Cracked SMT Capacitors

Electronics Forum | Wed Jun 13 16:13:54 EDT 2001 | Igmar

Have anyone seen this problem: Capacitors (100nF 0805) placed on PCB and then appear cracked after reflow. After reflow, the solder joints look visualy acceptable. Then capacitors fail during testing. When attempting to remove capacitor with hot sol

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

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.

Soldering electronic components like electrolytic capacitors can be some of the most difficult terms in PCB repair. Electrolytic capacitors, like other components, come in two main formats. 1. Through-hole capacitors have long leads designed to pass

I think the suppliers more on the application that the capacitors would be used to.

We sent the sectioned capacitor to our supplier for analysis. So, the results of their analysis is probably in a file drawer someplace.

capacitor voltage rating

Electronics Forum | Fri Jan 10 10:09:42 EST 2003 | mantis

Hi In selecting or substituting a capacitor for use, consideration must be given to (1) the value of capacitance desired and (2) the amount of voltage to be applied across the capacitor. If the voltage applied across the capacitor is t

We are finding cracked capacitors at both first pass and second pass.

How much capacitor offset is acceptable?
