PCB (printed circuit board), Chinese name of the printed circuit board, also known as printed circuit boards, printed circuit boards, electronic components are important, is the support of electronic components, electronic components are provided by the electrical connection. Since it is produced using electronic printing, so called "print" circuit board.
Printed circuit board design is based on the schematics, circuit designers to achieve the required functionality. Printed circuit board layout design mainly refers to the need to consider a variety of factors external connector layout, optimizing the layout of the internal electronic components, optimize the layout of metal wires and vias, electromagnetic protection, thermal dissipation. Excellent layout can reduce production costs, to achieve good performance of the circuit and thermal performance. Simple layout can be achieved by hand, complex layout needs the computer-aided design (CAD) implementation.
PCB circuit when the plate is printed directly on the CCL, and then welded components in printed class.
