Post subject:  Copper PCB design

Circuit design of the printed circuit board, the designer will meet the problem of large area PuTong basically. The widespread application of copper commonly used on the printed circuit board has two kinds. a
Kind is a large copper, copper is a kind of grid. Its effects are different: one for heat dissipation, one for reducing interference shielding (and possibly some other aspects of the role).
It is a big copper sheet, or copper clad 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 in the production of PCB
Process, during the etching process of a certain influence on the quality of the PCB, thereby, in the production of PCB, the engineering data processing link, usually between the small
Gap is 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
Workload, reduce the efficiency, prolong the process of PCB. Designers at design time, therefore, if the lingering effects of the plate velocity factors into consideration, the
Yao of the PCB process will be optimized, the designer's research and development cycle.
