Sunon: we used Sunons some years ago in our products, most of them had premature noise after few months usage. We chaged to Delta since 3 years.
Sorry, if I was not precise enough: when the board are connected, and has a proper connection to gound and housing, you cannot damage the ICs with ESD.
BUT during production (till the board is alone with it's ICs) you can damage several ICs on the board, just by touching it, like imagine the people assembling the board intot the housing, and charged. As there is nothing which is connected -may dissipate the electrons- they stay and damage the IC. That1s why double ESD protection is needed on all employees working on the line: ESD shoes + ESD bracelet.
