Need of ionizers

Hello,

Considering the need for static control with ungrounded conductors above 35V and out-of-spec insulators, is there a risk of static charge buildup on a PCB when it’s heated in a rework station?

Also question: do you usually have ionizers in your rework stations? what is your technical rationale? (besides ungrounded conductors above 35V and out-of-spec insulators)

Thank you!
