[time-nuts] pcb question

[SAIDJACK at aol.com]

Well said John!
 
0402, 0603, and even 0805 parts don't like to be pulled at all. Even  thermal 
contraction can make them fail, so care has to be taken.
 
FR4 material seems to work well, and not over-stress the parts when  soldered 
down and heated.
 
bye,
Said

I've  found it's helpful to add a mm or two of bare 24-gauge wire as an
expansion  joint whenever I mount a chip capacitor between the ground plane
and a  rigid support like a heavy conductor or pin.
