Hi,

I am enquiring into the acceptable conditions [ie. temp. and Relative
Humidity] for long term storage [ie. 8 to 10 months] of level 6 moisture
sensitive smt components.

I am aware that moisture sensitive components of levels 2 through 5 require
an RH of less than or equal to 20% RH for long term storage, but does this
apply to levels 5a and 6, or is a lower RH necessary? I ask as I have no
level 5a information to check on, and level 6 information is individual to
the component.

Thankyou for taking the time to read this,

Regards,

Richard Tilbrook,
