Our die per wafer calculator tool helps you determine the number of dies that can fit on a wafer effortlessly.

## How to Use the Die Per Wafer Calculator

To use this calculator, input the following parameters:

**Wafer Diameter:**Enter the diameter of the wafer in millimeters.**Die Width:**Enter the width of a single die in millimeters.**Die Height:**Enter the height of a single die in millimeters.**Edge Exclusion:**Enter the edge exclusion in millimeters. This is the area around the wafer edge that cannot be used for die placement.

After inputting all the values, click the “Calculate” button to get the total number of dies that can fit on the wafer.

## How It Calculates the Results

The Die Per Wafer Calculator uses the following steps to calculate the number of dies:

- Calculate the effective wafer area by subtracting twice the edge exclusion from the wafer diameter to get a reduced diameter and then computing the area of this reduced diameter.
- Calculate the area of a single die using the provided width and height.
- Divide the effective wafer area by the die area to estimate the number of dies that can fit on the wafer.

The formula used is simplified and assumes an ideal arrangement without considering defects or actual positioning optimization which may be done in real-world scenarios.

## Limitations

This calculator assumes a perfect fit and does not account for possible issues such as:

- Irregular die shapes or layouts.
- Wafer defects or non-useable areas outside of edge exclusion.
- Real-world precision and manufacturing considerations.
