Implementation method and system for rapidly and automatically estimating price of PCB

Abstract

The invention provides an implementation method and system for quickly and automatically estimating the price of a PCB. The method comprises the steps: (1) building project information of PCB processing, dividing the project information of PCB processing into material information and processing parameter information, setting estimation project program codes in a one-to-one correspondence manner, and presetting the price of the project information of PCB processing; (2) operating a PCB processing price estimation interface, automatically analyzing a corresponding estimation item program code, and concluding and analyzing item information of PCB processing of each part; and (3) automatically calling a PCB processing price calculation formula, and obtaining the item information price of PCB processing of each part; and gathering and accumulating the item information prices of the PCB processing of the plurality of parts, and finally obtaining the estimated price of each PCB. The influence of the PCB design change on the price can be evaluated, so that a research and development scheme can be determined; the PCB cost can be controlled to be minimized in the design stage; and a product manager can be helped to estimate the PCB cost.

Description

technical field [0001] The invention belongs to the field of EDA (Electronic Design Automation) PCB design, and in particular relates to a method and system for quickly and automatically estimating PCB prices. Background technique [0002] In the process of PCB board research and development, the product manager needs to estimate the product cost, and the PCB cost is an important part of the product cost. At the same time, the R&D process is a dynamic process of continuous improvement. During this process, the PCB will be upgraded and revised, and there may be changes in shape, stacking, thickness, drilling methods, etc. It is necessary to evaluate the impact of these changes on the cost of the PCB for the development of the solution. Decision-making (such as a certain component on the PCB, the PCB package pins are fine-pitched, and the blind buried hole design must be used, the cost will increase compared with through-hole drilling. Through the comparison of PCB cost estima...

Problems solved by technology

[0003] At present, there is no automatic method for estimating the PCB cost. Only after the PCB design is completed, the PCB board factory can quote afterwards, and the quotations of each board factory are different, which makes it impossible for the R&D and design parties to scientifically and accurately obtain the PCB cost price; or manually One is to calculate the processing price of each part, and then accumulate the total price, which is time-consuming and laborious

Generally speaking, PCB price is an important part of product cost. At present, there is no good estimation method, and we can only passively accept the quotation from the board factory. Due to the lack of quantitative evaluation methods for PCB price, it is impossible to evaluate the impact of PCB design changes on PCB price. Influence, affecting the decision-making of some research and development programs

At the same time, due to the lack of quantitative material information and cost price analysis of processing parameters, it is difficult to minimize the PCB cost in the PCB design stage, especially for mass production of PCB boards, which will increase a lot of PCB board costs
