Lets try this again, Every shelf system should be grounded individually. Every six feet per EOS/ESD requirements. Do not daisy chain anything. Secondly, Depending on the depth of paint,style of pain that your shelving system has. A static charge woul

Antistat sprays are a waste of time and money. These sprays just soaps disolved in water that absorb moisture from the air. Your minimum requirements: Conductive floor mats and wrist straps that are properly grounded. From there, consider using

Our SMT production and storage area is air-conditioned, constant temperature is maintained but the humidity is not controlled , the raw SMT material is stored in a "Drier" cabinet, but since we assemble hybrid SMT and thru-hole PCB assemblies, the SM

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

Hi, We have a climatic controlled assembly area, with a constant temp of 22 deg C and a relative humidity of 40 - 50 %. What I would like to ask is how should I approach a situation when the humidity starts to decrease to below 40%. The situation I'

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

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

Without being clear on whether you're talking about: * Standard air knives at the back-end of your in-line cleaner ... OR * Hand held or similar nozzle. Standard air knives: This causes no problem with ESD because the relative humidity is so high t
