The design of the PCB circuit board is based on the circuit schematic and realizes the functions required by the circuit designer. The design of the printed circuit board mainly refers to the layout design. It needs to consider the layout of external connections, the optimized layout of internal electronic components, the optimized layout of metal wiring and vias, electromagnetic protection, heat dissipation, and other factors.
The third quarter PCB industry is still booming. Due to the recovery of the component industry in the second half of 2009, the base number is large, so the growth of PCB sales in the second half of this year will fall back, but the industry boom continues to Q3 is not a problem. The increase in demand for flexible PCBs will also be stable. This week PCB circuit board quoted at 350.00 yuan/square meter.
