The invention is suitable for the field of designing of a metallographic detection component of a flexible circuit board, and discloses the metallographic detection component of the flexible circuit board and a manufacturing method of the metallographic detection component. The metallographic detection component of the flexible circuit board comprises multiple flexible circuit board sample wafers, an encapsulation rubber body, supporting posts and at least two rigid supporting boards, wherein the sealing rubber body is used for encapsulating the flexible circuit board sample wafers, sample holes which are used for carrying out metallographic detection are formed in the flexible circuit board sample wafers along the thickness direction of the flexible circuit board sample wafers in a penetrating way, all rigid supporting boards and the flexible circuit board sample wafers are stacked in parallel to form a laminating component, the two rigid supporting boards are respectively arranged at the first end and the tail end of the laminating component along the stacking direction of the rigid supporting boards and the flexible circuit board sample wafers, the supporting posts are arranged on the laminating component in the penetrating way, and the supporting posts and the laminating component are encapsulated in the encapsulation rubber body. According to the metallographic detection component disclosed by the invention, the problems of low sampling detection efficiency, low accuracy of sampling detection data and high sampling detection cost of the flexible circuit board are solved.
Description
technical field [0001] The invention belongs to the field of metallographic detection of flexible circuit boards, in particular to a metallographic detection component of flexible circuit boards and a manufacturing method thereof. Background technique [0002] Printed circuit boards (PCBs) include rigid circuit boards and flexible circuit boards. Among them, flexible circuit boards (also known as flexible circuit boards, FPC for short) are flexible with a thin thickness (flexibility refers to the After being deformed by force, the ability to maintain the shape of the deformed force after the force is lost) printed circuit boards are widely used in mobile phones and notebooks due to their high wiring density, light weight, and thin thickness. Computers, digital cameras and other electronic products. [0003] In the production process of printed circuit boards, sampling inspection is an important means to find quality problems in time. The commonly used sampling and testing ...
