Electronic Manufacturing Services (EMS)
At HJ Technologies, we provide end-to-end Electronic Manufacturing Services (EMS) designed to support the complete product lifecycle — from prototype validation to large-scale production. As a trusted electronics manufacturing partner, we deliver high-quality PCB assembly and integrated electronic product solutions for diverse industries with varying performance and compliance requirements.
Our manufacturing facilities are equipped with advanced SMT (Surface Mount Technology) and Through-Hole Assembly lines capable of handling both low-volume development builds and high-volume automated production runs. We specialize in assembling complex and high-density PCBs featuring fine-pitch components, BGA/QFN packages, microcontrollers, SMD devices, and multi-layer board configurations. Every assembly process follows controlled workflows including solder paste printing, automated pick-and-place, reflow soldering, wave soldering (if required), AOI (Automated Optical Inspection), manual inspection, and functional testing to ensure long-term electrical stability and product reliability.
Beyond PCB fabrication and assembly, our EMS capabilities extend to:
· Component sourcing and supply chain coordination
· Firmware flashing and device-level configuration
· Box-build and enclosure assembly
· Quality inspection and performance validation
· Secure packaging and shipment
Our engineering and production teams collaborate closely with customers to optimize PCB layout manufacturability, reduce production cost, minimize lead times, and maintain stable supply continuity. We provide detailed manufacturing documentation, traceability records, and compliance support to ensure smooth audits and repeatable build cycles.
HJ Technologies serves a wide range of applications, including industrial automation, IoT devices, renewable energy systems, consumer electronics, telecommunication modules, and automotive-grade subsystems. With a strong commitment to precision, reliability, and scalable manufacturing, we help customers bring robust electronic products to market faster and more efficiently.
