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'

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

3a ANSI/J-STD-001: * Temperature and Humidity: 18-30°C, 30-70%RH ** If out of range, shall verify electrostatic discharge control program according to ANSI/ESD S20-20 is adequate. ** For process control, more restrictive temperature and humidity lim

Hi Mark, If you are a user of stencils, you already know that there are literally hundreds of stencil manufacturers out there. If you found one that will allow such hot temperatures, I would be interested in learning who it is. However, I have only

Per ESD Handbook TR 20.20 paragraph 5.3.15 Humidity "Humidity is beneficial in all ESD Control Program Plans. Contact and separation of dry materials generates greater electrostatic charges than moist materials because moisture provides conductivity

You�re correct about J-001. It�s interesting though, I find no references to controlling temperature and humidity as an element of an electrostatic discharge control program in the following: * ANSI/ESD S20-20 * "ESD Program Management" by Ted Dan

All of the discussion of "environmental controls" are a matter of degree, dependent on the requirements of the product that you manufacture. For example: shops assembling under-the-hood products have different requirements than shops making garage d

| I know that static concerns are very important in your work. Are static concerns eliminated by the antic-static devices you wear or which are in your environment, or do the hand tools you use, such as picks, tweezers and brushes, need to be anti-st

No we do not use such a storage unit. We say our preferred environment is within: * 30%RH / 84�F * 30%RH / 72�F * 70%RH / 78�F * 70%RH / 68�F J-001C says [words to the effect of]: * At 30%RH and below you�d better make sure your ESD control program

Ashok: Haven't unloaded that ESD Coordinator job yet have you? Smocks: Don't work, they're hot, and no one likes them, but they put up with them (sort of). Now if they knew they didn't work, all the customer PR in the world wouldn't help. The bi
