In modern electronic product development—whether for consumer devices, automotive modules, industrial control units, or smart IoT systems—electrical behavior defines functional performance, safety, and lifetime reliability.
At EXPERTA | TESTING, we support manufacturers, designers, and material developers with an integrated suite of electrical material and product property assessments.
This capability overview highlights our expertise across material-level electrical characterization and product-level compliance and reliability testing, providing both fundamental insights and actionable data to guide engineering decisions.
Electrical Material Property Testing
Dielectric Analysis (DEA)
What it is: Measurement of dielectric behavior such as permittivity and loss factor over frequency and temperature.
Example: Evaluating dielectric stability of polymer housings used in compact consumer electronics.
Seebeck Coefficient Analysis
What it is: Determination of the thermoelectric voltage generated across a material under a temperature gradient.
Example: Characterizing filled polymer composites used in energy-harvesting system components.
Electrical Conductivity (High Temperature)
What it is: Measurement of electrical conductivity under elevated thermal conditions.
Example: Assessing conductivity drift in polymer composites reinforced with conductive fillers.
DC Potential Drop Testing
What it is: Evaluation of resistive behavior by analyzing voltage drop under constant DC load.
Example: Verification of uniform current distribution in busbar materials.
Breakdown Voltage Testing
What it is: Determination of the voltage at which a material electrically fails.
Example: Ensuring insulation materials meet high-voltage safety requirements.
Product-Level Electrical Testing & Compliance
Consumer & Industrial Electronic Compliance Testing protects the users by ensuring products meet strict safety, performance, and reliability standards.
It reduces risks like electrical hazards, interference, and product failures.
By verifying quality before market release, compliance testing increases consumer confidence, supports fair competition, and helps ensure long-lasting, trustworthy electronic devices in everyday life.
Consumer & Industrial Electronic Compliance Testing
What it is: Verification of compliance with regional and global electrical safety standards.
Example: Certification support for mass-market appliances.
EMC – Electromagnetic Compatibility Testing
What it is: Evaluation of emission and immunity performance under regulatory requirements.
Example: Verifying that a new smart-home device meets CE/EMC standards.
Product Performance & Reliability Testing
What it is: Combined environmental, electrical, and mechanical stress validation.
Example: Long-term reliability qualification of industrial control electronics.
IP – Ingression Protection Testing
What it is: Verification of resistance to dust and liquid penetration according to IP standards.
Example: Assessing watertightness of handheld consumer devices.
OP – Operating Point Testing
What it is: Validation of electrical operating limits within specified voltage, current, and thermal boundaries.
Example: Confirming safe operation of power modules in industrial equipment.
JTAG Boundary Testing
What it is: Digital boundary-scan testing for verifying PCB connections and logic behavior.
Example: Identifying assembly faults in high-density consumer electronics boards.
Power Analysis
What it is: Measurement and analysis of energy consumption, power profiles, and efficiency.
