7.  RECOMMENDEDTEMPERATUREREFLOWPROFILE
Priortoanyreflow,itisimportanttoensurethemoduleswerepackagedtopreventmoistureabsorption.Newpackages
containdesiccate(toabsorbmoisture)andahumidityindicatorcardtodisplaythelevelmaintainedduringstorageand
shipment. If directedto bake units on the card, please check the Picturebelow and follow instructionsspecified by
IPC/JEDECJ‐STD‐033.
Note:Theshippingtraycannotbeheatedabove65°C.Ifbakingisrequiredatthehighertemperaturesdisplayedinthe
Picturebelow,themodulesmustberemovedfromtheshippingtray.
Anymodulesnotmanufacturedbeforeexceedingtheirfloorlifeshouldbere‐packagedwithfreshdesiccateandanew
