AVX and a few other companies make these chip transient voltage suppressors (TVS) parts that are a real *PAIN* to use. According to AVX: "Due to the semiconducting nature of the doped Zinc Oxide (ZnO) ceramic material, SMT TransGuards are no

I have seen this before, our problem was palladium termination of this component. We could not change suppliers so we use a "reverse homeplate" stencil design to put the majority of paste directly underneath the solder terminations of the component

Hey Bud: Moved from that Bi-crap to something serious, eh? Several things: 1 Get in touch with Doug Romm (drom@msg.ti.com) at Texas Instruments. He talks palladium. 2 Review the archives on Palladium. 3 I think you're running light on temps. Eut
