TAF-Accredited Thermal Characterization Laboratory
Accurate, traceable thermal resistance and thermal impedance data for semiconductors and electronic components, measured with Siemens Simcenter Micred T3Ster.
About the Lab
Founded in September 2017, the EFD thermal characterization laboratory focuses on thermal characterization, thermal resistance analysis and reliability verification of semiconductors and electronic components. The lab holds TAF (Taiwan Accreditation Foundation) accreditation and original-manufacturer certification, and is one of the few distributors in the region operating its own independent thermal lab.
Measurable Devices
LEDs, logic ICs, diodes, discrete and module MOSFETs and IGBTs, SiC / GaN power devices, power modules, and any powered device with a measurable temperature-sensitive voltage.

Core Capabilities
1 · Semiconductor Thermal Characterization
Measuring how well heat escapes from the die.
- Thermal resistance (Rth): junction-to-case and junction-to-ambient
- Thermal transient analysis: non-destructive detection of internal package defects
2 · Automotive Module Lifetime Testing & Failure Analysis
Simulating real operating conditions to find weak points early.
- Lifetime testing: AEC-Q101 / AQG 324 accelerated tests
- Root cause analysis (RCA) with report support
Shared goal: precise measurement data that supports our customers' reliability design and quality verification.
