The period between drying and sealing must not ex

44、ceed the MET less the time allowed for distributors to open the bags and repack parts. If the suppliers actual MET is more than the default 24 hours, then the actual MET must be used. If the distributor practice is to repack the MBBs with active desiccant, then this time does not need to be subtract

45、ed from the MET.3.2.2 Drying Requirements for Carrier Materials Carrier materials, such as trays, tubes, reels, etc., that are placed in the MBB can affect the moisture level within the MBB. Therefore, the effect of these materials must be compensated for by baking or, if required, adding additional

46、 desiccant in the MBB to ensure the calculated shelf life of the SMD packages.3.2.3 Drying Requirements Suppliers may use the drying effect of normal in-line processes such as post mold cure, marking cure, and burn-in to reduce the bake time. An equivalency evaluation is recommended to ensure that h

47、igh temperature processing maintains moisture weight gain to an acceptable level. The total weight gain for the SMD package at the time it is sealed in the MBB must not exceed the moisture gain of that package starting dry and then being exposed to 30 C/60% RH for MET hours (less the time for distri

48、butors).3.2.4 Excess Time Between Bake and Bag If the allowable time between bake and bag is exceeded, the SMD packages must be dried again per Clause 4.3.3 Dry Pack3.3.1 Description Dry pack consists of desiccant material and a Humidity Indicator Card (HIC) sealed with the SMD packages inside a Moi

The bags shall be heat sealable. The Water Vapor Transmission Rate (WVTR) shall be 0.0310 g/m20.002 g/100 in2 in 24 hours at 40 C after flex testing per condition EASTM F 392. The WVTR is measured using ASTM F 1249.3.3.2.2 Desiccant The desiccant material shall meet MIL-D-3464
