Abstract
Abstract Semiconductor assembly industry has been changing fast during recent years. As the midstream of IC assembly industry, IC substrate companies not only confront intense competition from Taiwan, South Korea and Japan, but also from international packaging and testing supply chain, hence clients have extremely strict requests for cost, quality and delivery. The heating up competition in market, fast-changing products and huge capital expenditure become a big challenge for IC substrate manufacturers, and how to make reasonable profits from limited source to sustain growth, it’s a big problem they have to face. In the past decade, the development of semiconductor processing and the change of both interior and exterior industry environment forced IC substrate manufacturers to establish factories in China. In the meantime, vicious price competition within the same industry and cost-down pressure from clients are nonstop, hence it become a critical issue to select best products mixed and utilize limited sources to make the company grow and bloom. My study incorporates the utilization rate of CCR (Capacity Constraint Resources) from Theory of Constraint with Throughput and Gross Profit Rate to find out the best Products Mixed, and use T/CU and image message to make correspondent marketing strategy to solve the problem of case company, which is the main purpose of my study.
