Not completely understood, electrically conductive tin whiskers are crystalline structures between 1-2 millimeters (mm) that can grow from surfaces where tin is used as a final finish; surfaces finished with electroplated tin are particularly susceptible to whisker growth. Although their occurrence was originally documented during the 1940s, no real solution has yet been devised to […]
High-tech electronic systems increasingly regulate automotive management functions for emissions’ controls, fuel systems, fluid monitoring, lighting, and powertrain mechanics, frequently comprised of miniaturized, multi-layer MEMS/Nano packages. Systems’ survival in hostile vehicular environments typified by condensation, corrosive fluids and vapors, excessive temperatures, humidity and prol

Protection of printed circuit boards (PCBs) is most often achieved with either potting or conformal coating. The selection of which method to use depends upon the PCB’s purpose and how much protection it requires. Potting offers the strongest shielding barrier, but is also affected by a range of operational disadvantages that can offset its functional […]
