S&C Mexicana Fuse Products Team
FUSE PRODUCTS: TACKLING ELECTRICAL RESISTANCE AND PAINT DEFECTS In our Fuse Products in Mexico, two persistent issues were driving up DPU: high electrical resistance in SMU-20 fuses and frequent paint defects on fiberglass tubes. SMU-20 fuses are designed to interrupt high fault currents, and resistance issues can compromise performance. “The team conducted Gage R&R analyses and implemented 100% resistance checks at key assembly stages, along with operator certification for soldering,” said Oscar Navar, manager, quality assurance. “For the painting defects — mostly caused by poor adhesion and equipment issues — the team standardized painting methods, switched solvents, improved cleaning procedures, and certified operators across shifts.” These efforts led to a more than 80% reduction in resistance-related defects and a 90% drop in the top painting issues, with DPU improving from .065 to .022 in just a few months.
