ESD damaged components more likely to blow up when dv/dt is high?

[ocset]

We suspect ESD damage to some of our components….possibly the damage being caused before the components got put on the PCB.
To ensure that PCB’s with ESD damaged components don’t get out to our customers…we want to instigate the ESD failure in our production test facility.

The products are offline LED drivers. They have no electrolytic capacitors, and basically the components suffer a higher dv/dt at switch-on if the switch-on happens at the instant of mains peak.
So we want to subject the products to an “on-at-mains-peak” tester, which turns them on repeatedly at mains peak.

But anyway, do you believe that an ESD damaged component is more likely to blow up when its rail voltage rises with higher dv/dt?

This must be for sure another treez trolling day, it's raining outside, it's raining here with treez-style questions 

When you talk about a commercial product that will be released on the market you are not allowed to even think to start any product related sentence with something like : "We SUSPECT ESD damage to some of our components...".
Usually you are are just suspecting something about something out there or you are searching to have a solid proof or what? Are you using proper engineering testing methods out there or just using prays, voodoo or any whatever other esoteric method of testing?

Perform an IEC 61000-4-5 surge test.
