ETAC Testing Corse

Automotive Testing

Automotive environmental testing that supports the reliability of all electronic components

Modern automobiles are equipped with more than 100 ECUs and semiconductor devices per vehicle. From engine control to ADAS (Advanced Driver Assistance System), numerous electronic components work together, and reliability is required to ensure reliable operation even under harsh environmental conditions such as temperature, humidity, vibration, and shock. ETAC's environmental test facilities can reproduce actual driving environments to comprehensively evaluate the durability, quality, and safety of electronic components and in-vehicle devices.

Advantages of hiring ETAC

1. one-stop testing for a wide variety of tests

We have a system in place to conduct multiple environmental load tests such as temperature, humidity, vibration, shock, and corrosion all at once. We also have a large environmental testing room where tests can be conducted not only on parts and in-vehicle components, but also on vehicles themselves, allowing us to flexibly respond to complex environmental conditions and streamline our development schedule.

2. knowledge of a wide range of in-vehicle devices

We have experience in all areas of evaluation, from engine ECUs to communication modules, ADAS cameras, and EV batteries, and can propose optimal test conditions.

3. reliability assessment of compliance with international standards

We provide quality evaluations based on international standards such as ISO/JASO/IEC/UN/ECE for export-oriented in-vehicle equipment.

4. high accuracy data and rapid reporting

Strict measurement of temperature and humidity control accuracy, vibration frequency control, etc. Test results are quickly reported in graph and CSV format for immediate use in design improvement.

5. support from the early development phase to the mass production phase

We propose step-by-step test plans according to the development process, from material evaluation at the prototype stage to mass production reliability of the final product.

6. testing system with global network

In addition to major cities in Japan, we also have testing bases in ASEAN countries. We can seamlessly handle testing for overseas manufacturing and export.

Typical Environmental Test Menu

High temperature storage test (HTS)

High Temperature Storage (HTS) is a test that evaluates the service life, performance degradation, heat resistance, and long-term reliability of products and materials in a short period of time by intentionally accelerating aging through prolonged exposure to high temperatures.

Low temperature storage test (LTS)

Low Temperature Storage (LTS) is a test that evaluates the service life, performance degradation, heat resistance, and long-term reliability of products and materials in a short period of time by intentionally accelerating aging through prolonged exposure to low temperatures.

High temperature operating test (HTO)

High Temperature Operating (HTO) Test is conducted to accelerate the degradation of products and materials by continuously applying voltage and current while exposing them to high temperatures. It is used to detect defects and to verify reliability and durability.

Low temperature operating test (LTO)

Temperature Cycling Test (TCT)

Temperature Cycling Test (TCT) is conducted to evaluate the durability and reliability of products and materials by alternately exposing them to high and low temperatures.This process accelerates degradation and failures caused by thermal expansion and contraction due to temperature changes.

Thermal shock test (TST) liquid bath type

Thermal Shock Test (Liquid Bath Type, TST) is conducted to detect and evaluate early defects and weaknesses such as cracks, delamination, and deformation by alternately immersing products and materials in hot and cold liquids to impose extreme temperature changes.

For environmental testing of automotive components and in-vehicle equipment,Scientific approach to assure safety, reliability, and long-term qualityThis is the first time that we have conducted a test of our products. We combine a variety of tests to verify that our products can perform in all usage environments around the world, supporting the peace of mind of next-generation mobility.
