Cracked Capacitors

Has anyone ever looked into the possibility for laser marking 1812 size X7R ceramic chip capacitors injecting sufficient energy to cause cracking when voltage is applied? If so, what were the findings? We are having failures of caps from one manufa

Capacitor Failure

Since the connection improves when you touch it with a soldering iron, it indicates that the reflow recipe is NOT good. Something may have changed with the termination material requiring a higher peak temperature.

Dennis: These "terminal detach failures" probably are caused by thermal shocking of the components. * Preheat the components * Use a hot air pencil rather than a soldering iron

So you are saying that building to class III is going to prevent failures? I disagree. Class III is trying to hit target condition in every aspect of the production of the circuit board. That my friend does not ensure failures from happening. I see

Hi Randy, No-clean flux needs to be activated in order to burn off the volatiles in the flux. This normally occurs partly during preheat and certainly during the reflow or soldering process. In most hand soldering applications, an operator applies

Hope some of you out there can help me with this one. I am getting feedback from our test department that they are showing opens on solder joints which have visually good wetting. The touch-up operators confirm that the joint looks good. All they do

Intermetallic compounds [IMC]: * Form during the alloying process of some metals. In soldering these are Sn, Ni, Ag, Cu, Au. * Do not accept solder. * Increase in depth in logarithmic proportion to both time and temperature. [So during the solder

Solder joint issue

I would suspect touch-up/repair, unless all your caps are falling off. I know our operators use two irons to solder both sides at the same time. If it's not flay and square, yo may get the defect you are talking about. Another area is co-planari
