EMS (Electronic Manufacturing Services) is a critical partner for tech companies looking to streamline product development and manufacturing. OPCBA’s ODM/EMS service delivers end-to-end support, resolving technical challenges quickly through an experienced engineering team. Our services span embedded system development, hardware and software design, qualification testing, and system integration—helping you bring products to market faster and more reliably.
1. Core ODM/EMS Capabilities
Our full-service product development covers every stage of the lifecycle, with expertise in:
- System Design: Architecture planning, electronic circuit design, and real-time software development
- User Experience: Graphical user interface (GUI) and tool development for intuitive product interaction
- Hardware Design: Printed circuit board (PCB) layout, enclosure design, and packaging optimization
- Embedded Expertise: Development on microprocessors and microcontrollers from Freescale, Infineon, Intel, Texas Instruments, and Microchip
- Software Development: High-level and low-level coding, model-based design, and automatic code generation
- Pre-Validation: EMI testing and environmental application assessments to mitigate production risks
Upon project completion, you receive full documentation, including design schematics, BOMs, and test reports.
2. Key EMS Service Experience
Our ODM/EMS track record spans complex electronic systems, including:
- Analog and digital sensor integration
- Core processor design and optimization
- Closed-loop control systems (sensor and sensorless)
- Brushed/brushless AC/DC motor controllers
- Power supply and battery management solutions
- Multi-channel communication link development
- Distributed process control and diagnostic systems
To ensure traceability, we use a configuration management system to track hardware and software version changes. This supports full lifecycle management—from prototype to mass production—for applications in industrial control, IoT, medical devices, aerospace, and telecommunications.
3. DFM: Reduce Manufacturing Risks Early
As part of our EMS offering, we provide free DFM (Design for Manufacturability) checks for PCBs. This service optimizes your design for production accuracy, minimizing risks before mass manufacturing. Our DFM checklist includes:
- Document version control and process validation (lead/lead-free)
- Clear component labeling and silk screen verification
- BOM alignment with PCB pad design
- Layer stackup and panelization optimization
- SMT stencil and test fixture validation
- Humidity-sensitive component protection planning
By identifying defects during prototyping, we reduce rework costs and accelerate time-to-market.
4. Reliable Electronic Component Procurement
Our EMS service includes a robust supply chain management system to ensure genuine, high-quality components:
- Supplier Qualification: Strict audits and sample validation for all partners
- IQC Inspection: AQL sampling and lab testing for core components
- Pricing & Supply Security: Centralized procurement with 10+ year partnerships for competitive pricing and priority supply
- Inventory Efficiency: Reduces your overhead by eliminating in-house purchasing, inspection, and storage costs
This turnkey procurement model lowers your total cost of ownership and improves cash flow.
5. End-to-End Electronic Assembly
We offer complete finished product assembly as part of our EMS capabilities, supporting industrial controllers, consumer electronics, IoT modules, and more. Our process includes:
- PCB Assembly(PCBA) Integration: Combining tested circuit boards with enclosures, wiring, and motors
- Quality Control: 100% online QC inspection, QA spot checks, and pre-shipment OBA audits
- Traceability: Barcode tracking for full product lifecycle visibility
- Process Expertise: SOP compliance, torque control, an d precision tooling for consistent results
With a 95% skilled workforce and real-time defect analysis, we achieve industry-leading assembly pass rates.
6. Environmental & Reliability Testing
To ensure product durability, our EMS service includes aging testing and environmental validation:
- Aging Tests: 72-hour to 7-day simulated operation under controlled temperature/humidity
- Reliability Checks: Drop, vibration, and salt spray testing (via partner labs for specialized needs)
- Data-Driven Improvement: Performance data analysis to refine production processes
This ensures your products meet strict quality standards for long-term field reliability.
