Introduction
In the realm of manufacturing and process improvement, First Time Yield (FTY) is a crucial metric. It represents the percentage of products or components that pass through a process successfully on the first attempt, without any rework or defects. The First Time Yield Calculator is a valuable tool that simplifies the computation of this metric, aiding industries in identifying areas for improvement and enhancing overall efficiency.
Formula:
The formula for calculating First Time Yield (FTY) is straightforward:
FTY (%) = (Number of Good Units Produced / Total Number of Units Started) x 100
Where:
- FTY (%) represents the First Time Yield as a percentage.
- Number of Good Units Produced is the total number of units that pass through the process without any rework or defects.
- Total Number of Units Started is the initial quantity of units that entered the process.
How to Use?
Utilizing the First Time Yield Calculator is a straightforward process:
- Input the Number of Good Units Produced: Begin by entering the total number of units that successfully pass through the process without any rework or defects.
- Input the Total Number of Units Started: Next, provide the initial quantity of units that entered the process.
- Calculate First Time Yield (FTY): The calculator will automatically compute the First Time Yield (FTY) as a percentage.
By applying this tool, manufacturing professionals can effortlessly gauge the efficiency and quality of their processes. The higher the FTY percentage, the more efficient and effective the process is in producing defect-free units on the first attempt.
Example:
Let’s consider an example in electronics manufacturing. You oversee the production of printed circuit boards (PCBs). Out of 500 PCBs that entered the process, 460 were successfully produced without any rework or defects. To calculate the First Time Yield:
FTY (%) = (Number of Good Units Produced / Total Number of Units Started) x 100 FTY (%) = (460 / 500) x 100 = 92%
In this case, the First Time Yield is 92%, indicating that 92% of the PCBs passed through the process without any rework or defects on their first attempt.
