In PCB design, layout is an important part . Layout results will directly affect the wiring of results, so it can be considered reasonable PCB design layout is the first step to success.
Layout are two ways , one is an interactive layout , another is automatic layout , usually on the basis of automatic layout adjustment with an interactive layout in the layout can be re- door circuit traces according to the situation distribution , and the two exchanged gates , making it the best layout for easy wiring . After the layout is complete, but also on the design documents and related information return label on the schematic , PCB board makes information about the schematic is consistent with the order in the next filing, design changes can be synchronized together , while the simulation for information to be updated , which allows for the electrical performance and functionality of the circuit board-level verification.
- Consider the overall appearance
A successful product or not, it is necessary to pay attention to the intrinsic quality , and second, taking into account the overall appearance , both of which can be more perfect that the product is successful. In a PCB board layout elements required to be balanced, density and orderly , not top-heavy or a head sink .
- Check the layout
PCB size is consistent with the processing of paper sizes ? Ability to meet the PCB manufacturing process requirements ? Whether the anchor tag ?
Components on a two-dimensional , three-dimensional space with or without conflict ?
Density component layout is orderly, neat ? Whether all fabric finish ?
Require frequent replacement of components can be easily replaced ? Plug-in boards inserted into the device is easy ?
Profile between the thermal element and the heating element proper distance ?
The adjustable element convenience ?
The need to heat the place , installed a radiator does not ? Air flow is smooth ?
The signal flow is smooth and interconnection shortest ?
Are plugs, sockets, etc. and mechanical design conflicts ?
Interference problems have to consider whether the line ?
