To put in simply, layout actually refers to placement of components in the board. If all the preparation work mentioned above is made well, the Design-Createlist can be created automatically in the schematic diagram, followed by importing of the Design-LoadNets into the PCB Online diagram, and then the components will be seen to stack on the board automatically with flying line in the base pin indicating to connect. Next, the components can be laid out, which requires great effort as this step determines the overall image of the board and the complexity level of the next routing. In the process of layout, initial routing can be tried before the actual routing when it is not certain and full attention should be paid.

PCB employs different resin system and substrate of different materials. Differences in the resin system will lead to significant distinctions in both the activation effect of treating electroless plating copper and the process of treating electroless plating copper. In particular, there are great differences in terms of CEM compound substrate and high-frequency silver substrate, special methods need to be adopted in the treatment of chemical electroless plating copper as the normal way of treating the chemical electroless plating copper tends not to achieve desired results.

Besides, in laying out PCB components of LED switching power supply, it is suggested that engineers should arrange the position of every www.pcbindex.com functional circuit based on the procedure of the circuits. This kind of layout will will the signal flow more effectively and rapidly and make the signals maintain the same direction. In laying out PCB board, the first principle is to ensure routing rate; connection between the flying lines should also be paid special attention; components connected with wires should be put together. The size of loop should be reduced to the minimum extend to stop radiated disturbance of the switching power. |
