All,
I have a device parametric system which
uses a probecard. I would like to have a system(
build some known value capacitors/resistors) on
the probe card to measure/qualify) the caps and
resistors we have in our technology. Is this a feasible
way to qualify our production parametric system?Is
this typically used in the industry?
Any advise
would be appreicated deeply.
thanks
kamal

Honestly, your best bet is to measure that stuff
before you put it on the board. The last company
I started used MyData pick and place machines which
would electrically test each component before it
was placed. That way, you know the part is good
when you put it down. Once in circuit, you can do
a signature analysis on a part to see if it "looks
rigt", but there really isn't a good way to check
its absolute value unless you can isolate it.
