Deutronic engineers tailor every Custom Automated Test Equipment solution to your specific device under test (DUT). By marrying our modular hardware building blocks with our battle-tested DTS test software, we deliver custom test cells optimized for cycle time, accuracy, and operational ergonomics.
Engineered for high-volume production facilities, Deutronic EoL automated test stations deliver 100% functional verification, electrical safety testing, and automated parameter programming in a single touchless cycle. Designed for automotive electronics, power distributions, and control units.
Specifically developed to validate high-voltage power components (operating up to 900 V DC), this test bench combines high-efficiency programmable load modules, precision power analyzers, and thermal imaging feedback to test DC/DC converters, on-board chargers (OBC), and traction power modules.
Tailored for automotive battery assembly plants and workshop test bays, this automated testing platform validates charge-controller logic, lithium and lead-acid battery management parameters, and plant-wide DC-Connect network interfaces under continuous duty cycles.
Testing advanced sinusoidal commutated speed controllers requires dynamic dynamic-load synchronization. This custom ATE bench measures current waveform fidelity, torque ripple, harmonic distortion, and thermal dissipation under real-time simulated load profiles.
Industrial power supplies operating in harsh intralogistics, AGV, and railway environments demand multi-stress verification. This custom rack automated test system subjects fully potted modules to full-load burn-in, environmental stress screening (ESS), and automated safety limits testing.
Procuring Custom Automated Test Equipment is no longer a localized tooling decision; it is a strategic investment that directly governs manufacturing yield, warranty exposure, and time-to-market. Industrial buyers across North America, Europe, and Asia-Pacific are reshaping their procurement criteria based on four macro trends.
Modern procurement guidelines require ATE vendors to deliver virtual digital twin models of the test bench before physical assembly. Hardware-in-the-Loop (HIL) testing allows software validation long before physical DUT prototypes exist, cutting commissioning time by up to 40%.
With the rapid commercialization of 800V and 1200V SiC (Silicon Carbide) power electronics in commercial e-mobility and grid storage, buyers demand custom ATE platforms equipped with wide-bandgap measurement capabilities, ultra-fast transient sampling, and advanced isolation safety enclosures.
Dedicated single-product test benches are economically obsolete. Procurement strategies prioritize modular matrix fixtures that automatically adjust pinouts, cooling fluid connections, and test limits, enabling a single ATE cell to process dozens of product variants without manual downtime.
Future-proof ATE systems do not merely output "Pass/Fail". They log high-frequency raw sensor data into AI edge-computing models to detect subtle degradation trends, predicting component drift before failures manifest in customer field operations.
The convergence of software-defined hardware, high-density power electronics, and standardized industrial communication protocols is redefining how automated test equipment is engineered.
Hardware provides the measurement muscle, but software defines the system's adaptability. Deutronic DTS test software replaces rigid monolithic code with a modular, parameter-driven environment where test sequences, safety thresholds, and reporting formats are updated dynamically through secure cloud repositories or local plant servers.
As manufacturing footprints contract, bulky external cooling infrastructure and large instrument racks are being phased out. Modern custom test benches integrate contact-cooling thermal management directly into DUT nest fixtures, mimicking real-world automotive and industrial installation conditions.
High-power switching electronics (such as fast-switching GaN and SiC converters) generate severe electromagnetic interference (EMI). Advanced ATE engineering employs optical signal isolation, differential sensing paths, and heavily shielded backplanes to prevent false failures triggered by electrical noise.
To comply with ISO/IEC 17025 traceability guidelines, modern ATE systems perform internal self-checks and relay-matrix verification routines before every shift. Diagnostic software automatically alerts maintenance teams if a pin contact resistance exceeds permissible limits.
For over 35 years, Deutronic Elektronik GmbH has engineered and manufactured mission-critical power electronics and customized automated test equipment at its headquarters in Adlkofen, Bavaria. Operating under strict ISO 9001 and ISO 14001 quality frameworks, Deutronic provides an uncompromised single-source engineering partnership.
