Metallographic detection component of flexible circuit board and manufacturing method thereof

Abstract

The invention is applicable to the design field of metallographic detection components of flexible circuit boards, and discloses a metallographic detection component of flexible circuit boards and a manufacturing method thereof. The metallographic detection components of flexible circuit boards include flexible circuit board samples And the sealant encapsulated outside the flexible circuit board sample, the sample hole for metallographic detection is provided on the flexible circuit board sample and along its thickness direction; the metallographic detection component of the flexible circuit board also includes supporting columns and There are at least two rigid support boards, and there are multiple flexible circuit board samples. The stacking directions are respectively set at the first and last ends of the laminated component, the supporting column is penetrated on the laminated component, and the supporting column and the laminated component are encapsulated in the sealing body. The invention solves the problems of low sampling and testing efficiency of the flexible circuit board, low sampling and testing data accuracy and high sampling and testing costs.

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 board (PCB) includes rigid circuit board and flexible circuit board, among them, flexible circuit board (also known as flexible circuit board, referred to as FPC) is a kind of thinner flexible (flexible refers to the object 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 m...
