Tin Whiskering on PCBA Capacitors in Storage (Inside ESD Bag, Inside a Sealed Cardboard Box)

The tin whisker failures investigated in this paper were found on functional RoHS-compliant hardware. The samples were not conformal coated. This paper will document the conditions associated with the whisker formation under the following conditions; tin

Electrostatic Theory of Metal Whiskers.

Metal whiskers often grow across leads of electric equipment and electronic package causing current leakage or short circuits and raising significant reliability issues. The nature of metal whiskers remains a mystery after several decades of research. Here, the existence of metal whiskers is attributed to ...

Whisker Formation Induced by Component and Assembly Ionic Contamination

This paper describes the results of an intensive whisker formation study on Pb-free assemblies with different levels of cleanliness. Thirteen types of as-received surface-mount and pin-through-hole components were cleaned and intentionally contaminated with solutions containing chloride, sulfate, bromide, and nitrate. Then the parts were assembled on double-sided boards that were also cleaned ...

Strategies To Mitigate The Tin Whisker Phenomenon

The tin whisker phenomenon is a failure mode associated with all electronic devices that use a number of low melting point elements (e.g., Sn, Cd, In) in operations such as soldering. Recognized many years ago, the problem was minimized by adding lead, now identified as a hazardous substance and banned

A New (Better) Approach to Tin Whisker Mitigation

Most of the electronics industry by now knows about tin whiskers. They know whiskers are slim metallic filaments that emanate from the surface of tin platings. They know these filaments are conductive and can cause shorts across adjacent conductors. And they know that these shorts can cause some really bad failures (see nepp.nasa.gov/whisker/ for a list longer than you need). But, with all of this ...

Yamaha M20 -- We have a D1429 Choke Pressure Error. The display shows 564 greater than 350. Our vacuum is good on all 6 heads. Does anyone know how to remedy this?? It has been randomly dropping parts all over the boards. Big mess! Thanks for any help you can bring!

Nordson FX 940 Ultra Nytvision bottom camera -- Has anyone been able to get the bottom camera option to work on Nordson FX 940 Ultra Nytvision? We tried three years ago, but they didn't have the software working yet. And their tech support wasn't sure how to get it working. Nordson is discontinuing the FX 940 and we would like to try the extra camera for barcode traceability. But we aren't going to buy from them anymore unless we know it works before purchase.
