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....

An optimal reflow profile is one of the most critical factors in achieving quality solder joints on a printed circuit board (PCB) assembly with surface mount components. A profile is a function of temperatures applied to the assembly over time. When graphed on a Cartesian plane, a curve is formed that represents the temperature at a specific point on the PCB, at any given time, throughout the reflow process....

The effectiveness of cleaning stencils and misprinted/dirty printed circuit boards can be effectively monitored. This can be done by washing known clean circuit boards and then checking to see if they have stayed clean as a result of the washing process. ...

As chip packaging and interconnectivity have become more dense and operate at higher clock frequencies, physical access for traditional bed-of-nails testing becomes limited. This results in loss of ICT (in-circuit test) fault coverage and higher test fi...

Driven by high-profile regulations compliance like the TREAD Act, warranty management has become a hot topic across industries worldwide. Recalls are costly and time-consuming events that should be avoided entirely. But without adequate process traceability and product genealogy, too many customers will get defective products and too many products will be recalled for repair or replacement even though they are not defective. Both scenarios have enormous implications for the quality-conscious manufacturer that gets rated on the number of recalls it performs - not to mention the enormous direct costs. The core issue is visibility into product quality....
