【摘要】：實裝電路板PCBA作為現(xiàn)代電子設備的重要組成部分,其生產質量直接影響到產品的功能和性能。目前工廠對PCBA的生產品質檢驗工作大部分由人工完成,檢測過程中因人為因素的影響,常常發(fā)生誤檢、漏檢等問題,并且檢測效率低下。本文研制了一套針對MSP430硬件工具PCBA的專用自動測試系統(tǒng),功能包括程序燒寫,電壓檢測,晶振檢測,通訊檢測,硬件通路檢測,FLASH檢測,FRAM檢測,EEPROM檢測,設備ID獲取,測試信息記錄等。本文主要工作內容包括：測試系統(tǒng)檢測電路硬件設計；測試系統(tǒng)主控程序設計；四類MSP430硬件工具測試下位機程序編寫；基于Visual Basic的PC上位機軟件開發(fā)；測試治具架構設計。本文的工作重點在于測試系統(tǒng)硬件電路的設計和測試程序的編寫；難點在于根據四類MSP430硬件工具的工作原理設計相應的檢測項目。本文已成功實現(xiàn)了測試系統(tǒng)的各項自動檢測功能,且兼容四類MSP430硬件工具的檢測,并已成功應用于工廠的生產測試流水線上,大大提高了工廠的檢測效率,降低了人力資源成本,為工廠節(jié)省了開支。
[Abstract]:As an important part of modern electronic equipment, the production quality of real circuit board (PCBA) directly affects the function and performance of the product. At present, most of the production quality inspection of PCBA in factories is done by manual work. Due to the influence of human factors in the inspection process, problems such as false detection and missed inspection often occur, and the detection efficiency is low. In this paper, a special automatic test system for MSP430 hardware tool PCBA is developed. Its functions include program writing, voltage detection, crystal oscillator detection, communication detection, hardware path detection, flash detection, FRAM detection, EEPROM detection, equipment ID acquisition, etc. Test information record etc. The main work of this paper includes: testing circuit hardware design of test system; main control program design of test system; programming of four kinds of MSP430 hardware tools to test lower computer; PC host computer software development based on Visual Basic; structure design of test fixture. The emphasis of this paper is on the design of the hardware circuit of the test system and the writing of the test program, and the difficulty is to design the corresponding inspection items according to the working principle of the four kinds of MSP430 hardware tools. This paper has successfully realized all the automatic testing functions of the test system, and is compatible with four kinds of MSP430 hardware tools, and has been successfully applied to the production test pipeline of the factory, which greatly improves the efficiency of the factory testing. Reduce the cost of human resources and save money for the factory.
