3 Ways to Ensure Your EMS Provider's Supply Chain is Excellent
As an original equipment manufacturer, once you’ve outsourced your manufacturing to an electronics manufacturing services provider, you will have very little hands-on involvement with your materials supply chain. And that’s a good thing because it means you have more time to focus on your core competencies (i.e., designing and selling your products).
Product Compliance Requires Supply Chain Transparency
Changes to the RoHS, REACH, and conflict minerals regulations make the need for supply chain transparency more crucial than ever. In line with this, full material declaration (FMD) is quickly becoming the "gold standard" data requirement for an OEM to accurately assess the risk of restricted materials in a product.
