EMS companies work closely with OEMs to understand their specific requirements and provide customized solutions to meet their needs. By outsourcing the production of electronic components and assemblies to EMS providers, OEMs can reduce costs, improve time-to-market, and focus on their core competencies, such as research and development, marketing, and sales.
The History of Electronic Manufacturing Services
The EMS industry emerged in the 1980s as a result of the increasing complexity of electronic products and the growing demand for outsourced manufacturing services. Initially, EMS companies focused primarily on printed circuit board (PCB) assembly and simple box-build services. However, as technology advanced and the needs of OEMs evolved, EMS providers began to offer a wider range of services, including design, engineering, and supply chain management.
In the 1990s, the EMS industry experienced significant growth, driven by the rapid expansion of the personal computer (PC) market and the increasing globalization of the electronics industry. Many EMS companies established operations in low-cost regions, such as Asia and Latin America, to take advantage of lower labor costs and proximity to key suppliers and customers.
Today, the EMS industry is a critical part of the global electronics supply chain, with companies offering a comprehensive range of services to support the entire product lifecycle. The industry continues to evolve, with EMS providers investing in advanced technologies, such as automation, robotics, and Industry 4.0 solutions, to improve efficiency, quality, and responsiveness.
