If the term of viability afteropening the antihumidity packaging elapses during your manufacturing span, be sure to apply a baking process to the productswith the heatproof tray before mounting the products.The recommended baking conditions are as follows:Package 1.8 mm thick or more: at 125 degrees C for 24 hoursPackage 1.7 mm thick or more: at 125 degrees C for 12 hoursPackage 1.0 mm thick or more: at 125 degrees C for 6 hours1.4 Analysis of nonconforming itemsWhen you remove our semiconductor products to analyze a nonconforming item, it is recommended to remove them afterbaking under the conditions mentioned in paragraph 4 above.
