Many factories encounter a common issue during the production and assembly of camera front covers — leakage issues not detected before shipment. Since the front cover seems simple, many assume "water leakage is not a big issue". These seemingly small leaks are often magnified during mass production, leading to returns, warranty claims, and damage to brand reputation. Recognizing and scientifically testing the leak integrity of the camera front cover in advance is the key to avoiding these pitfalls.

Automotive side mirror turn signals are integrated into the exterior rearview mirrors and are used to provide clear directional indications to surrounding traffic participants during turning or lane changes. These lamps typically use LED light sources, offering fast response, high brightness, and long service life. Modern designs seamlessly integrate the turn signal with the streamlined mirror housing, balancing aerodynamics and visual aesthetics, making it an indispensable component of automotive safety and exterior design.

In 2024, a manufacturer failed to carry out systematic leak testing during the mass production of GPS trackers and relied solely on visual inspection before releasing the products to the market. During actual use, due to inadequate enclosure sealing, circuit board corrosion and component failure occurred. In the short term, issues such as unstable positioning signals and frequent disconnections appeared , and later led to a large number of devices becoming completely inoperable. Ultimately, the manufacturer faced large-scale repairs and replacements, resulting in direct economic losses and serious damage to brand reputation and market partnerships
