Design in different stages need to set up different points in the layout phase can be used to carry out large grid layout of the device;
For IC, non-positioning connectors and other large devices, you can use 50 ~ 100mil lattice precision layout, and for resistive capacitors and inductors and other passive small devices, can be used 25mil grid points for the layout. The accuracy of the grid is conducive to the alignment of the device and the appearance of the beautiful.
PCB layout rules:
1, under normal circumstances, all components should be arranged on the same side of the circuit board, only the top components too dense, in order to some limited and small heat of the device, such as chip resistors, chip capacitors, paste Chip IC on the bottom.
2, in ensuring the electrical performance of the premise, the components should be placed on the grid and parallel to each other or arranged in order to be neat, beautiful, in general, does not allow the components overlap; components to be compact, the components in the entire layout |
