Problems solved by technology

[0005] The above-mentioned existing method for measuring the structural data of the medium and copper foil in the PCB board is cumbersome, not only takes a long time but also requires a high cost, and the use of a slicing process to obtain PCB samples from the PCB board will cause damage to the PCB board. Destruction, once sliced, it will not be possible to use this PCB board for repeated measurement of electrical parameters on the board

Abstract

The embodiment of the invention discloses a method for measuring the structural data of a medium and a copper foil in a printed circuit board. Based on a PCB board with copper leakage at the edge of the board, measuring of the data structure of the medium and the copper foil in the PCB board can be realized. The method includes the steps that firstly, the physical structure of a to-be-measured area in the PCB board is copied to the edge of the PCB board, and copper leakage occurs at the edge of the PCB board; then, a treatment procedure before measuring is adopted to pretreat the PCB board edge of the physical structure of the to-be-measured area in a replica board; and then, by measuring the physical structure data of the PCB board edge after pretreatment, the structural data of the medium and the copper foil of the to-be-measured area in the PCB board are obtained. Thus, on the premise of not destroying the structure of the PCB board, the structural data of the medium and the copperfoil in the PCB board are measured, and reuse of test samples can be ensured; and in addition, compared with the prior art, the method reduces the cutting process, greatly reduces the measurement timeconsumed in the measurement process, and improves the measurement efficiency.

Description

technical field [0001] The present application relates to the technical field of storage system hardware design, in particular to a method and device for measuring structural data of medium and copper foil in a printed circuit board. Background technique [0002] In the storage system, the hardware system, as the physical support of the entire system, plays a vital role in the stability and reliability of the system operation. In the entire hardware system, the printed circuit board (PCB), as the physical bearing and interconnection channel of most electronic devices, plays an extremely critical role in the hardware system. [0003] Prepreg (Prepreg, PP) and Core chip are the material components of the PCB board, and their electrical characteristics and thermal stability directly determine the working performance of the PCB board. In the process of manufacturing PCB boards, due to the existence of tolerances in the processing process, the structural data of the dielectric a...
