3. IMPACTED AREAS
• TAPE AND REEL STATION – NEW SET-UP PARAMETERS
• PRODUCTION – LESS RE-WORKS
• MAINTENANCE – LESS MAINTENANCE CARDS
• QUALITY – LESS LOTS
• MATERIALS – CARRIER TAPE AND COVER TAPE USAGE
• MACHINERY – NO INVESTMENT ON NEW EQUIPMENT

6. OTHER POSSIBLE PROJECTS IDENTIFIED
• ELECTRICAL TEST IN OIL BATHS, WE HAVE CURRENTLY SOME ESCAPES AND THE PROCESS IS
TEDIOUS AND MONOTONOUS.
• COATING FOR THERMISTOR, WE HAVE A HIGH PPM ON COSMETIC DEFECTS AND THE CURRENT
COATING PROCESS HAS NO IMPROVEMENTS SINCE IMPLEMENTATION ON THE 90’S.
• INKING FOR FILM PRODUCTS, THE MIXTURE AND APPLICATION OF INK FOR RESISTIVE VALUE HAS A
LOT OF PARAMETERS TO CONTROL AND WE CURRENTLY HAVE HIGH SCRAP IN THIS AREA.
• MARKING FOR WIRE WOUND LVR PRODUCT, WE CURRENTLY HAVE HIGH PPMS DUE TO DEFECTIVE
OR MISSING STAMP ON THESE COMPONENTS
7. FINAL COMMENTS AND EXPERIENCES
• ANALYSIS OF VARIATION (MULTIVARI)
• INTERACTION PLOT (INTERACTION BETWEEN PARAMETERS)
• BOXPLOTS (COMPARISON BETWEEN RESULTS OF SET-UPS)
• THE WHOLE THING WITH THE DOE AND THE OPTIMIZATION PLOT
