[time-nuts] What do people use for measuring temperature?

[Bob kb8tq]

Hi

The gotcha with *any* SMT part is that stress / strain from the soldering process gets into the 
performance of the part for a *long* time. There is no mechanical “buffering” in most parts. Whatever 
the PCB does is what the guts of the part sees ….

Given the popularity here on the list of hand soldering SMT parts, that’s a very high stress way to
mount them …. yikes ….
