Mechanical testing assesses the physical strength, durability, and structural integrity of electrical and electronic products or their components. It involves applying forces such as tension, compression, impact, vibration, and drop to evaluate how a product withstands mechanical stress during handling, transport, and usage. These tests help identify design flaws, ensure material quality, and verify compliance with safety and performance standards. Mechanical testing is essential to ensure that products can endure real-world conditions without failure, maintaining safety and functionality throughout their lifecycle.
