Lignin, a biopolymer formed in the cell walls of plants, is a by‐product of paper manufacturing. In research at IBM, it was incorporated into a resin used in the fabrication of printed wiring boards (PWB) for the microelectronics industry. The resin had physical and electrical properties similar to those of current laminate resins. PWBs fabricated from the lignin‐based resin passed most of the standard physical, electrical, and reliability tests for an “FR4”‐grade laminate. A comparison of the lignin‐based resin and current resins via life‐cycle assessment indicated up to 40% lower energy consumption for the biobased resin. Large‐scale manufacture of lignin‐based resins would require an inexpensive source of lignin with low ionic contamination.
