Printed circuit board quotation system

Abstract

A printed circuit board (PCB) quotation system can estimate corresponding PCB quotations based on various PCB specifications provided by different customers. This allows for a more accurate estimation of the quotations for the PCB specifications provided by customers, solving the problem of large discrepancies between the initial quotation and the price of the delivered product in traditional public board quotations. It also eliminates the problem of time-consuming manual quotation comparison. Therefore, the PCB quotation system can provide accurate and fast quotation lists.
