What are Electronic Manufacturing Services?

Electronic Manufacturing Services is the term used to describe companies, like Green Circuits (a PCB assembly manufacturer), that offer design, manufacturing, assembly, testing, distribution, analysis and repair services for electronic components, such as PCBs (printed circuit boards), wires and cables on behalf of a product’s manufacturer, or OEM (original equipment manufacturer).

Types of EMS Providers?

Often there are two types of EMS providers, (HMLV) High Mix Low Volume and HVLM (HVLM). A provider is classified as HMLV or HVLM based on their output volume, unit built, and the complexity or variation of assemblies completed by the provider. Green Circuits specializes in HMLV and HVLM quick-turn PCB assembly.
