Isola Laminate Prepreg High TG PCB Circuit Board Design Prototype

Specification:

370HR Laminate and Prepreg
370HR is a high performance 180°C glass transition temperature
(Tg) FR-4 system for multilayer Printed Wiring Board (PWB)
applications where maximum thermal performance and reliability
are required. 370HR laminate and prepreg products are
manufactured with a unique high performance multifunctional
epoxy resin, reinforced with electrical grade (E-glass) glass fabric.
This system provides improved thermal performance and low
expansion rates in comparison to traditional FR-4 while retaining
FR-4 processability.
In addition to this superior thermal performance, the mechanical,
chemical and moisture resistance properties all equal or exceed
the performance of traditional FR-4 materials. The 370HR system
is also laser fluorescing and UV blocking for maximum compatibility
with Automated Optical Inspection (AOI) systems, optical positioning
systems and photoimagable solder mask imaging.
370HR has proven to be best in class for sequential lamination

Radio frequency (RF) and microwave PCB’s are a type of PCB designed to operate on signals in the megahertz to gigahertz frequency ranges (medium frequency to extremely high frequency). These frequency ranges are used for communication signals in everything from cellphones to military radars. The materials used to construct these PCB’s are advanced composites with very specific characteristics for dielectric constant (Er), loss tangent, and CTE (co-efficient of thermal expansion).

High frequency circuit materials with a low stable Er and loss tangent allow for high speed signals to travel through the PCB with less impedance than standard FR-4 PCB materials. These materials can be mixed in the same Stack-Up for optimal performance and economics.
