,000 Units
Most IoT products start with small prototype batches and quickly expand to mass production. We support the whole product iteration cycle, with consistent production factory, quality management system and dedicated project contact from sampling to volume orders.
