Altium Focuses on the Designer First

May 22, 2017 | Judy Warner, Altium

A few months before Judy Warner joined Altium, while she was still with I-Connect007, she sat down with Lawrence Romine to discuss the company’s drive to satisfy the individual PCB designer, and not necessarily the OEMs who employ them. Romine also explains what sets designers and engineers apart from the average person, and why some Altium users have a different primary EDA tool, but use Altium when they need a design done fast.

Woven Glass Weave Effect: Electrical Concerns and Remedies

May 17, 2017 | John Coonrod, Rogers Corporation

The idea of glass weave effect has been around for many years, and it is a topic that is somewhat controversial. In theory, the glass weave effect is a concern that the structure of the glass fabric can have a negative influence on high-frequency or high-speed digital circuit performance. One concern for the glass weave effect is that if a critical circuit conductor is perfectly aligned to the pattern of bundles and open areas, the conductor will experience different Dk in small isolated areas. It is possible at very high frequencies or extremely high speed digital rates that these isolated Dk differences could have an influence on the circuit performance.
