Helloo,

Once in a blue moon, I am experiencing a minor problem of
cracked 1206 resistors.  Resistors are cracked in half and it is
very random (not coming from one mfg or reel batch).
I isolated the source of problem which is coming from our Fuji
CP3 chipshooter pick/place process.   It seems that a resistor
gets cracked in half during the component pick up sequence
from a reel or  placement sequence on the board.
I know the force of nozzle spring acting on resistors during the
pickup and placement cycles is a prime factor for cracking them.

Do you, Fuji experts! have a solution for the problem?

regards
