ESL ElectroScience and ESL Europe manufacture screen-printable pastes such as thick-film paste conductors, dielectrics and resistors (also known as thick-film inks, paints or coatings), ceramic tape systems, and fired parts such as porous alumina and zirconia cover plates, SOFC substrates, MEAs, and both anode-supported and electrolyte-supported fuel cells. These advanced materials find application in hybrid microcircuits and multilayer microelectronics, electronic components such as inductors, capacitors and transformers, heaters on steel or other substrates, plus low and high temperature co-fired ceramics (LTCC and HTCC). In addition, applications include photovoltaic solar cells, SOFC and other fuel cells, temperature/pressure/gas sensors, sealing glasses and other thick-film interconnect or metallization needs.
