EMS stands for Electronics Manufacturing Services, also known as Electronics Contract Manufacturing (ECM), which is a rapidly growing industry. It refers to companies that offer contract manufacturing services for electronic components and equipment. As manufacturers for electronic product brand owners, these companies provide a comprehensive range of services, including manufacturing, procurement, part design, and logistics. EMS offers a wide range of services in the electronic components field, making them the preferred service provider for companies in this field.

Compared to traditional OEM or ODM services that only provide product design and contract production, electronic manufacturing service companies offer knowledge and management services, such as material management, logistics transportation, and even product maintenance services.
