Wrist straps are used to bring the operator to ground potential which is the same potential as the dissipative worksurface and the electronic device which is on the bench. Everything must be at the same elctrical potential. Wireless straps will not d

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

There are two similar products, Eureka and McDry dry box units and other nitrogen required units in the market. Both Eureka and McDry are not required Nitrogen, I'm seeing a cost saving there in the long run. I have several Eureka dry box in the faci

Handling requirements of all classifications of moisture sensitive devices is found in J-STD-033. It really isn't an issue for most parts unless they're going to reach reflow temperature again, which is unlikely unless you're removing a nearby compo

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
