| dc.description.abstract | In the electronic industry of our country, Surface Mount Technology (SMT) is the main technique used in the manufacturing of 3C products. In the early stages, before the advent of SMT technology, manual insertion of components was the primary method. Later, dedicated SMT components were developed to meet the requirements of automated SMT placement equipment. At that time, Automated Optical Inspection (AOI) devices were not available, and visual inspection relying on human labor was the only method used. As SMT components became smaller and denser, the use of magnifying glasses became necessary for inspection. However, manual quality inspection is prone to errors and omissions. AOI inspection equipment was introduced to overcome this problem.
The initial AOI inspection equipment was limited to 2D AOI (introduced in 1996). Although it allowed real-time quality control, its high rate of false judgments required manual rechecking for each AOI device. In 2015, the introduction of 3D AOI inspection equipment finally freed AOI inspection devices, which had been in development for over thirty years, from reliance on human labor, achieving high detection rates and high yield rates through complete automation.
In addition, process improvement in SMT production lines is a critical engineering task. Currently, SMT manufacturers install a 3D AOI inspection machine after the nitrogen furnace to enhance the quality of high-end products. They also install a 3D AOI inspection machine before the nitrogen furnace to accommodate the inspection of increasingly precise and small components, meeting the requirements of international major customers.
This paper aims to investigate the roles of different participants, the level of market competition, and their impact on the overall economy through the S-C-P model. Further research into the current development and trends of the SMT 3D AOI industry will facilitate the prediction of future directions and strategies, assisting manufacturers in the SMT 3D AOI industry to make informed decisions and plans.
Research results indicate that Taiwan′s SMT 3D AOI industry has a low degree of oligopolistic competition. In the future, SMT 2D AOI inspection equipment will be completely replaced with new equipment, and expanding production lines and establishing new factories will become the main demand market. By expanding facilities, increasing production lines, strategic alliances, diversifying operations, and investing in research and innovation, manufacturers can increase their market share and achieve economies of scale, making them more competitive compared to other companies and following the trend of ＂the bigger, the better.＂
The SMT 3D AOI industry is an upgraded sector from 2D AOI. Besides improving inspection accuracy and speed, its main contribution is providing stability, reliability, and trustworthiness to the industry. It is believed that the use of 3D AOI technology will become more prevalent in the future. Its benefits to the industry include reducing labor costs, improving product quality and yield, optimizing processes, increasing product lifespan, reducing rework and returns, and contributing to sustainable operations by reducing carbon emissions.
This thesis analyzes the development of the 3D AOI industry using the S-C-P model. It focuses on the market structure, firm behavior, and industry performance of the Taiwanese SMT 3D AOI industry. It also examines the current status and discusses the evolving trends and future development of the SMT 3D AOI industry. Finally, it proposes strategies and recommendations for the industry participants in the SMT 3D AOI sector. | en_US |
