best screw/washer choices for attaching PCB to Chassis?
Hi- We have a fairly straightforward requirement of mounting a PCB into a steel chassis. The chassis has PEM type standoffs and the PCB is held to them with machine screws. These connections provide an electrical ground path between the PCB and the chassis. In other words, we have what seems to be the fairly ordinary and common set of requirements. We need to have mechanical reliability (so the PCB is held in place), nothing should break during assembly, the screws should not be able to work themselves out, and electrical conductivity should be low for a low impedance ground path. Seems simple, yet all of us here have a different opinion about how to do this properly, we've all done it a variety of ways in our past, and none of us seems to have the right expertise to really claim to know the definitive answer. I'm hoping to get some expert opinions from this group, or at least some idea of what others do assuming there is some reasonable justification for it. Can you help? Or perhaps point me towards some good discussion on the subject? (I did search the 2+ years of mail I have from this group, since the archives don't seem to be online...) The questions are: Screw/Washer choice: - should a washer be used or not? - if a washer is used, should it be a locking washer? - Is it possible for a locking washer to cause unwanted damage to the PCB? - Is an adhesive like Loctite a reasonable alternative to lock washers in this case? - should the screw be zinc plated? or some other plating? PCB layout: - Should we use a plated through-hole with ground planes connected inside the hole? - or a non-plated hole with vias in the surface layer pad connecting to the ground plane? - What electrical or reliability concerns relate to this choice? - how large should the surface pad be assuming a 4-40 screw? anything else we should be considering? Thanks for any input you have! kim This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.

RE: Electrical Medical Product Production Testing
I would find it hard to think of ANY agencies that WOULD NOT require 100% testing. I was at a product liability seminar at British Standards Institute many years ago and someone asked about sampling levels for Earth Bond and Earth Leakage on consumer goods. The BSI panel took some time to understand that the questioner was serious. A lot of us took mental (and written) note of the company name - to ensure that we would not purchase anything from them.

Re: Electrical Medical Product Production Testing
Bill, There is no requirement by any agency to conduct a Production-Line Leakage Test. I think, it is up to the manufacturer to decide whether this test or any other test, including Production-Line Dielectric and Earth Continuity is needed. If manufacturer has a good quality system including receiving, in-process and final production, then why would someone need to spend money and time on production-line testing? I know that most UL standards require Production-Line Dielectric Strength and Earth Continuity Tests. On the other side of the ocean, most European standards do not require these type of tests and it is up to the manufacturer to show the test house that such testing is not required.

In the case of radiated immunity testing, the applied fields may penetrate the EUT, then travel through the I/O lines, and upset support equipment. This will result in excessive test time at the best, or improper indications of test failure at the worst. In the case of emission testing, support equipment will often inject noise onto the I/O lines, which is then conducted into the EUT. There, it may couple onto the EUT powerlines or be directly radiated. This will result in improper indications of emissions which do not truly originate from the EUT. All test chamber penetrations should be filtered as heavily as possible, consistent with not impairing the integrity of the data signals.
