Sep 07, 2016

Printed circuit board, also known as printed circuit boards, is a provider of electronic components and electrical connections. Has a history of more than 100 years of its development, and its design is layout used circuit board's main advantage is greatly reduce errors in wiring and Assembly, increasing the level of automation and labor rate.

According to the PCB layer can be divided into single-sided, double-sided, four-layer Board, six boards and other multilayer PCB.

As printed circuit boards are not end products in General, therefore, in the definition of the name slightly confused, for example: PC motherboard, motherboard, and cannot be called a circuit board, main Board circuit board is in, but it's not the same, so assessing the industry both related I cannot say the same. For example: because parts of integrated circuits mounted on a circuit board, thus the news media called him the IC Board, but he is not equivalent to a printed circuit board. We usually say that the printed circuit board is the bare Board-that there are no components on the circuit board.
