RF PCB Layer Stackup – “Pure Build” Versus “Hybrid Build”

A “Pure build” refers to a multilayer PCB material construction that is composed of the same type of material throughout the stackup.
A „Hybrid build“ could use a mix of Isola PCL370HR high performance material 180°Tg with high-frequency material Isola I-Tera MT40.

The reasons for using a hybrid construction in RF multilayer PCB designs are typically driven by cost, reliability, or electrical performance.

When designs feature a number of noncritical circuit layers, these can usually be built on the more cost-friendly PCL370HR material only using high-frequency RF materials on the critical circuit layers.

Hybrid construction is becoming more popular as technology evolves, but hybrids bring both benefits and challenges that need to be understood. Working closely with the PCB fabricator will ensure the best construction methodology that balances RF performance and PCB manufacturability.

SQP International Towards 5G – Shaping our Europe’s digital future

The “fifth generation” of telecommunication systems, or 5G, will be one of the most critical building blocks of our digital economy and society in the next decade. SQP International has taken significant steps to participate in global developments towards this strategic technology.

High speed digital printed circuit boards are key components for devices processing or transmitting high data rates. Typical applications are IC test systems, 5G base stations, internet switches, IoT devices and high speed computing. These systems operate in many cases with data rates of 10Gbit/s or more.
