Low-Loss Dielectric Materials Improve PC Boards

Low-loss dielectric materials are available. The hydrocarbon- based, fiber-reinforced composite sheets can be applied to printed circuit boards and IC chip packaging. The material has a very low dielectric constant and low dissipation factor up to GHz range frequencies, and is advantageous for emerging high-frequency electronics applications as a printed circuit dielectric sheet.

Optimum Fastener Selection for Internal Pumping in Vacuum Systems

The use of fasteners inside of vacuum chambers, while necessary for obvious reasons, can present a number of problems resulting from trapped volumes. Trapped volumes of gas, typically air trapped during assembly, within vacuum chambers are not easily found and can be difficult to pump out, often appearing later as “virtual leaks”. Fasteners also, due to their helix design, have a large surface area relative to their size, creating an un-exposed water-retaining surface. Fortunately there are optimal fastener configurations that address these issues.
