Re: [PSES] ESD Table Top Testing Bench with IEC 61000-4-2
Hello Kevin - Interesting question. Keep the old wooden benches - after all your company has shipped several products using those benches. The issue for me is that you should not claim compliance to 61000-4-2 if the test fixtures do not comply with the requirements of said specification.

It is very likely that the capacitance to the ground plane would be much higher with the steel-legged table. Are you really serious about feng shui? With best wishes DESIGN IT IN!

Re: ESD TABLE
Hi Bill, At 3Com the insulator we use is 2 thicknesses of a polycarbonate material. The material is supplied to us by one of our label manufacturers. This is acceptable to UKAS in the UK as our facilities have just received accreditation. I will forward on the details of the supplier when I get back in to the office next week.
