Multilayer Printed Circuit Board. A two layer board has copper on both sides. Conductors on different layers are connected with vias which are copper plated holes that function as electrical tunnels through the insulating substrate.
The four layer multilayer board is most common but some designs use eight or more layers with 20 layers being the most common feasible maximum. Multilayer technology has been producing quality printed circuit boards since 1986. Multi layer boards sandwich additional copper layers between layers of insulating material.
The copper layer is pressed together by the resin layer prepreg.
A printed circuit board or pcb is used to mechanically support and electrically connect electronic components using conductive pathways or traces etched from copper sheets laminated onto a non conductive substrate. Multilayer pcb is a circuit board that has more than two layers. A printed circuit board or pcb is used to mechanically support and electrically connect electronic components using conductive pathways or traces etched from copper sheets laminated onto a non conductive substrate. Multilayer pcb or multilayer printed circuit boards are circuit boards composed of two or more conductive layers copper layers.
