PCB stack-up database and design method

Abstract

The invention discloses a PCB stack-up database and a design method. PCB stack-up data comprises the number of PCB card layers, signal layer distribution, thickness, material dielectric constants, loss, resin concentration, glass fiber types, the thickness of each layer of copper foil, wiring impedance, wiring width and wiring distance. The PCB stack-up database provides two user modes: an accessmode which is used for browsing the PCB stack-up data; and an editing mode which is used for maintaining the PCB stack-up database. According to the PCB stack-up database and the design method, through establishment of the PCB stack-up database, existing PCB stack-up is added to the database; through utilization of corresponding screening conditions, a user can solve the problem that in the priorart, the spent time is excessive due to the fact that, for PCB stack-up customization, artificial judgment needs to be carried out; required PCB stack-up types can be rapidly obtained; the PCB customization time is greatly reduced; the PCB customization efficiency is improved; the PCB stack-up customization is simplified; and sufficient sample contrast is provided when the PCB stack-up is selected.

Description

technical field [0001] The invention relates to the technical field of PCB structure design, in particular to a PCB stack structure database and a design method. Background technique [0002] In the process of developing PCA, it is necessary to formulate the PCB stack-up structure. The PCB stack-up structure needs to consider the PCB size, bus type and quantity determined by the system organization, the space occupied by the chip, the space required for the power supply, the number of GPIOs, the space required for the connector, etc. In many aspects, the PCB stack-up structure is determined by the type of board. Most of them require experienced engineers or refer to existing PCBs to make judgments, but it takes a long time to evaluate and verify. [0003] At present, MI engineers usually need to find an Excel template after completing the PCB impedance stack-up design in the pre-production engineering automation software, fill in the simulation results of the pre-production ...
