A near real-time feedback loop between layout and assembly.
Two core tenets of Lean manufacturing philosophy are eliminating defect opportunities and minimizing process variation. Consequently, most companies embracing Lean principles do some form of design for manufacturability (DfM) analysis to identify manufacturability issues either during design or in the new product introduction phase. In some cases, this is an automated feature of design software. In other cases, this is done manually.
SigmaTron has adopted a hybrid process that uses software automation to speed basic analysis, followed by an engineering review. This E-DFM software tool reduces the time it takes to create a detailed report from several days to a few hours and works with SigmaTron’s existing Valor software platform.
Automating the process improves efficiency, since the engineering team reviews the automatically generated reports and suggests solutions for accuracy instead of individually performing a full analysis themselves. They then can make suggestions to further optimize the recommendations, as needed. The tool has been customized from industry-standard PCBA design rules and SigmaTron’s equipment/process-specific manufacturing guidelines, so it reflects equipment and process constraints.
