Die Per Wafer Solution

Follow our step by step solution on how to calculate Die Per Wafer?

FIRST Step Consider the formula

DPW = \frac{π \cdot {d w}^{2}}{4 \cdot S d}

Next Step Substitute values of Variables

∴

DPW = \frac{π \cdot {150mm}^{2}}{4 \cdot 22mm²}

Next Step Substitute values of Constants

∴

DPW = \frac{3.1416 \cdot {150mm}^{2}}{4 \cdot 22mm²}

Next Step Convert Units

∴

DPW = \frac{3.1416 \cdot {0.15m}^{2}}{4 \cdot 2.2E-5m²}

Next Step Prepare to Evaluate

∴

DPW = \frac{3.1416 \cdot {0.15}^{2}}{4 \cdot 2.2E-5}

Next Step Evaluate

∴

DPW = 803.248121656481

LAST Step Rounding Answer

∴

DPW = 803.2481