Unlike third-party test integrators who assemble parts from disparate suppliers, Deutronic owns the complete value chain: from PCB assembly (SMD and THT), custom transformer winding, and potting technology, to firmware creation, mechanical fixture engineering, and long-term global field support.
Direct answers written by Deutronic senior test automation engineers to assist technical buyers, system integrators, and plant operations managers.
Custom Automated Test Equipment (ATE) is a fully integrated, application-specific testing platform engineered to validate the electrical, mechanical, and functional compliance of electronic assemblies and power components under high-throughput factory conditions. A complete system incorporates custom mechanical contact fixtures, automated pneumatic actuators, safety PLCs, isolated power supplies, electronic loads, bus communications (CAN, LIN, EtherCAT), and automated test management software (such as Deutronic DTS).
Turnkey engineering by a specialized partner like Deutronic eliminates integration bottlenecks. Instead of spending months troubleshooting compatibility issues between separate hardware vendors and custom software code, OEMs receive a fully validated, plug-and-play station built to exact cycle-time, measurement precision, and safety specifications.
Measurement repeatability (Gage Repeatability & Reproducibility) is guaranteed through several engineering layers: 1) Galvanic isolation across all sensing and stimulus channels to eliminate ground loops; 2) Low-noise, custom-designed signal conditioning electronics that filter out factory floor electromagnetic interference (EMI); 3) Precision four-wire Kelvin sensing right at the contact point of the device under test (DUT); and 4) Automated internal calibration references built into the DTS software suite. This combined architecture ensures consistent, drift-free measurement data across thousands of production cycles.
Yes. Flexibility is a core design principle of Deutronic ATE platforms. Our systems feature interchangeable quick-change fixture heads, dynamic pin multiplexing matrix cards, and recipe-based software parameterization. When a new product variant enters the station, the system reads its barcode or RFID tag, automatically loads the matching pin mapping, voltage limits, and test steps in the DTS software, and adjusts mechanical clamping parameters without requiring manual tool changes or line shutdown.
Deutronic Test Software (DTS) features native, industry-standard communication protocols including OPC UA, REST APIs, MQTT, and direct SQL database drivers. DTS can automatically query the plant MES to verify DUT serial numbers and authorization status before starting a test run. Upon test completion, raw time-series measurement curves, pass/fail status codes, operator IDs, and timestamped calibration logs are securely transmitted to the central database, guaranteeing complete 100% component traceability for compliance audits.
Safety is paramount when working with high-voltage DC/DC converters, EV chargers, and power systems. Deutronic custom test cells comply strictly with EN ISO 13849-1 (Performance Level d/e) standards. Safety features include dual-channel safety PLCs, interlocked poly-carbonate safety hoods, light curtains, active ground continuity monitoring, optical status indicators, and automated high-speed active discharge circuits that bleed high-voltage capacitors down to safe SELV levels (< 60V DC) within milliseconds of cycle completion or emergency stop activation.
Because Deutronic manufactures standard hardware modules (DC/DC converters, load banks, power supplies) and maintains an in-house PCB assembly line and standard DTS software codebase, lead times are significantly reduced compared to pure system integrators. Standard custom ATE benches are typically engineered, built, factory acceptance tested (FAT), and delivered within 16 to 24 weeks from final specification sign-off.
Yes. Deutronic operates a global service and support network spanning more than 40 countries, with key regional centers such as Deutronic USA in Duncan, SC. We offer comprehensive Lifecycle Support Agreements that include annual ISO-certified on-site calibration, preventive maintenance, mechanical wear-and-tear replacement (e.g., pogo contact pins), remote software updates, and guaranteed spare parts availability to ensure maximum plant uptime.
Absolutely. Because our development engineering, surface-mount PCB assembly (SMD), mechanical machining, potting, and software integration all take place in-house in Germany, we can cost-effectively execute custom hardware adjustments, specialized enclosure geometries, or dedicated communication protocol plugins even for low-to-medium volume series runs.
