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?
