MW PCBs
MW PCBs typically stands for "Microwave Printed Circuit Board." These are specialized printed circuit boards designed to work in microwave frequency ranges, which generally encompass frequencies from 300 MHz (megahertz) to 300 GHz (gigahertz). MW PCBs are engineered to have specific electrical and mechanical properties to handle the unique challenges presented by high-frequency signals.

Wireless products, such as advanced communications systems for base stations, radar, global positioning, and handheld devices for medical and industrial applications, incorporate radio frequency (RF) and microwave (MW) circuits. BSI collaborates closely with your product design team to ensure that the project meets cost/performance targets by providing details on material options, relative costs, and design for manufacturability (DFM) considerations. When producing radio frequency PCBs, it is crucial to consider signal control through (i) material types and characteristics (loss tangent/Df and dielectric constant/Dk), (ii) low profile copper foils, (iii) weave styles, and (iv) copper circuitry layout, as all these factors significantly impact the finished product's performance.
