Basic process of the wiring 8 of the PCBs & Manufacturing Services

By tingyuya

??Basic process of the wiring 8 of the PCBs & Manufacturing Services
??PCBs & Manufacturing Services design process is as follows.
??1 draw circuit diagrams
??This is an early work, is a schematic drawing of the completed circuit board design, including generating a netlist. Sometimes, of course, we can not schematic drawing directly into the PCB design system.
??2 planning board Lighting & Electricals
??Draw before the printed circuit board, the user must have a preliminary plan to the board, for example, the board much physical dimensions, using several layers of circuit board, single-sided or double sided, each component what package its installation location.This is an extremely important task is to determine the circuit board design framework.
??3 Set the parameters
??The set of parameters is a very important step in circuit board design. Set the parameters component layout parameters, lamellar parameters, wiring parameters.Generally speaking, there are parameters with their default values can be some parameters in use Protel 99 SE, that after the first set, after almost no need to change the.
??4 loaded network table and component packaging
??Have already been discussed earlier, the network table is the soul of the automatic routing of circuit boards, circuit schematic design and printed circuit board design system interface. Therefore, this step is a very important part. Only the network tables are loaded, may be completed after the automatic routing of circuit board. Components of the package is the shape of the components, for each load component must Outline, in order to ensure the smooth progress of the circuit board wiring.
??5 elements of layout
??Component layout allows Protel 99 SE automatic layout. Good planning board and loaded network table, the user can let the program automatically loaded components, and automatic layout of the components in the circuit board inside the border. Protel 99 SE also allows the user to manually layout. The component layout is reasonable, in order to carry out the next step of the wiring work.
??6 automatic routing
??Protel 99 SE with the world's most advanced meshless, automatically routing technology based on the shape of the diagonal. As long as the parameters set properly, the rational layout of the components, automatic routing success rate is almost 100%.
??7 manually adjust
??So far, not an automatic layout software to the point without manual adjustment. The Autorouting after, there is often unsatisfactory, need to be manually adjusted.
??8 save the file and output
??After completion of the wiring of the circuit board, save the complete the circuit route map files. Then use a variety of graphical output device such as a printer or plotter output circuit board wiring diagram.
