Vladimir Here are potential causes of MLCCC cracking, and how to tell what caused the crack based on the crack's position, run direction, etc. http://www.ami.ac.uk/courses/topics/0179_fmcc/index.html#3 http://www.syfer.com/category_docs/AN0005_Mechanical_Cracking.pdf And an authorative paper on the subject by John Maxwell, who I think knows more about root causes of cap cracking than anyone: http://www.avx.co.il/docs/techinfo/cracks.pdf And a potential solution to the problem: http://www.avx.co.il/docs/techinfo/mlccflex.pdf Qualify it first. -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Igoshev, Vladimir Sent: Monday, July 14, 2008 1:13 PM To: [log in to unmask] Subject: Re: [TN] Ceramic caps Well, in the case I was asking about none of the failures were in that direction (across the body) but always along it splitting both ends in half either vertically or horizontally. Still a puzzle to me :-) Regards, Vladimir -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Ken Bloomquist Sent: Monday, July 14, 2008 2:05 PM To: [log in to unmask] Subject: Re: [TN] Ceramic caps Right!
