Cracks: The Hidden Defect
Aug 15, 2019 | John Maxwell
Cracks in ceramic chip capacitors can be introduced at any process step during surface mount assembly. Thermal shock has become a "pat" answer for all of these cracks, but about 75 to 80% originate from other sources. These sources include pick and place machine centering jaws, vacuum pick up bit, board depanelization, unwarping boards after soldering, test fixtures, connector insulation, final assembly, as well as defective components. Each source has a unique signature in the type of crack that it develops so that each can be identified as the source of error....
Hermetically Sealed SMD Tantalum Capacitors

manganese dioxide or conductive polymer cathode. Higher stability is achieved by placement of the capacitor into an SMD case filled by an inert atmosphere and hermetically sealed. The long term stability testing performed on such hermetically sealed capac...
