OEM Audit of EMS Design-for-Manufacturing (DfM) Capability Checklist

At MexicoSMT, we understand the importance of choosing the right electronics design partner for your product program. That’s why we are offering a free OEM Audit of EMS Design-for-Manufacturing (DfM) Capability Checklist. We care about the quality provided by EMS providers and want to help decision-makers make more informed decisions when selecting their design service provider. This checklist covers critical areas such as component selection, manufacturing limitations, design-for-test roadmaps, and more. We hope this checklist will be helpful to you in evaluating EMS providers and selecting the right partner for your product program.
