Zhenbao Trading provides PCBA solutions ranging from smart safety sensors to industrial control boards. Advanced SMT production lines and strict QC processes support OEM and ODM work for buyers worldwide.
Most buyers sourcing boards from China end up managing two relationships — one for components, one for assembly — and absorb the gap between them when something does not fit. We take both sides, so the bill of materials and the finished board sit under one point of accountability.
Work runs from our base in Hangzhou, Zhejiang. That matters for a practical reason: the component supply chain, the assembly line, and the person answering your emails are in the same place, so questions about a part substitution or a test result get answered the same day rather than passed along a chain.
Sensor and alert modules for automotive, childcare, and access-control products, where a missed detection is a safety event rather than an inconvenience.
Build to your design, or adapt one of our existing modules to your specification. Send Gerber files and BOM, or send the functional requirement.
Boards for consumer devices where unit cost and consistency across a long production run both matter.
Control electronics built for continuous operation, vibration, and temperature swings on a factory floor.
Low-volume builds to validate a design before you commit tooling and inventory to a full run.
An in-house module designed for child car seat manufacturers who need latch-status monitoring built into the product rather than bolted on afterwards.
| Function | Real-time detection of seat belt latch status |
|---|---|
| Detection method | Integrated high-sensitivity micro-switches |
| Alert type | Built-in buzzer, immediate acoustic feedback on accidental buckle release |
| Build grade | Industrial-grade PCB materials, rated for vehicle vibration and temperature variation |
| Power design | Low-power circuit design optimised for extended battery life |
| Application | Child safety seats, automotive and childcare OEM products |
| Customisation | Alert behaviour, connector type, and form factor adaptable to your housing |
Not sure whether OEM or ODM is the faster route for your product? Tell us what the board has to do and we will tell you which one gets you there sooner.
Safety-critical sensor modules where detection reliability is a product requirement, not a feature.
Control boards for machinery that runs continuously in dust, vibration, and heat.
Teams moving from prototype to first production run who need one supplier across both stages.
Send your Gerber files and BOM — or just describe what the board needs to do — and we will come back with a quote and a realistic lead time.
