Our Box Build Assembly Services

We provide a full spectrum of services to satisfy all box build demands. Our engineering team cooperates closely with clients to deliver customized solutions matching unique specifications. From simple electronic enclosures to complex multi-unit rack systems, we manage the whole project. Below is an overview of our service scope:

Product Assembly

Our team converts prototypes into robust, precision box build assemblies. Our technicians replicate your design specifications accurately and deliver finished plug-and-play products within agreed schedules.

Sub-Level Product Assembly

We integrate cables and custom wire harnesses into sub-assemblies. Capable of low to high volume production, we support configurable designs and implement strict testing to meet tight technical requirements.

Automated Encapsulation

Automated encapsulation provides protection for sensitive electronics against moisture, dust and corrosive environments. This treatment improves durability and guarantees stable operation under harsh working conditions.
 

Complete Electro-Mechanical Assembly

We offer comprehensive electro-mechanical assembly to combine electronic circuits and mechanical structures for seamless operation. Services include wiring assembly, hardware fitting and full integration into designated enclosures.

Automated Conformal Coating

Conformal coating protects PCBs from humidity, dust and extreme temperature fluctuations. Our automated coating line delivers uniform, controlled coverage to extend component service life and long-term reliability.

Environmental Testing

We conduct professional environmental testing to simulate real operating conditions. Tests verify resistance to extreme temperatures, humidity and vibration to confirm product reliability across various application scenarios.
 

Complete Product Testing & Burn-In

Functional testing and burn-in screening ensure each unit performs consistently before shipment. We simulate real working loads to validate stable long-term operation and eliminate early failure risks.

Custom Packaging

Custom packaging solutions safeguard finished assemblies during transit. Custom containers and shock-absorbing materials guarantee intact delivery so products arrive ready for deployment.

Software Loading and Product Configuration

We support firmware flashing, software loading and customized system configuration according to client requirements. Pre-programmed units can be directly deployed after delivery to save your commissioning time.
