In the design, the 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
Printed board size is consistent with the processing of a drawing size ? Ability to meet the PCB manufacturing process requirements ? Whether the anchor tag ?
2 components on a two-dimensional , three-dimensional space with or without conflict ?
3 density component layout is orderly, neat ? Whether all fabric finish ?
4 . Require frequent replacement of components can be easily replaced ? Plug-in boards inserted into the device is easy ?
5 is between the thermal element and the heating element proper distance ?
6 Adjust the adjustable element convenience ?
7 In the heat where needed , installed radiator does not ? Air flow is smooth ?
8 signal flow is smooth and interconnection shortest ?
9 plugs, sockets, etc. and mechanical design are contradictory ?
10. Interference problems have to consider whether the line ?
