See Figure 5. This label is required on the moisture barrier bag and/or the lowest
2、level shipping container. The label must specify the peak package body temperature at which the device was classified. If the required information is not provided on the caution label then it must be on the adjacent bar code label. Level 6, as defined by J-STD-020, does not require that devices be s
3、hipped in a moisture-barrier bag with desiccant, etc. (dry-pack), since these devices require baking by the end user before use. However, moisture-barrier bags have become a “symbol” for moisture-sensitive devices and therefore are recommended to be used with level 6 device shipments. It is also rec
