Laboratory Capabilities

Climatic Environmental Testing 

Climatic environmental testing simulates real climate conditions or reproduces their effects to demonstrate the product's ability to remain intact and functional under specific climatic conditions. The effects on the product may include heat aging, softening, sublimation, expansion, embrittlement, reduced mechanical strength, physical shrinkage, moisture absorption or adsorption, chemical reactions, corrosion, increased conductivity in insulators, leading to product cracking, insulation damage, physical damage, mechanical failure, and increased mechanical stress.

Mechanical Environmental Testing 

Mechanical environmental testing is an effective method for evaluating the resistance of components, parts, and complete systems to mechanical stress in anticipated storage, transportation, and usage environments. The effects on products may include structural damage (e.g., deformation, cracks, or breakage), functional failure (e.g., poor contact, relay malfunction), and process damage (e.g., loosened screws or connectors, solder joint failures).

Testing items and standards:

Combined Environmental Testing 

Combined environmental testing simulates the comprehensive environmental stress that electronic products experience during transportation, storage, and use, reflecting their adaptability to the combined effects of temperature, humidity, and vibration. It exposes product defects and is an essential test for new product development, prototype testing, and product qualification.

Aging and Life Testing 

Aging and life testing simulates various conditions such as high temperatures or harsh environments to evaluate the stability and reliability of electronic products. It is an important process for improving product quality and competitiveness, allowing manufacturers to detect defective items or components, quickly identify issues, and resolve them effectively.

Testing items and standards:
