| Electronics assembly is the fundament of electronics products manufacturing. The design for the electronics assembly process is a kind of tedious, boring, and strong empirical work. In order to improve the efficiency of electronics assembly process, this thesis studied and implemented the electronics assembly process support system.From users, development process and function realization these three aspects, this thesis analyzed the electronics assembly system's demand for the integration technology, completed the overall program structure for the presentation layer, business logic layer and data storage layer of the electronics assembly system, designed single document framework and multi-document framework for the electronics assembly system and given two procedures for operational process within these two frameworks.This thesis studied the key integration technology used in the electronics assembly system. These key integration technologies are: the integration of single document and multi-document framework used to meet the different needs of customers, the integration of electronics assembly system and KM cad used to achieve graphical module, the file-based integration used to deal with a variety of EDA files.This thesis designed user interface and manipulation in VC++ development environment by using MFC, designed business logic layer by using MFC message response mechanism, KM cad graphic processing function and file-based data integration methods, designed data storage layer of the electronics assembly system by using the interface provided by secondary development platform.This thesis completed the electronics assembly system and realized the automated extraction of EDA file information by using KM automation platform. Meanwhile, this thesis further studied the integration of electronics assembly system and PDM, CAPP, etc information system by using DPL scripting language.The electronics assembly system has been applied and got user acceptance. |
