What is High-Mix Low-Volume Manufacturing?
Within the expansive realm of EMS, the concept of High-Mix Low-Volume Manufacturing takes center stage.
A high-mix low-volume (HMLV) production environment is characterized by variability in assembled devices, including differences in production batch sizes, applied production processes, and final applications. EMS providers specializing in HMLV electronics manufacturing services possess the flexibility to adapt to frequent product changeovers, necessitating the reconfiguration of assembly lines within minutes. These providers excel in responding to changing requirements and managing increased customer demand.
Achieving success in high-mix low-volume electronics manufacturing requires precise controls and the expertise of skilled indirect resources. The inherent challenges in this environment elevate the risk of errors, making automation, a lean approach (including Single-Minute Exchange of Die or SMED), robust software control, and an organized, smart factory crucial elements in supporting HMLV projects.
What to Expect From Electronic Manufacturing Services Companies
