If the actual shelf life has exceeded 12 months, but less than 2 years, from the bag seal date and the humidity indicator card HIC see Clause 5.
All testing occurs inside the chamber, while the cards are exposed to the test humidity. Special consideration should be given to non-hermetic cavity packages. Floor-life derating is discussed in Clause 7. If bake iedec interrupted for greater than 15 minutes the total time of the interruption should be added to the bake time. C If blank, see adjacent j-td-033b.1 code label 3.

The cards inside the chamber must be observable from outside the chamber. If the calculated shelf life is greater than 12 months, item 1 of the caution label should be changed accordingly. Requirement, paragraph number Test Method numberparagraph number The referenced paragraph number has proven to j-std-0333b.1 After bag is opened, devices that will be subjected to reflow solder or other high temperature process must be a Mounted within: This can be accomplished by dry pack according to Clause 3.
The supplier shall formally communicate to the distributor the maximum ipcc that the product may be left unsealed at the distributor before rebaking is required.
Non-semiconductor devices may exhibit additional process sensitivities beyond moisture sensitivity such as thermal sensitivity,? An equivalency evaluation is recommended to ensure that high temperature processing maintains moisture weight gain to an acceptable level. The following conditions apply regardless of the storage time i. Hue shall be tested using the test method in Appendix A.
