Hello, The company I work for are located in the North of Spain and the humidity levels in the factory range from 10 to 60 %RH. We have concerns about the low humidity effects on our ESD controls and want to invest in a system to keep the humidity a

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

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. Adam

OA pastes are more hydroscopic than NC pastes. Hydroscopic. The capacity of a material to absorb and retain moisture from the ambient air. Sometimes this is compounded if you remove paste from the frig and let it warm to room temperature, because

Hi All, Would just like to course through this concern on a product that we are contracted to assemble. It is mainly used for an automatic hand sanitizer dispensing product. By design there is a restrictive value of current that it needs to dissipat

68 to 72F, 25 to 30% humidity. IPC might have exact numbers.

J-STD-001 doesn't necessarily require additional controls under conditions of low humidity, only that you verify the effectiveness of what you have in place. ESD S20.20 [1999] only says that relative humidity above 30% is "desirable". ESD S20.20 [200
