Jiva and Eco-Technilin created Soluboard, a revolutionary bio-composite material manufactured with Eco-Technilin’s FlaxTape.


Soluboard to redefine the way PCBs are manufactured

The substrate currently used in the printed circuit board industry is constructed using epoxy resin and fibreglass. This means that the only recycling method for PCBs involves shredding them down and incinerating them in order to extract the precious metals used in these boards. This is a very inefficient process with substantial loss of these metals during reprocessing as well as releasing toxins such as cyanide, mercury and dioxins into the environment.

Currently patent-pending, Soluboard is intended to replace the current standard material used in the industry (FR-4). It is a competitively priced, fully-biodegradable material that can rival the outdated fibreglass and epoxy alternative. The primary ingredient in the composite material is Eco- Technilin’s FlaxTape, a patented tape consisting of unidirectional flax fibres with a lower density than alternative carbon and glass fibres. The unidirectional orientation of the flax fibres means they can be efficiently arranged to form the multilayer bio-composite structure of Soluboard, giving the material strong mechanical properties. FlaxTape is also ideal for manufacturing lightweight products with improved mechanical properties and a lower environmental impact.

Key Benefits:
> A direct replacement for FR-4 with the same price and improved sustainability
> Decreasing the impacts from Waste Electronic and Electrical Equipment (WEEE)
> Decreasing the carbon footprint generated by electronic and electrical products
> Increased yields of precious metal recovery from PCB recycling
> Improved incentives for electronics manufacturers to internalise recycling

With nearly 45 million tonnes produced last year, electronic waste is now the fastest growing waste stream in the world. Dissolving a circuit board made from Soluboard allows for 90% of its components to be reclaimed and then either repurposed or recycled in an overall much more efficient process.

This innovation has been selected as a finalist for the JEC Innovation Awards 2019 in the Sustainability category.

The JEC Innovation Awards - organized by the JEC Group - are recognized as the industry’s most prestigious awards that identify, promote and reward the most innovative composite projects worldwide. The award winners will be announced during JEC World 2019 on 13 March at 4.30pm. Their associated partner is Eco-Technilin SAS.
