| Abstract | Viet Nam Assembly and Test (VNAT) factory started to produce Chipset product since 2010. Four years later Global Intel decided continue to ramp up VNAT with CPU and SOC product at 2014. From 2016 to now VNAT are continuously producing trip products with full investment from Intel Global. VNAT is considered as ramp up site with multiple machines and mass production, this factory delivers 75% finish-good across a virtual factory over the world. With the significant ramp up site, hiring and training worker to operate mass production/high mixture take time and is a critical mission. However, hiring a correct number of workers into a sub link or tool is also a challenge. Based on 2018 finance indicator; outsourcing Assembly and Test competitor (OSAT) reports the head count per tool (HC/T) number should be X.X. However the number of VNAT site is X.XX, higher than 0.35 versus the goal. Therefore, site management are going to work on this object to drive down a HC/T back to expect X.X number. The concept of X.X or XX.X should be explained! Even though VNAT has a machine man ratio (MMR) model for CPU/Chipset/SOC, but we still lack of the model for trip product. On another hand, the trip product flow and technology are also different versus with CPU/Chipset/SOC product and the workers need to support multiple products when needed, that is why in this project we will study, apply and define the correct model for trip product to avoid overloading or low loading head count which is an important mission of site. In this project, I will show the specific module call Wire Bond(WB) operation for example, this is the true case I did involve by applying Lean (Kaizen Event) to make the MMR from 1 to 6 ( one worker take care six tools) at the beginning to improve to 1 to 15 now. The main propose of this study is a part of the mission to drive a DL/Tool down to X.X and define a precise model to help Intel Viet Nam factory worker work more efficiency. |
