-----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Marsico, James - ES Sent: Tuesday, June 07, 2011 12:45 PM To: [log in to unmask] Subject: [TN] Connector Dust Caps Hello Technet: An issue has been raised at our facility regarding the material used for connector dust caps. As you probably are aware, connector dust caps can be either conductive (black?), dissipative (pink?), non-static generating or neither. It has always been our practice to use black conductive caps to protect connectors from FOD or ESD damage. One of our customers said that they would not allow us to ship them hardware with conductive connector caps, since they may shed some conductive fibers. Not being an ESD expert, I have a couple (few) questions. 1) When would you use a conductive cap over a dissipative one? Conductive would be used whenever you need to shield the pins below from potential ESD fields. 2) Would a dissipative cap provide the same ESD protection? No, dissipative is not a shield. 3) Wouldn't a dissipative cap also shed fibers that are conductive, but to a lesser degree? Technically dissipative and conductive are merely orders of magnitudes different with respect to conductivity. 4) What type of caps would you recommend for keeping out dust and offering static protection? I recommend black conductive. I'm sure that answers I receive will raise more questions.
