[Product News] Optimizing MCB Assembly Yield: How Component Precision Reduces Total Manufacturing Cost This technical article breaks down why relying solely on low Bill of Materials (BOM) costs often leads to higher overall manufacturing expenses for Miniature Circuit Breaker (MCB) OEMs. By analyzing the physical and process-level root causes of automated assembly line jams, calibration bottlenecks under
IEC 60898-1, and temperature rise test failures, this guide demonstrates how sub-assembly component tolerances ±0.02 plate pitch, ≤0.4mΩ contact resistance) directly boost First Pass Yield (FPY) and eliminate expensive factory rework.
