Although printed circuit boards play an important role in electronic devices, they are not semiconductors. Semiconductors refer to materials whose electrical conductivity is between that of conductors and insulators at room temperature, such as silicon and germanium. They have unique physical and chemical properties and are key materials for making electronic components such as chips. Printed circuit boards are Plattliknande strukturer som består av isolerande material och ledande linjer . Deras huvudfunktion är att tillhandahålla elektriska anslutningar och mekaniskt stöd, snarare än att ha speciella ledande egenskaper som halvledare . Därför, även om de är väsentliga konversationer {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6 {6)
