MSD Control in low humidity environment | 4 August, 2015

Hi folks,

I was wondering what the combined wisdom was on the humidity effect on the MSD control required by the Jedec std. The std works on a relative humidity of 65%, if my RH is only say 30% because of factory environments how do I easily factor this in to the floor life allowed for components?

John,

I assume you mean 60%, not 65%. J-STD-033 has a derating table for floor life which accounts for conditions other than 30C/60% RH. Table 7-1 is what you're looking for I believe.
