SMTA Europe announces Session 5 Technical Program on Adhesives and Coatings at the “Electronics in Harsh Environments Conference” to be held in Amsterdam, Netherlands, on April 25, 2018.

Significant performance and reliability challenges exist for harsh environment electronics within the automotive, power electronics, oil & gas, and aerospace applications. Under varying harsh operating environments, the life expectancy of electronic components and systems reduces exponentially if they are not designed, packaged, and protected appropriately. Dr. Rakesh Kumar of Specialty Coatings will present on thermally-stable, vapor-phase conformal coating for protection of electronics in harsh environments.

Highly dense assemblies are commonly packaged in designs that are permeable to moisture. While operating in hostile environments, the thickness and coverage variability of conformal coating over components impacts reliability. Phil Kinner of Humiseal will present research that compares and contrasts coating thickness to help the assembler determine optimum levels needed to withstand harsh environments. The attendee will gain insight into coating types, properties and reliability expectations.

Area array components, such as Ball Grid Arrays (BGAs), Chip Scale Packages (CSPs) and Flip Chip (FCs), then to add complexity to conformal coating processes. Previous studies have shown that the presence of conformal coatings under an area array component can induce solder joint failure. Dave Hillman of Rockwell Collins will present on how conformal coatings impact solder joint integrity of these advanced packaging. The research finds that some of the coating configurations degraded component reliability while others improved reliability.

Is There an End in Sight to the Electronic Components Crisis?

07/12/2018 | Neil Sharp, JJS Manufacturing
As new and innovative technology continues to evolve on a daily basis, the need for electronic components has reached unprecedented levels, with passive manufacturers in particular among those struggling to cope with demand. Electronic component shortages are now such an issue that many OEMs are predicting their forecasted growth for 2018-2019 will be thwarted if they are unable to source the parts they need.

It’s Time to Retire ROSE Testing

06/27/2018 | Joe Russeau, Precision Analytical Laboratory, and Mark Northrup, IEC Electronics
Over the last two to three years, there has been considerable discussion within various IPC committees about the role of the ROSE test in today's assembly environment. The transition from predominantly water wash processes to "no clean" has meant the advent of very different flux compositions. The question has been posed as to whether the ROSE test is still a viable option for evaluating PCB and PCBA cleanliness.
