Parametric/Probecard system - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

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.
