EMS, or Electronic Manufacturing Services, is the collective name for all processes and services used to create electronic assemblies. This includes operations like:
Surface Mount Technology (SMT) assembly
Printed Circuit Board (PCB) assembly
Electronic enclosure design and build
System integration of multiple sub-assemblies
Testing and verification of the product
EMS allows manufacturers to outsource the production of their products so they can focus on more essential business operations such as research and development, marketing, and sales.
