Description: PEMS are Plastic Encapsulated Microcircuits. These microcircuits are susceptible to moisture exposure and therefore must be sealed in an airtight plastic bag with desiccant when not in use. In certain circumstances PEMS must be subjected to a bake process are required to be baked before installation onto the PCBA. There are different levels of sensitivity and these are determined by the vendor. Level 1 is common and does not require bake out. Level 2 through Level 5A have different levels of exposure that they can be out of these sealed bag or a dry box for.

PEMS Cycle Time is the time required to unpackage, bake (when required), and reseal PEMS components for the specific PCBA.
