Marking of plastic components
Hello Group, I keep hearing about a requirement to mark plastic components, supposedly in accordance with the WEEE Directive. However, I can't find anything in the WEEE Directive, or the ROHS Directive. I found a reference to ISO 11469 requiring marking of plastic components 25g, but can't find an equivalent European reference. I also found a reference to marking of plastic packaging for waste management, for parts 20g, but found no European reference for that requirement either. I scanned the emc-pstc archives but couldn't find any earlier related threads. Can anyone clear this up? Thanks in advance, Dave Wilson - Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.

Classification of network connections in Europe: TR 101 651 V1.1. 1 (1999-03)
Greetings All, After reading the above standard for the classification of telecom centers, Class 1, 2, 3 and 4, the standard references IEC 1000-2-5 to determine types 1, 2, 3 and 4. Does anyone in the group have the short definitions for the types from IEC 1000-2-5? The main purpose is to better understand the characteristics and definitions of telecom centers as they relate to Europe's central offices and customer premises. ETSI 300-386 does describe the telecom location, but not in great detail. Other documents that describe such telecom locations would be helpful. Thanks.

RE: PCBA Inspection Stamps
Doug, You could attach a process tag that goes with the board and have the inspectors and testers stamp that instead. I'm sure you could make your manufacturing processes accommodate the change and still maintain traceability. The product at the customer's site does not need the stamps on the PCB, you just need to maintain traceability during your manufacturing process. Just one low-tech option I'm sure. Dan -Original Message- From: POWELL, DOUG [mailto:doug.pow...@aei.com] Sent: Friday, December 06, 2002 6:03 PM To: EMC-PSTC (E-mail) Subject: PCBA Inspection Stamps Hello group, I have a request for information on stamping methods of PCBAs. I would normally post this question on one of the discussion forums for PCB design, but this question really does pertain to product safety. But first, please indulge me while I provide a little background information... My company uses a very large number of PCB assemblies with wide variety of technologies. Many of these boards have safety considerations and receive routine hipot testing during manufacture. As is normally the case, in-house and outsource assembly of the boards requires various kinds of inspection and test with stamps for validation. Traditionally these are rubber stamps or some form of an adhesive label with printing. Many of our boards have high voltage separation from SELV circuits and as it turns out the most convenient place to put a stamp is in a safety keepout zone. There have been a number of hipot failures that track right through this stamp. In our standard practices manual, we specify the use of only white epoxy based inks, but some of these are conductive as well. In addition, with the ever shrinking geometries of high density boards, placing a nonconductive stamp on a low voltage circuit interferes by insulating test points for bed of nails testing. Since inspection marks are usually placed by hand, the faults we see are fairly random. So, on the one hand conductive inks are bad and on the other hand nonconductive inks are bad. In an effort to solve this problem, we've considered providing a silk-screened area of the board that is safe to stamp, but real estate is now at a premium and solder-side silk costs on average about 10% more. Plus, it won't be long until computerized component ID and location eliminates the need for silk-screen entirely. My question is this: Has anyone discovered a technology or process of any sort, for marking of ultra-high density or high voltage PCBAs and is easy to implement in most board houses? I have to think that with all the technological advances the old rubber stamp or adhesive label could be replaced somehow. Who knows, maybe some form of UV identification? I am very interested to hear any success stories that you may have. Best regards to all, -doug Douglas E. Powell Compliance Engineer Advanced Energy Industries, Inc.

excessive crosstalk
Hi All, It's time for another short tech article Many of us in in the technical community know that crossing a path over a break in the ground/power planes on a board can have undesirable effects. One effect sometimes overlooked is excessive crosstalk that occurs between paths crossing the break. December's Technical Tidbit on my site at http://emcesd.com titled Crossing Ground Plane Breaks, A Source of Crosstalk presents measured data that shows the crosstalk, even that due to a short break in a ground plane, can be signficant. There is lots of stuff in the middle, but if you page down to the bottom of the page you will see the link to the article in the form of a picture of a circuit board with a ground slit. Right above that you will find a link to pictures from the latest IEC TC77b meeting. Doug -- --- ___ _ Doug Smith \ / ) P.O.
