Potential of Commercial Wood-Based Materials as PCB Substrate

Area of Science:

• Materials Science
• Sustainable Electronics
• Biodegradable Materials

Background:

• Printed electronics commonly use non-renewable materials like glass-fiber reinforced epoxy.
• There is a growing need for sustainable and biodegradable alternatives in electronic applications.
• Performance challenges exist when transitioning to renewable materials for substrates like printed circuit boards (PCBs).

Purpose of the Study:

• To evaluate the suitability of wood-based materials (cardboard, veneer) as substrates for biodegradable printed electronics.
• To assess the performance of these novel substrates compared to traditional materials.
• To explore potential applications for eco-friendly printed circuit boards.

Main Methods:

• Wood-based substrates (cardboard, veneer) were coated with fire retardant materials.
• Conductive silver ink was screen printed onto the treated substrates.
• Print quality, electrical conductivity, fire performance, and biodegradation were systematically evaluated.

Main Results:

• Screen printing of conductive silver ink on wood-based substrates was successful.
• The fire-retardant coating improved the fire resistance of the materials.
• Electrical conductivity and biodegradation properties were assessed for potential applications.

Conclusions:

• Wood-based materials like cardboard and veneer show potential as biodegradable substrates for printed electronics.
• These materials are suitable for applications utilizing screen printing, such as in environmental analytics.
• Further development could enable wider adoption of sustainable materials in printed circuit board manufacturing.
