How to calculate first pass yield calculation

    • OpsDog KPI Reports First Pass Yield (FPY)

      First Pass Yield (FPY) Definition & Measurement Details The number of good units produced (output) by a manufacturing process without any rework divided by the total number of units that went into production (input) over the same period of time, as a percentage. First Pass Yield (FPY) is an indicator that gauges the production and

      that pass inspection (S) D. Process Rework Step E. Scrap Major Considerations Calculation of Process Yield using First Time Yield formula does not reflect the true process effectiveness. It often leads to an overvalued calculation of the true Yield, and has no practical meaning other than the ratio of successes over units tested.

      that exhibit distinct yield behavior, the intercept of the line through the stress axis represents a yield stress. Comparing the yield stresses for our two sealants we have 170 Pa for sample 1 and 510 Pa for sample 2. It is now a simple matter to set a maximum permissible yield stress for quality control purposes.
