Cracked ceramic chip capacitors.

DST, What was the crack signature? Was the crack parallel with the internal electrodes or 45� with the terminal electrode? It is also important to determine the orientation of the failed caps on the PCB (in regards to depaneling). Perhaps the cap

I was approached by the comp. suplier to change the capacitors that I currently used. No change in elect. charateristic, but only on : a) change of palladium to nickel base inner electrode b) outer electrode material i.e. from silver to copper. Que

Dear all, First, I'd like to thank every one of you who have been a great help for my last questions. Then, I have heard that in multilayer ceramic capacitors, each layer of ceramic was about 3 micrometers at least. When adding the layer (which I d

Hi, The ROHS compliant parts are usually Matte Tin on the outer terminal plating. There are also 2 further types of metal on the average chip cap - the undercoat metal of the outer electrode & the inner electrode. These are usually the same & are

No luck yet. Also cannot buy a Cent electrode motor from manufacturer. Anybody know of sources where we can buy spares for TP-9. Thanks

When designing a PCB to accommodate an intrusive reflow narrow profile connector (electrode rectangular) with specific dimensions, you'll need to consider the pad size, hole size, and other factors to ensure proper solderability and mechanical stabil

Re: moisture in pcb's how is it measured

Hi! Stu's method is a half-truth. What it measures is the aggregate of all volatile material with a significant vapour pressure at the baking temperature, not just H2O. Short of very complex methods, it could be complemented by a comparitive measur

Hello. I have a customer that continues to have problems with their bulk cassette feeder. The customer is complaining about shorted parts that result from bulk cassette feeding operations. They are quick to claim that the failure is related to the

Electronics Forum | Fri Dec 20 10:13:38 EST 2002 | davef

The total inductance of a chip capacitor is determined both by its length to width ratio and by the mutual inductance coupling between its electrodes. So, a 1210 chip size has a lower inductance than a 1206 chip. Check with your supplier for recomm
