Can someone offer me some basic guidlines on diagnosing circuit
boards? I am in the process of working on a signal conditioning board
with approximately 10 surface mount IC's (op amps, isolating amps,
instrumentation amps etc). Some of these IC's are blown. I have no
circuit diagram.
My question is with the individual IC's. How feasible is it to test
each IC individually (in circuit) to see if it is functioning
properly? It would seem to me that just touching a multimeter to such
sensitive circuits change the behavior and possibility not give a
correct view of what is really happening (like open loop op amps and
comparators).
Anyway, any guidlines for diagnosing in-circuit IC's??
thanks much - a confused beginner
