what is resonance filter? what is bond wick?

Answer 1

Resonance filter is a filter circuit designated to oscillate, or resonate, at a particular frequency, and thus block (or pass) that frequency.
Bond wick is a trade name for de-soldering braid, a repair tool service people use to remove solder from a component. It works by soaking up the melted solder much like a sponge soaks up water.
