Circuit design of the printed circuit board, the designer has to deal with a large area basically PuTong problem. The widespread application of copper commonly used on the printed circuit board has two kinds.
Is a kind of copper, copper is a kind of grid. Its effects are different: one for heat dissipation, a shield for reducing (and possibly some other aspects of the role).
That exactly is reply to copper, copper or grid? Depending on the board to the specific design. But based on the system board factors to consider, if the performance is not particularly need coated mesh copper suggested that designers should reply to copper sheet. Because there will be a small gap on copper mesh, these small gaps will be in the process of making PCB, during the etching process a certain influence on the quality of the PCB board, thereby, in the production of PCB, the engineering data processing link, generally small gap will be removed. But it is a pity that the existing CAM software basically can't rid of 100% of the small gap, which requires engineers to operate manually, thus greatly increased the workload, reduces the efficiency, prolong the process of PCB. Designers at design time, therefore, if the lingering effects of the plate velocity factors into consideration, so the PCB process will be optimized, the designer's research and development cycle.
