South Africa and IEC version
Greetings to everyone: I'm in need of information about SABS enforcement for ITE computer peripherals (USB, serial, PS/2), specifically for some older ITE products already certified and imported in South Africa. SABS has recently upgraded their national standard to follow IEC 60950-1:2001. At the present moment, my client's distributors are being asked to provide evidence of 3rd Edition approvals or certificates. The products in question (tested and certified in year 2000 and later), and are covered by a CB certificate listing IEC 60950:1991+A1+A2+A3+A4 2nd Edition. Without considering the EMC requirement, will 60950 2nd Edition up to A4 be enough for a distributor to sell product already on the shelf in South Africa? Is there some announcement or bulletin which states as much or which spells out some different requirement? Thanks in advance for your advice, Angus McGill Cascade Engineering Services, Inc.

BSMI approved printers
Hi group: I'm looking for HP printers to be part of our EMC host systems (ITE emissions and immunity). One requirement is that the equipment have BSMI approval, evidenced by a BSMI logo or number on the product label. Sales people I have contacted at HP do not seem to have this information, there seems to be no list of agency approvals on the website, and no time to drive around to the shops and look at labels. Can anyone point me to the right person at HP, or another source for this information? Regards, Angus McGill Cascade Engineering Services, Inc.

Azerbaijan bluetooth
Hi group. A quick question: Does anyone know what kind of certification or DOC is required for bluetooth computer peripheral products in Azerbaijan? Though Azerbaijan is a former CCCP member, I wonder if a GOST certificate is required for import or operation there. The product in question bears the CE mark and is listed on a DoC for Directive 1999/5/EC. Regards, Angus McGill Cascade Engineering Services, Inc.

RE: Power Adapter LPS
Hi everybody. Thanks very much for your helpful comments. The issue is put to bed now on my end, and I will revert to listening in for a while. We have decided to have the adapter looked at under both regimes for the additional edge, whether strictly needed or not. Angus McGill Cascade Engineering Services, Inc. From: Peter L.

From: richhug...@aol.com Sent: Monday, May 12, 2003 5:47 PM Peter, I presume that you replying here for product use in North America only? Yes. UL1310 being a US standard with close ties to NFPA70, Article 725 and a title of Class 2 Power Units (used to be titled Direct Plug-In Transformer Units). Also, all standards references were to UL standards, leaving the distinct impression of a North American only query. Admittedly, this is sometimes not the case. The original question was about meeting LPS requirements in UL 60950 and Angus McGill asked if having such a supply would help in obtaining UL approval for the IT equipment (i.e. ITE). I've already deleted the original posting, but I believe the question was related to whether or not additional testing of a Listed Class 2 Power Unit to LPS requirements would aid in obtaining certification. If this was the question, the answer is no. If the question was intended to go beyond this, then, certainly, the issues you mention and many others, still need review. Regards, Peter L. Tarver, PE Product Safety Manager Sanmina-SCI Homologation Services San Jose, CA peter.tar...@sanmina-sci.com From: Peter L. Tarver Sent: Monday, May 12, 2003 2:40 PM Angus Doug - Even though 1310 power supplies may only comply with Basic Insulation (per UL60950), they have the bejeebers tested out of them. UL1310 emphasizes testing over construction, whereas UL60950 emphasizes the contrary. Since a UL1310 power supply must meet the requirements for NEC Class 2 power sources, there is no need for any additional testing to demonstrate compliance with LPS requirements in UL60950. The LPS requirements are derived from (though somewhat less stringent than) NEC Class 2 requirements. Regards, Peter L.

RE: best screw/washer choices for attaching PCB to Chassis?
Has anyone tried square-cone sems screws for holding down PCBs? I am tempted to recommend them, as I've seen them used in this type of application, They have properties of flat and locking washers in a single, captive washer (fewer parts to manage). They come in 4-40 phillips pan head, with zinc or other platings.

The product I'm referring to used screws to fasten a two layer FR4 fiberglass/epoxy PWB to copper bars. I think it had a 5V output at about 50A. The memories are really foggy since this was about twenty years ago, but as I recall it used a couple screws with flat and split lock washers. Although properly torqued in initial manufacture, they started coming back from the field after a year or two with failures where the hardware had loosened and the resulting loose connection would progress to heating and arcing with destruction of the board in the joint area. The smoke and charring brought it to the attention of product safety, but failures never generated further risk due to enclosure protections. We didn't do a lot of research as to how the failure progressed, just reworked the product so that etch was securely soldered to the connections and did not depend on the screws. Board compression may have been due to heat cycling or simply cold flow. However, the connection eventually loosened and that was what we had to fix. I have often seen grounding done with board mounting screws and have recommended against it. Grounding doesn't experience any heat cycling, nor does it usually experience sustained currents which burn the connection, but if it loosens, it is not usually obvious in the field. You probably can't calculate a prediction about compression. You would need to do lab experiments plotting compression against time, pressure and temperature. It's easier to just find an alternative construction.

That's interesting. I can understand that the glass in the PCB is a fluid and will flow over time. But is there something more quantifiable than gradually squashes? Would this mean by next Thursday, next year, or 1000 years from now? By how much would it deform over time? If I wanted to calculate this effect, how would I do that? (I'm an electrical engineer - fluid dynamics is a very distant memory at this point) In the particular case I'm looking at right now, this connection is not serving as a DC power path so I'm not so concerned about arcing here. However, it would be interesting to understand this better for future designs. In fact I might be more concerned about the screw actually coming loose as a result of this compression, however I've never heard of such a thing. I guess that returns me to my locking washer question. thanks, kim From: Robert Johnson [mailto:john...@itesafety.com] Sent: Monday, February 10, 2003 8:09 PM To: Kim Flint; emc-p...@majordomo.ieee.org Subject: RE: best screw/washer choices for attaching PCB to Chassis? You should not include the PWB as part of the sandwich in an electrical connection. It gradually squashes and leaves a loose connection. The answer is generally to use a soldered jumper and lug to make connections from board to chassis. The same applies to other board connections such as board to busbar or similar connections. We have experienced arcing and board destruction due to such designs on DC power output connections.

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.
