Copper wiring density : L1 = 90% / L2 = 95%
1) The data for the case with the Exposed Die-Pad substrate mounted shows the values when 95% or more of the
2) For the set design, employ the derating design with sufficient margin.
3) After the set design, be sure to verify the design with the actual product.
(1)Maximum value 80% or less for the voltage rating
(2)Maximum value 80% or less for the current rating
(3)Maximum value 80% or less for the temperature rating
Exposed Die-Pad is wet.
Stresses to be derated include the voltage, current, junction temperature, power loss, and mechanical stresses such as
vibration, impact, and tension.
Accordingly, the design must ensure these stresses to be as low or small as possible.
The guideline for ordinary derating is shown below :
Confirm the solder joint state and verify also the reliability of solder joint for the Exposed Die-Pad, etc.
Any void or deterioration, if observed in the solder joint of these parts, causes deteriorated thermal conduction,
possibly resulting in thermal destruction of IC.
