any advice on smt resistors and capacitor that can survive an explosive shock. the ceramic smts are not, plastic ic's and discretes do fine.

Can anyone help me with the pros and cons of trying to wave solder tantalum and large (1812) ceramic capacitors. I do know that one may see fractures on larger cermaic caps, but have not seen much on the tantalums. Any insight as to what problems I c

Hi We are experiencing serious problem with ceramic capacitors. They are with low electrical resistence and the problem is intermittent. We found some of them with micro cracks but not all. What could be the causes for this problem? We are su

suggest you check the preheat conditioning in the wavesolder process is sufficient, as this is the main culprit for micro-crack CAPs ?

We have had failure due to a leakage in one ceramic chip capacitor. External inspection did not show any obvious damage. Cross section showed a void in the capacitor. The void was an elliptical shape and positioned longitudinal to the length of the c

Flex cracking under the terminations is generally regarded as one of the primary causes of failure of ceramic chips. If you can see cracks in the solder joints from board flex, those chips are certainly strongly suspect, and you must assume there is

We had this problem with 0805 0.1 mF also. This problem was only with this capacitor. We have replaced all these capacitor after the ninth occurrence. My opinion - it is a defect of the manufacturer. Please inform the manufacturer of your capacitor.

Please send us more information about how the glue dots can cause capacitor cracks. I didn�t understand why it could happen. Thanks
