|---|
| Core Role | Provides PCB/PCBA manufacturing, assembly, testing | Produces products based on client’s design | Designs and manufactures products, clients rebrand |
| Design Input | Client provides design, EMS ensures manufacturability | 100% client design | ODM provides design, limited client input |
| Customer Control | Full control of R&D and branding | Full design & brand ownership | Brand control, limited design control |
