Tim,

Thanks for your article. Based on the comments below, I'd say think about submitting another "war" story.

Many of us have had ESD issues. I once blew out a PC motherboard while installing a hard drive. After that, I started using ESD writst straps. But, I learned that they disintragrate over time and I had to get new ones this year.

Great article! Today's components and assemblies are more efficient and smaller than ever before. They're also much more delicate and sensitive to static electricity. Even a tiny charge of electricity -- one that you can't see, hear or feel -- is as damaging as a bolt of lightning to components and assemblies.

Great column -- it nicely complements the one I wrote recently: Zapping Things with ESD -- Just One More Service I Offer

Reference circuits are good to start design. But, with reference circuits, many designers avoid reading datasheets in detail and forget abou innovation and safe design. Many similar problems can be avoided by detail study.

It's been a while since I have seen a well detailed article like this. Thanks for taking us through the details with an interesting narrative.

Thanks Timothy for a well-written and informative war story.  Not all customers wear wrist straps, these 'little' design details can make or break the success of a product.

"The misunderstanding that we needed to dispel, however, was that the ±15 kV rating on the device datasheet of the TVS clamp has little to do with the system-level protection threshold he would achieve on his PCB."

 

Unless it was an intern, in which case it may be excusable, it sounds to me like he was in the wrong job if he did not understand this basic fact.
