A Appendix - Wirebond Derating Curve

Derating Curve Based on Passing Wirepull Results After 420hr at 175C Figure A-1 Derating Curve Based on Passing Wirepull Results After 420hr at 175C

Acceleration factor (Af) is based on the equation:

Equation 1. A f   = e E a k 1 T u s e   -   1 T t e s t

Where:

Ea = Activation Energy (eV), Assuming 1.1eV for Kirkendall voiding.

k = Boltzmann’s constant

Tuse = Use Temperature in Kelvin (°C + 273.15)

Ttest = Test Temperature in Kelvin (°C + 273.15)
