Solder paste has stencil life time - if you go over it means you should change it. If you print boards in front and keep them for too long before reflow, the flux is still evaporating, so you are not mitigating the risk. Paste also likes room tempera

Hmm... how about the people inside this room; working in this dry environment? This is something never discussed highly, but I believe it is most certainly important for the human health. This is another interesting thing about RoHS; the side effects

Where in the world are you? Is it naturally that dry and you'e trying to keep it up, or do you dry it to that state? 'round here 40-45 is the norm so we don't put much thought into controlling it.

I'm wondering if everyone can give me opinions on what the industry standard is in a contract manufacturing environment for bare board PCB storage in terms of mitigating delamination and MSD related defects. Our facility is currently using vacuum s

We need to dry and clean the air in our dedicated poting and conformal coating room. Can anybody help on how to go about it. The airconditions only recycle and dry until room temperature is reached and therefore have great fluctuations and unstable p

We use dry boxes manufactured by DMS Clean Room Products in Lawrence, MA. The phone number on the tag is (508)683-2325, but I think their area code changed to either 978 or 781 recently. We flow dry nitrogen through the box in order to ensure that

Find out if you can separate the dehumidifier controls from the heating/cooling controls, without adding an air handler. Otherwise I think you'd need to add a dehumidifier that runs independantly. Don't forget that system capacity has to be rated fo

Purex makes a system for air filtration of aqueous washers. I believe the only fully self contained system available. It returns all cleaning solution back to the cleaner and exhausts clean dry air back to the room. You can contact Dick Wilson at Pur
