Evaluating Manufacturability and Operational Costs for New Conformal Coating Processes
Higher density components and smaller footprint layouts make the conformal coating process more challenging in terms of achieving acceptable first-pass process yields and cost-effective cycle times. This study of seven assembly process variables identified the three most critical variables and their impacts.
