According to AEM, Inc., Sn/Pb re-plating process inhibits tin whisker growth in components for mission critical and life sustaining applications It also avoids thermal shock damage to surface-mount components due to hot-solder dipping.
The company has announced a hirel-qualified Sn/Pb (tin/lead) conversion process that is designed to mitigate the formation of tin whiskers in surface-mount components. The AEM process was created to eliminate potential damage to sensitive electronic devices caused by conventional hot-solder dipping while ensuring that converted component terminations contain a minimum of 5% Pb as verified by SEM/EDS and XRF inspection methods.
AEM’s Sn/Pb conversion process is best suited for chip-scale passive components, including capacitors, inductors, resistors, ferrite chip beads, fuses, resistor arrays, capacitor arrays, bead arrays and many molded body passive and active surface-mount component types. This process includes 100 percent adherence to visual and mechanical inspections per applicable EIA guidelines, including sample solderability, leach resistance, terminal strength, and destructive physical analysis (DPA) screening
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
