Combining German-rooted power electronics expertise with vertically integrated turnkey contract manufacturing.
From initial circuit layout and firmware design to mechanical enclosure potting and final validation, we manage the entire manufacturing lifecycle under a unified quality system.
State-of-the-art SMT pick-and-place lines combined with manual and automated Through-Hole Technology (THT) assembly ensure military-grade solder joints and precise board layouts.
Our custom DTS software orchestrates complex End-of-Line (EOL) testing sequences, managing multi-variant test beds, parametric data capture, and plant-wide traceability seamless through DC-Connect.
Patented contact-cooling technologies eliminate noisy, failure-prone fans in high-power converters (up to 900V DC), providing vibration-resistant performance in extreme operating environments.
All test fixtures and industrial power modules adhere strictly to CE, UL, ISO 9001, and IATF 16949 standards, engineered specifically to withstand heavy industrial duty cycles.
With localized technical centers across Europe, North America, and Asia, our field service engineers provide rapid commissioning, calibration, and ongoing spare-parts availability.
In modern industrial electronics and electromobility manufacturing, the End-of-Line (EOL) test fixture is no longer merely a mechanical clamp holding a Printed Circuit Board (PCB). It represents the critical intersection between physical signal integrity, thermal management, high-voltage isolation, and real-time data communication. As electric vehicles (EVs) shift toward 800V/900V powertrain architectures and industrial automation demands 99.999% uptime, the engineering requirements for functional test (FCT) and in-circuit test (ICT) fixtures have evolved exponentially.
A high-performance test fixture designed for power electronics—such as DC/DC converters, EV fast charging modules, and motor controllers—must maintain sub-milliohm contact resistance across hundreds of thousands of actuation cycles. Furthermore, it must prevent electrical arcing during high-potential (Hi-Pot) insulation resistance tests while maintaining signal purity for CAN bus, LIN, and Automotive Ethernet telemetry evaluation.
Key Engineering Insight: Conventional off-the-shelf test beds suffer from parasitic inductance and rapid pogo pin degradation when subjected to high-current pulse testing. Advanced OEM/ODM test fixture suppliers must incorporate custom-machined polyoxymethylene (POM) or ESD-safe G10 FR4 carrier plates, micro-aligned spring probes, and integrated liquid or contact cooling blocks within the fixture interface.
When engineering bespoke test fixtures for commercial and automotive electronics, factory teams must account for four major physical and electrical vectors:
To assist procurement managers and lead quality engineers in evaluating supplier capabilities, the matrix below outlines the key benchmark parameters that distinguish standard manual test frames from enterprise-grade automated OEM/ODM test fixtures.
| Technical Parameter | Standard Manual Test Fixture | Advanced OEM/ODM Automated Fixture |
|---|---|---|
| Mechanical Actuation Life | 20,000 – 50,000 Cycles | 100,000 – 500,000+ Cycles (Replaceable Probe Cartridge) |
| Max Operating Voltage | Up to 600V DC | Up to 1,500V DC / High-Isolation Shielding |
| Current Carrying Capacity | Max 15A per probe pin | Up to 350A Continuous (Integrated Busbar Interface) |
| Signal Interface Protocol | Basic Analog / Digital I/O | CAN 2.0B, CAN-FD, SAE J1939, Ethernet, LIN, FlexRay |
| Thermal Management | Passive Convection / Ambient Air | Contact Cooling Plates / Integrated Air Jets |
| Software Integration | Stand-alone Manual Logger | Native DTS Software Suite / Factory MES Traceability |
| Fixture Changeover Time | 15 – 30 Minutes (Manual Screws) | < 60 Seconds (Zero-Point Fast Locking System) |
The global shift toward electrification across transport, logistics, and renewable infrastructure has fundamentally altered how industrial enterprises procure test equipment and OEM power modules. Procurement teams are moving away from fragmented vendor sourcing—where fixtures are bought from one shop, software from another, and power electronics from a third—toward a unified System Supplier Paradigm.
Dedicated single-product test fixtures are rapidly becoming economically obsolete. Modern manufacturing lines produce multiple model variants—such as 20kW, 30kW, and 40kW EV Wallboxes—on the same assembly line. Leading OEM/ODM suppliers now engineer modular test bases where interchangeable adapter cassettes (fixture beds) can be swapped in under one minute. This drastically reduces capital expenditure (CapEx) and minimizes downtime during product line retooling.
In high-throughput EV charger production, a single failed probe pin can cause false-negative test results, halting an entire production shift. Next-generation test fixtures embed wear-counting sensors, contact-resistance monitoring circuits, and pneumatics pressure transducers directly into the fixture assembly. These sensors feed real-time diagnostic telemetry into the plant’s DTS software, alerting maintenance technicians to replace specific pogo pin cartridges before probe degradation impacts yield.
To reduce supply chain fragility, global enterprise buyers are increasingly demanding vertically integrated ODM partners who provide comprehensive electronic contract manufacturing. Partnering with a manufacturer that controls PCB assembly (SMD and THT), potting, mechanical metal fabrication, and automated test system creation under one roof guarantees seamless compatibility between the unit under test (UUT) and the test equipment itself.
