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 programme 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.
