| The development of large scale integrated circuits has led to the outbreak of an electronic technological revolution.At present,a variety of electronic products rise one after another in the market,There are some electronic products factory in the market , especially in the gradual expansion of the notebook market.There are some electronic products factory in the market whose main business is OEM has high modern level.The component defect detection system after furnace is an automated optical inspection equipment for these companies to reduce labor costs in production and development.It is a system that can test the mis-placement of high-speed integrated circuit board with various components .When testing ,the circuit board image was taken down by a set of cameras posted on the top of the machine and then transmitted to the component defect detection systems after furnace . The system test the image sended , and finally show the results to the operator for reference on the monitor .The component library is an important part of the component defect detection system after furnace. Component library management system is a application software developed for establishing component library , which provides the function of data conversion, establishing , the edition of standard image and testing boxes.It has the feature of simple operation and easy to use.This topic first introduce the composition of component library, list various types of defects, and analyze the two kinds of test principles. And then analyze the system from the aspects of system requirements, system use cases, and the system module division . Finally describe the design and implementation of the system in detail ,and analyze the algorithm used in functional modules , such as puzzle algorithm, simulated detection algorithm. Component library management system proves to be a good one in the production line,its stability and ease of use have been affirmed by customers. |
