Dear All, What is the possible root causes of the dendrite growth? How long its take to cause this dendrite growth? Can dendrite growth cause electrical short? Is there any particular location on PCBA that dendrite tend to grow? Thanks, Sean

In the portion of Chapter 1 on Flip Chips, Ken Gallio states (1.8.2.1) "tin/lead solder leaching or dissolving gold and form metal compounds, called dendrites, that greatly reduce joint reliability because of high brittleness." What is the compositi

From battery fires to non-functional charging stations, from dendrites to poor cable connections, electronic system failures have caused massive recalls. Failures are increasing significantly, not because of quality, but because of usage and implementation of technology. As the expected lifetime usage of parts increases and technology applications change, materials, approaches, and test parameters must change as well.

Conformal coating is a material that is applied to electronic products or assemblies to protect them from solvents, moisture, dust or other contaminants that may cause harm. Coating also prevents dendrite growth, which may result in product failure. This paper will discuss the variables that affect the application of conformal coatings, and review in detail those variables that impact the process of selective coating of printed circuit boards.

ACI Technologies was pleased to assist a customer by conducting elemental analysis on several assemblies displaying severe corrosion. Several board assemblies had failed in the field and exhibited areas of corrosion in close proximity to onboard components. The most common source of corrosion on electronic assemblies is residual flux. Fluxes are specific chemistries applied during the soldering process which improve the wetting of the solder to both the pad and component when forming the solder joint. They can be highly reactive chemicals that, if left on the assemblies, can lead to corrosion, electrical degradation, and decreased reliability. In the presence of moisture and electrical bias, flux residue can enable dendritic growth as a result of electrochemical migration (ECM).
