Fast view of electronic part- PCB

A printed circuit board or pcb, is a plate or pcb board used for placing the different elements that conform an electrical circuit that contains the electrical interconnections between them. The main function of this product is to make all kinds of electronic components connected to a predetermined circuit is formed, and acts as a relay transmission, is the key to the electronic interconnect electronic products.

Printed circuit board manufacturing quality not only directly affect the reliability of electronic products, but also affect the overall competitiveness of the system products, so the printed circuit board is called the "mother of the electronic system products." The level of development of the printed circuit board industry in a country or region may reflect the pace of development of the electronics industry and technical standards to some extent.

The most simple printed circuit boards are the ones that contains copper tracks or interconnects pcb board only on one of its surfaces. These kinds of boards are known PCB board as 1 layer printed circuit board or 1 layer PCB.

The most common PCB's manufactured pcb board today are the ones that contain 2 layers, that is, you can find interconnects in both surfaces of the board. However, depending on the physical pcb board complexity of the design (PCB layout), the boards can be manufactured of 8 or more layers pcb board. CCL, copper, prepreg, chemical medicine, anode copper / tin / nickel, dry, inks and other products is the main raw material needed for the production of PCB. The proportion of the cost of raw material costs accounted for 66%, respectively.
