Is TS-2414 insulating varnish material suitable for conformal coating of PCBAs? How can its performance be tested? What properties should be looked for on its data specs to conduct initial assessment if it is a suitable coating material?

A recording accelerometer is about the only thing I can think of. Unless you can find an insulative container (like for a profiler) you'd just have to run it through a cold oven.

There are no many moving parts in oven. Usially fan can give some vibration. Every heating zone have fan, so you can turn off them one by one and check vibration.

In my experience the largest contributor to vibration or other abnormal product movement in a reflow oven is deferred maintenance of a chain mesh belt conveyor.

We have a Rehm oven that can vibrate hard enough to shift parts on the board. The vibration is due to flux build up on the exhaust blower. If we don't clean it regularly we start to see parts shifting in the oven.

Can you possibly elaborate on your problem and why you think you have an unidentifiable vibration?
