Investigation of PCB Failure after SMT Manufacturing Process

An ACI Technologies customer inquired regarding printed circuit board(PCB) failures that were becoming increasingly prevalent after the SMT (surface mount technology) manufacturing process. The failures were detected by electrical testing, but were undetermined as to the location and specific devices causing the failures. The failures were suspected to be caused predominately in the BGA ...

Latent short circuit failure in high-rel PCBs caused by lack of cleanliness of PCB processes and base materials

Latent short circuit failures have been observed during testing of Printed Circuit Boards (PCB) for power distribution of spacecraft of the European Space Agency. Root cause analysis indicates that foreign fibers may have contaminated the PCB laminate. These fibers can provide a pathway for electromigration if they bridge the clearance between nets of different potential in the presence of humidity ...

No-fault-found and intermittent failures in electronic products

This paper reviews the possible causes and effects for no-fault-found observations and intermittent fail- ures in electronic products and summarizes them into cause and effect diagrams. Several types of intermittent hardware failures of electronic assemblies are investigated, and their characteristics andmechanisms are explored. One solder joint intermittent failure case study is presented. The paper then discusses when no-fault-found observations should be considered as failures. Guidelines for assessmentof intermittent failures are then provided ...

EMI-Caused EOS Sources in Automated Equipment

Electrical overstress causes damage to sensitive components, including latent damage. A significant source of EOS is high-frequency noise in automated manufacturing equipment. This paper analyses sources of such noise, how it affects components and how to mitigate this problem.

Nitrogen Reflow leaving residue on Solder Joints -- When using nitrogen during reflow with a water washable RELO paste, we see a residue left on the solder joints that is not present when nitrogen is off. It is enough that we must wash the boards prior to AOI. Does anyone experience this?

Bad solder under SMD electrolytic caps -- Hello ! I've noticed some hardening and partial non-melting in one project, under SMD electrolytic caps. All other components and solder joints are fine on this board. I use Interflux LMPA solder paste (low melting point). I have a theory. The caps are located in board area, which has no planes on top/bottom layers. And the pads are small and mostly hidden under the cap. Could it be that the cap is shielding the heat and there is not enough to melt all the joint ? Also, maybe the lack of heat disturbs the flux flow ? I think I have to make pads bigger so there will be more heat coming in.. Has anybody seen similar behaviour / problems ?
