Mitigation of Pure Tin Risk by Tin-Lead SMT Reflow- Results of an Industry Round-Robin

The risk associated with whisker growth from pure tin solderable terminations is fully mitigated when all of the pure tin is dissolved into tin-lead solder during SMT reflow. In order to take full advantage of this phenomenon, it is necessary to understand the conditions under which such coverage can be assured. A round robin study has ...

Next Best Thing to a Close Shave: Mitigating the Risks of Tin Whiskers

If you've been in electronics for any length of time, the phenomenon of tin whiskers is something you've likely heard discussed (maybe in scared whispered tones). Tin whiskers certainly aren't a new problem. In fact, some of the first published reports of the occurrence date back to the 1940's and 1950's. But, over half a century later, we're still talking about it.

Tin Whiskers: Risks with Lead Free | Part I

Tin (Sn) metal displays the characteristic of growing "tin whiskers" from pure tin coatings (most actively on relatively thin, electrodeposited or immersion tin coatings), usually months or years from the initial deposition of the tin. Tin whiskers are electrically conductive, filamentary, single crystals of white (beta phase) tin. These filaments ...

Tin Whiskers: Mitigation with Conformal Coatings | Part II

One of the two basic risks of employing the commercially accepted, Restriction of Hazardous Substances (RoHS) compliant, lead-free (Pb-free) electronics is the threat to the electronics reliability from the growth of tin whiskers. The other basic risk deals with Pb-free solder joint reliability.

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 ...

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.

RJ45 connector selective soldering -- Hello professionals! I am quite new to selective soldering and i have been trying to get rid of solder bridges when soldering RJ45 connector. Seems like i got to point where 1/3 of soldered connectors doesn't have any bridges but other 2/3 have. Our company has Ersa Versaflow 3 selective soldering system. I have now tried with different size of nozzles, from small nozzle to big 18/20 nozzle (only like dipping whole connector at once) but seems like i cannot get better results. I have also tried different soldering times and preheating temperatures. I have also added flux etc. But seems like nothing helps... What to try next? Does anyone here have solved problem like that and could have some parameters what to try to get rid of solder bridges? Thank you. :)
