PCB (SINGLE SIDED AND DOUBLE SIDED BOARD) (PRODUCTION CAP: 6000 SQ.MT./DAY)
[EIRI/EDPR/4696] J.C.: 2913XL
PCB Stands for "Printed Circuit Board." A PCB is a thin board made of fiberglass, composite epoxy, or other laminate material. Conductive pathways are etched or "printed" onto board, connecting different components on the PCB, such as transistors, resistors, and integrated circuits.
In other words, A printed circuit board (PCB) mechanically supports and electrically connects electronic components using conductive tracks, pads and other features etched from copper sheets laminated onto a non-conductive substrate.
Multilayer PCB is a type of circuit board that contains three or more layers of conductive material. These boards increase the available area for wiring. Whenever we talk about a number of layers, it means we are considering a number of conducting patterns on the board. Multilayer PCBs are normally Rigid PCB. It is because it is very difficult to create it in a flexible format.
The number of layers depends on your needs. So layers could be up to 100. However, 4 to 8 layer PCBs have common usage in various applications. Circuitry gets complex when layers increase. So you can customize different numbers of layers according to your needs.
