Description

Technical Field

[0001] The present invention relates to the technical field of flexible printed circuit board detection, and particularly to a flexible printed circuit board detection device. Background Art

[0002] With the continuous miniaturization and functionalization of electronic products, flexible printed circuit boards (FPCs), as key connecting components, have been widely used in modern electronic products. Due to their bendable, thin, and high-density integration characteristics, flexible printed circuit boards are widely used in fields such as smartphones, tablets, wearable devices, and automotive electronics. However, due to the material properties and production process complexity during the production of flexible printed circuit boards, quality problems such as dimensional deviation, appearance defects, and conductivity issues are likely to occur. These defects may lead to functional failures or shortened service lives of the final products. Therefore, it is particularly important to perform high-precision detection on flexible printed circuit boards.

[0003] Existing flexible printed circuit board detection technologies mainly focus on single detection methods, such as dimensional detection, appearance defect detection, and conductivity detection, etc. However, in actual applications, the production environment and usage environment of flexible printed circuit boards are complex and variable. Single detection means often cannot comprehensively cover all potential problems, and the detection efficiency is low. Especially in extreme environments such as high temperature, low temperature, and hot and cold alternation, traditional detection methods are difficult to effectively evaluate the reliability and stability of flexible printed circuit boards. Therefore, there is an urgent need for an efficient detection device that can comprehensively perform appearance detection, environmental adaptability detection, and conductivity testing to ensure the quality and performance of flexible printed circuit boards. Therefore, the present invention provides a flexible printed circuit board detection device. Summary of the Invention
