Electrically-Caused Fire in Multilayer Circuit Boards

A few months ago, a colleague asked whether he needed a fuse in series with the 5-volt supply on an OEM-supplied printed wiring board. The 5-volt supply to the board was rated about 40 amps. My colleague wanted... Read More...

Fujipoly Introduces Easy Handling Thermal Compound

SARCON® SPG-30A from Fujipoly is an ideal thermal interface option for circuit boards with a large surface area, many components and delicate solder points. The form-in-place silicone compound completely fills ... Read More...

Utilization of Skin Effect for Intra-plane Z-axis Partitioning in Circuit Boards

Skin effect is a term that describes the tendency of the current density of high radio frequency currents to become “crowded” toward the surface skins (surface boundaries) of a conducting material. The extent t... Read More...

Common-mode Field Transfer: Coupling Between Circuit Boards and Conductive Chassis Structures

The myth: Digital (high frequency spectra) circuit boards can be isolated from chassis structures. The reality: Digital (and all high-speed, high-frequency spectra) circuit board are always coupled to chassi... Read More...
