　　What is Multilayer PCBs

　　Multilayer PCBs are erected by joining all the number of layers and paraphernalia at high temperature and pressure so as to remove any trapped air between the layers. Resin and tenacious material is used to stick the factors and different layers together. You can choose from a number of paraphernalia analogous as fantastic ceramic, library paste glass, or Teflonetc. to make your PCB. The different prepreg and core layers are combined and go through the lamination process taking place at high temperature and pressure that helps to melt the layers together. After that the PCB is cooled down to form a hard and solid board.
