| PCBA (Printed Circuit Board Assembly) cleaning is aerospace electronic product manufacturing, cleaning the important link of the clean degree will directly affect the quality and reliability of electronic products. Most of the current space PCBA by traditional also wash with alcohol sponge on manual cleaning method, cleaning, cleaning efficiency is low by human factors influence the quality greatly.This is based on the above problems, with water cleaning technology of PCB phase cleaning technology as the main research object, and study PCBA cleaning technology, cleaning parameters in similarity calculation method and some key technology, on the basis of the automatic generation of PCBA cleaning parameters difficulties.nowadays, innovative and do the CBR technique combined with PCBA cleaning technology, puts forward example-based PCBA cleaning method to generate parameters, and using VB language Access finished cleaning parameters generated software PCBA design and development. The realization of the management and cleaning parameter database queries. And through the similarity calculation method for all types of software PCB assemblies with automatic generation of washing parameters. Based on the design of a friendly interface, easy operation parameters generated water cleaning PCBA software, effectively solved by technology personnel experience leads to cleaning parameter selection of problems for aerospace water cleaning, provides the reasonable parameter, convenient reference. Eventually applied to practical work, so as to ensure the reliability of electronic product space. |
