What is Multilayer PCBs
Multilayer PCBs are built by joining all the number of layers and materials at high temperature and pressure so as to remove any trapped air between the layers. Resin and adhesive material is used to stick the components and different layers together. You can choose from a number of materials such as exotic ceramic, epoxy glass, or Teflon etc. to build 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.
Sideplating is the metalization of the board edge in the PCB filed. Edge plating, Border plated, plated contour, side metal, these words can also be used to describe the same function.
Half-cut Castellated Holes
Castellations are plated through holes or vias located in the edges of a printed circuit board. are indentations created in the form of semi-plated holes on the edges of the PCB boards.These half holes serve as pads intended to create a link between the module board and the board that it will be soldered onto.
