Electronics
Printing processes such as silk-screening and photolithography are used in electronics to produce printed circuit boards and integrated circuits. Some common substrates used are;
 * Glass-reinforced epoxy, eg FR-4 board
 * Ceramic-PTFE laminate, eg 6010 board
 * Alumina ceramic
 * Silicon
 * Gallium arsenide
 * Sapphire
 * Quartz
