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

Joe: Hey, just hose everyone down with water when your humidity starts to decrease to below 40%. ;-) Actually, that�s how some humidity controllers work, when added to your heating system. Well basically that�s how they work. I�m not tryin� to

Thanks for the info. Our system is capable of holding the set limits, but since breakdowns do happen I am considering what to do. So while everything is running, we have a climatic controlled area. The min. relative humidity of 40% comes from the JE

Joe: That's what we do ... when the trend line is downward and below 40�C we start thinking. Apparantly, that's exactly what you do, except it's a matter of degree. Good luck. Dave F

We use a "McDry" cabinet for humidity control of opened, moisture sensitive parts. Relatively cheap and works good. This cabinet is installed right on the SMT line. Check out: http://www.seikausa.com/products/mcdry/

Mariss, I would run a power analyser on your oven to see the real power consumption during warm-up and during production. Then you would be better able to decide how much money to invest in a humidity controled cabinet big enough to contain your dail

Emmanuel: Popcorn effect is mostly caused by entrapped moisture in the components package material. Plastic ICs are known for absorbing and storing moisture when exposed to normal factory conditions. They should be stored in an moisture reduced envir

Hi, "Baker with controlled humidity 5%" is actually dry cabinet. Using of dry cabinets i.e. ambient temperature baking is preferred. Vacuum will always be better. If you are going to use vacuum chamber, that will be the best method in my opinion.

In an oven over 100 C any moisture will escape through vents. There will not be huge volumes of moisture in the oven when you are baking components so it should easily escape through vents / holes in the system leaving you with a humidity of near zer

Okay... to follow-up on my scenario. Would it be cheaper to get a resealer with dessicants and humidity indicators or a baking oven, or both. Is there a moisture controlled storage cabinet (ideally 3'x6'x1' or in that vicinity)? Would be interested
