PCB MATERIALS

The layers beneath
printed circuit boards.

Resin chemistry, reinforcement and composite formats. One connected development program.

A CONNECTED MATERIAL PLATFORM

Different roles.
One material system.

Explore the resin, prepreg and core formats at the center of Lignity’s PCB development program.

MATRIX CHEMISTRY

The chemistry that brings the system together.

The resin matrix binds the reinforcement and contributes to the composite’s electrical, thermal and mechanical behavior.

QUESTIONS ABOUT THE PLATFORM

Start with a clear understanding.

Which PCB material formats does Lignity focus on?

Lignity’s platform connects lignin-based resin systems, B-stage prepregs and C-stage laminate cores. Each format has a distinct role in the PCB stack-up.

How does the material approach relate to PCB manufacturing?

The program addresses familiar PCB formats and manufacturing considerations, including impregnation, lamination, copper adhesion and downstream processing.

How can we discuss an application or trial?

Contact Lignity with your application, material format and relevant process requirements. Together we can define the scope, samples and schedule for a focused collaboration.
