printed circuit board IEEE PAPERS-2020
A printed circuit board, or PCB, is used to mechanically support and electrically connect electronic components using conductive pathways, tracks or signal traces etched from copper sheets laminated onto a non-conductive substrate
created an electrical path directly on an insulated surface by printing through a stencil (a shape cut into a board or paper) with special ink that could conduct electricity, just like wires could. This method was called “printed wiring” or “printed circuit.”

Abstract This paper presents a new cost-effective method for the production of air filled SIWs (AFSIW) in conventional printed circuit board (PCB) substrates with a CO2 Laser and how they can be implemented with standard PCB technology(The foil prevents polymer shear.) Thus, the base of the layer in the multilayer printed circuit board experiences internal stress associated with its compos- ite structure. If some of the copper is lost on etching, this internal stress expresses itself in deformation of the base
