SMT component temperature spec | 4 March, 2019

What temperature spec are people using in the industry to make sure an electronic component is SMT reflow compatible ?

Ex. I have some parts that I want to possibly process as Pin in Paste but am not sure what temperature ratings the plastic will meet ?

All Lead-free compatible. Appreciate the help.

The lowest peak temp. I've had the pleasure of working with is 240°C +/- 5°C.

I can't imagine a manufacturer going much below that and still saying it's lead-free compatible.

It would be interesting to know just how much TAL plays into the affects on a pin-in-paste reflow too. IOW, can 30 seconds above liquidus do more damage than a momentary peak of 240?
