"Burn-in testing" ensures the reliability and durability of hardware products by identifying potential defects before they reach consumers. This process involves operating equipment for an extended period under normal and extreme conditions, allowing manufacturers to spot failures early in the product lifecycle. By subjecting products to rigorous testing, companies can enhance product quality, minimize returns, and boost customer satisfaction. Ultimately, burn-in testing is vital for ensuring that devices meet performance standards and operate as intended when used in real-world scenarios.
