Tin whiskers is a major problem of RoHS Lead-free design, whose components are having pure Tin or Matte Tin. While the precise mechanism for whisker formation remains unknown, it is known that whisker formation does NOT require either dissolution of the metal NOR the presence of electromagnetic field. The mechanisms by which tin whiskers grow […]

Two common noise-related analog phenomena encountered by FPGA digital designs are ground bounce and VCC sag. Ground bounce and VCC sag exist to some degree in almost every board. Normally, if ground bounce occurs on a board, VCC sag occurs as well. Ground bounce occurs when most, if not all, of the bits of the […]

Printed circuit board (PCB) layout design becomes more complex for high-speed system design with high frequency and higher device pin density. A successful high-speed board must effectively integrate the devices and other elements while avoiding signal transmission problems associated with high-speed I/O standards. Because today’s high density CMOS devices feature fast I/O pins, a wide […]

Low-Voltage Differential Signaling (LVDS) is a high-speed, low-voltage, low-power, and low-noise general-purpose I/O interface standard. The low-voltage swing and differential current mode outputs significantly reduce electromagnetic interference (EMI). These outputs have fast edge rates that cause signal paths to act as transmission lines. Therefore, ultra-high-speed board design and differential signal theory knowledge is especially useful […]

Heat generation from silicon microprocessors is highly non-uniform both spatially and temporally, with localized high heat fluxes that vary with the workload. Current electronics cooling technologies based on conduction and convection can potentially cool moderately high heat fluxes by utilizing either novel passive heat transport materials (such as carbon nanotubes) or advanced heat exchangers (such […]

Halogen-Free has recently been hot topic in the electronics industry due to increasing concern over environmental issues. A voluntary initiative has been undertaken by the electronics industry, known as the “Halogen-free Initiative.” This self imposed initiative bans the use of halogenated materials in the manufacture of electronic equipment. Certain types of halogenated materials have a […]
