I am unable to find a reliable source to determine the amount of package damage allowable on an SMT coil inductor with a ceramic case. Where can I find information of this nature.

Wow. And I thought I was the only one having problem with ceramic capacitors.I too am having problem with cracking ceramic capacitors 1206 package.We changed vendors and still having the same problem. I had to reverify my entire process and I had to

I agree with all of the previous comments. 1) Here are a few things to keep in mind when cleaning with water. To effectively clean, any liquid must wet the surface. By itself, water has a surface tension of 70 dynes/square cm. This is relaively hig

I have some CERSOT-23 transistor packages with castellated terminals. The 4th lead (drain castellation) is electrically connected to the top of the device by the castellation. The castellation goes up the ceramic body and contacts the metal package

Histroically we have designed our pcb panel configurations around the v-score format. The QA Dept of our company is is suggesting that we revert back to tab-routing as away to avoid damage to senistive components like large package ceramic capacitors

We have problems with voids when we solder lids to ceramic flatpackages. The sealring of the package is gold(100 micro inches or 2.5 micro meters)with a underlayer of Nickel The solder is attached to the lid (preform) and the solder material is Au/S

Dave Frankly, I think you may be barking up the wrong tree. Like DaveF, I suggest that the process would be horrendously expensive with masking and so on. The $64,000 question is whether what you propose will serve any useful purpose. I venture to

We all know that Engineers are human and consequently may make errors when creating pick and place programs. (e.g. program a wrong part number for a given reference designator) Usually that is easy to detect since the wrong component is a differnt p

You seem to pretty far from shore to begin thinking about boats and floatation devices. Most laser trimmers are used by: * Semiconductor fabricators * Resistive component fabricators * Hybrid circuit assemblers Component fabricators and hybrid [

David, There was a thread going on the IPC TechNet about exactly the same thing... The ratio that was posted is: Less than, or equal to 30-grams per square inch Which means if you weighed a part and it is 30-grams, you'll need .033" of surf
