Electronic and Electrical Reliability Testing Services

In today's increasingly competitive market, product functions and appearances are no longer the focus of competition among brand enterprises. Instead, product quality and reliability are gaining growing attention from the market and customers.

By using various environmental test equipment to simULate climatic conditions such as high temperature, low temperature, high temperature and high humidity, and temperature changes, we can accelerate potential failures of products in real service environments. This process verifies whether products meet the expected quality targets set during R&D, design, and manufacturing stages, thereby enabling a comprehensive product evaluation to determine their reliable service life.

Xenon Lamp Aging Test

Sunlight is a major factor causing degradation of many materials, including plastics, textiles, coatings, and other organic materials.

The xenon lamp test uses xenon lamps to simulate the damaging effects of full-spectrum sunlight, and spray systems to simulate rain, dew, exposure to direct sunlight, and dark conditions. It is designed to simulate material changes when exposed to sunlight under different environmental conditions.

Test Standards

①　ISO 4892.2

②　GB/T 16422.2

③　ASTM G 155

④　ASTM D 4459

UV Aging Test

UV aging test chambers do not simulate full-spectrum sunlight, but they replicate the damaging effects of solar radiation. This is achieved by confining the main radiation of fluorescent lamps to the ultraviolet band of the solar spectrum.

The test equipment uses UV fluorescent lamps to simulate sunlight, and can also simulate moisture effects through condensation or spraying. It is used to evaluate material changes in terms of color, gloss, cracking, blistering, catalysis, oxidation, etc.

Test Standards

①　ISO 4892.3

②　GB/T 16422.3

③　ASTM G 154

④　ASTM D 4674

Salt Spray Test

Salt spray corrosion is a common and highly destructive form of atmospheric corrosion. This test uses salt spray test equipment to create an artificial simulated salt spray environment for evaluating the corrosion resistance of products or metal materials.

It is divided into two categories: natural environment exposure testing and artificial accelerated simulated salt spray environment testing.

Test Types

①　Neutral Salt Spray Test (NSS TEST)

②　Acetic Acid Salt Spray Test (ASS TEST)

③　Copper-Accelerated Acetic Acid Salt Spray Test (CASS TEST)

④　Comprehensive Salt Spray Test

Temperature and Humidity Test

Temperature and humidity tests are applicable to products that may be used in warm and humid environments. For plastic materials, PCBs, PCBAs, porous materials, or finished products, different materials exhibit varying physical responses to temperature and moisture.

Temperature effects mostly manifest as plastic deformation, overheating, or poor low-temperature startup performance. Porous materials will experience surface moisture adsorption, infiltration, and condensation due to capillary effects in humid environments; in low-temperature environments, static charge accumulation can induce product failures.

Test Items

①　High Temperature | Low Temperature | Constant Temperature and Humidity | Alternating Damp Heat | Rapid Temperature Change | Temperature Shock

Test Standards

Highly Accelerated Life Test (HALT)

HALT (Highly Accelerated Life Testing) is a method that applies step-stress to test samples to identify product defects, operational design margins, and structural strength limits at an early stage.

Defects exposed through HALT cover aspects such as circuit design, manufacturing processes, components, and structures.

Test Items

①　Low Temperature Step-Stress Test | High Temperature Step-Stress Test | Rapid Thermal Cycle Test | Vibration Step-Stress Test | Combined Stress Test

Vibration, Shock & Collision, Drop Tests

Vibration Test

Vibration tests simulate a series of vibration phenomena to verify whether products can withstand vibration environments during transportation or usage throughout their service life, and also to confirm compliance with product design and functional requirements.

Shock & Collision Test

Shock refers to sudden, intense energy release, conversion, and transfer. Shock events have a short duration and occur in a single, non-cyclic process.

Drop Test

Drop tests involve dropping products from a specified height onto a test surface to verify their adaptability to rough handling during transportation.

Test Standards

Three-Comprehensive Test

The comprehensive environmental test combines two environmental stress factors. The effects of the comprehensive environment can more realistically and practically reflect product performance in field applications, and are more likely to expose product defects.

Reference Standards

①　GB/T 2423.35

②　GB/T 2423.36

Gas Corrosion Test

Most products are used in atmospheric environments, where most corrosion occurs. The atmosphere contains corrosive components and factors such as oxygen, humidity, temperature changes, and pollutants.

Reference Standards

①　EJA-364-65

②　GB/T 2423.51

③　IEC 60068-2-60
