- Acts as project leader leads all aspects of a variety of projects, work with factories and manage on technical and quality. - Collaboration with upstream and downstream on design, process, quality, specifications and issues. - Plans, develops and implements technical procedures for Flexible Printed Circuit Assembly (FPCA) manufacturing process&quality requirements. - Provides early manufacturing involvement to ensure new products is manufacturable. Perform design, manufacturing process, quality review, identify design and manufacturing risks, provide design and process solutions during New Product Introduction (NPI) to mass production(MP), and handle the implementations and qualification. - Establish guidelines, Standard Operating Procedure & Best Known Method for manufacturing process & quality control. - Support projects in different regions, manage NPI projects and builds, improve quality and efficiency, to ensure seamless transition to MP.
Collaborate tightly with the Cupertino Engineering team to validate product designs for manufacturability, recommending design changes to drive high quality (yield and reliability) and cost-effectiveness. Develop innovative and creative manufacturing processes and stations. Provide expert guidance and resources to contract manufacturer (CM) engineers. Support product builds through all developmental stages (Proto, EVT, DVT, PVT) and seamlessly into mass production ramps. Plan, develop, and implement rigorous procedures for PCBA, SIP, module manufacturing processes and quality control at CM sites. Partner with cross-functional teams to define requirements and establish suitable performance metrics for new processes. Lead cross-functional efforts to ensure the successful transition of projects from engineering to mass production, or during site-to-site transfers. Act as the primary project leader on a variety of complex manufacturing and engineering projects.
