Introduction
The electronic manufacturing services (EMS) industry plays a crucial role in the production of electronic components and end products for a variety of industries. EMS companies manufacture electronic components and assemblies for original equipment manufacturers (OEMs) based on their specifications.
The EMS industry has grown rapidly over the past few decades, driven by the rising demand for electronic products and the trend of OEMs outsourcing manufacturing to external suppliers. Some key benefits of outsourcing to EMS providers include access to advanced manufacturing capabilities, flexibility, and cost savings.
This article provides an overview of the top 30 EMS companies in the world, based on revenue. The rankings offer insight into the major players in the competitive EMS market landscape. Understanding who the leaders are can help OEMs select the right manufacturing partner for their needs.
