Controlling warpage in BGA components in a re-flow process

The present invention utilizes wafer acceptance testing equipment to fast monitor the quality of an insulation layer. A plurality of swing time-dependent DC ramping voltages are applied to one of the electrode plates in a capacitor and each corresponding leakage current is measured to calculate each corresponding &#x3b2; value. Then, a ratio of each &#x3b2; value is calculated and a &#x3b2;-voltage curve is plotted to actually simulate the device failure.
