Dun you have a LCR meter? or mebbe your side calls it a LCZ meter??? whatever...it measures Inductance, Ohms, Capacitance...check-it-out-manz...

Should be some numbers on the top of the other two. If you can read them we can get you the right part info. it also looks as though you have some trace and pad damage that will require repair prior to you putting down new part. Or you can remove

What kind of boards are they? Unless they are very simple boards, you won't be able to just replace every TH component with a SM equivalent. The inherent LCR characteristics of the board will change I think the normal way would be not to change the

First, you cannot measure capacitors once they are soldered onto the board. Second, why must you measure? Verify your machine set up by using intelligent feeders (if your machine has them) or a checklist, preferably by two people. If you cannot trus

Since we are on the topic, What we do over here, is to get SMT Technical to machine pick&place "sample component layouts" onto double-sided tape, which in turn is placed onto an actual PCB... QA will take that double-sided tape sample, and using an

Use an "LCR" (L= inductance, C= capacitance, R= Resistance)meter. There are several name brands to choose from (Fluke, etc.) Hand held units are relatively inexpensive. In fact, you may consider having more than one available. Receiving inspection s

We hand solder them also. From CapSite 2004 ... "Whether polystyrene capacitors will really go away any time soon is not certain. I have been warned of polystyrene�s demise "in a few years" for over a decade now, and yet it is still available. The

Have you verified the measurements on the bench with an LCR meter? Chances are you are experiencing aging with these ceramic caps. We have similar issues with X5R and X7R caps. You will see the effects of aging with returns from the field as well

Is this a new assembly/new test fixture/program? Or is this an existing assembly that is suddenly exhibiting this failure? Capacitors measured in circuit will not necessarily measure their correct values. Active components in circuit will be affec
