Process Optimization Using Value Stream Mapping in PCB Manufacturing

PCB Manufacturing process is a complex process and has several processes and sub-processes. Adopting a lean manufacturing system will help to increase the efficiency of the system. This study aims to optimize the process for PCB manufacturing using value stream mapping. Observation method has been used to collect the cycle time of different processes from a PCB manufacturing plant in India. Pareto charts, why-why analysis and Ishikawa diagrams have been used to do the analysis and optimize the process and create a value stream mapping for the entire process. Standard Operating Procedures have been framed and solutions to increase the efficiency has been proposed.
