What is This Material Called FR-4?

Within the PCB industry, FR-4 materials have long been accepted as “standard” materials. However, their use was not specific to the types of board being designed. For today’s high-speed, high-frequency designs, careful engineering and material selection relative to the resin systems and glass weave styles needed will ensure that a product will work as specified, as designed, and as manufactured. In addition, the finish of the copper used in the signal and power layers also needs to be controlled in order to ensure that loss goals are met.

The Influence of Material Characteristics on High Speed Design Part 2: Roughness and Skew

Copper foil and oxide roughness are also major drivers of insertion loss behavior. As discussed in Part 1 of this article series, the first crucial step to efficacious design and development is understanding how the dielectric material attributes are to be carefully considered when assessing impedance and insertion loss performance. This article by Keshav Amla highlights the importance of considering roughness attributes in this assessment, ensuring a well-rounded approach to addressing impedance and loss, as well as skew, a signal integrity concern of ever-increasing importance.

The Importance of Owning the PCB Stackup Process

In this article, Kella Knack outlines the stackup process, highlighting the importance of taking material issues, structural issues, and performance factors into account from the beginning of the design process. Knack discusses how providing fabricators with proper design documentation that includes precise information enables them to build to specification, ensuring correct functionality while avoiding additional costs for design.

3D Connector Models Enhance Signal-Integrity Analysis

PCB connector suppliers are often tasked with providing connectors that meet today’s high-speed and high-density requirements. In many cases, these connectors also need to maintain signal integrity under harsh conditions. Such models make it possible to simulate how the connector will interface and perform in its surrounding environment. IEH has partnered with Modelithics to offer 3D geometry models for various IEH hyperboloid connector products.
