Graphics card PCB how to distinguish between 4 or 6 layers
Printed circuit board design mainly refers to the layout design, need to consider the layout of external connections, the optimization of internal electronic components layout, metal wiring and through-hole optimization layout, electromagnetic protection, heat dissipation and other factors.
What is PCB? PCB is Printed Circuit Board shorthand, the Chinese name for the printed circuit board, also known as printed circuit boards, printed circuit boards, is an important electronic components, is the support of electronic components, electronic components is the electrical connection provider. Because it is made using electronic printing, it is called "printed" circuit board.
To see how many layers of PCB, through the observation of the hole can be about to identify the motherboard and graphics card used on the four-tier board is the first, the fourth layer of the line, the other layer of another use (ground and power ).
Under normal circumstances, multi-layer circuit board connection through the hole and blind hole technology, motherboard and graphics cards are mostly used 4-layer PCB board, and some are using 6,8 layer, or even 10 layers of PCB board.
PCB thickness and layer number is not directly related. 6 layers can also be pressed to be thinner than the 4 layer. The key to see the PCB manufacturers of PCB product thickness of the definition of the number of specifications
