design process

The basic design process of the circuit board can be divided into the following four steps:
The design of circuit schematic diagram
The design of circuit schematic diagram is mainly the use of Protel DXP schematic editor to draw schematic diagram.
⑵ Generate network reports
The network report is the report that shows the link relationship between the circuit principle and the various components. It is the bridge and link between the circuit schematic design and the circuit board design (PCB design). Through the network report of the circuit schematic diagram, it can quickly find the connection between the components, so as to provide convenience for the later PCB design.
⑶ Design of printed circuit board
The design of the printed circuit board is what we usually call the PCB design, which is the final form of the conversion of the circuit schematic diagram. The relevant design of this part is more difficult than the design of the circuit schematic diagram. We can complete the design of this part with the help of the powerful design function of Protel DXP.
(4) Generate printed circuit board reports
After the printed circuit board design is completed, it is necessary to generate various reports, such as generating pin reports, circuit board information reports, network status reports, etc., and finally print out the printed circuit diagram.

The design of the circuit schematic diagram is the foundation of the whole circuit design. The quality of its design directly determines the effect of PCB design.Generally speaking, the design process of circuit schematic diagram can be divided into the following seven steps:
⑴ Start Protel DXP schematic editor
Set the size and layout of the circuit schematic diagram
⑶ Remove the required components from the component library and place them on the working plane
(4) Connect the components according to the design needs
⑸ Adjust the components after wiring
It saves the schematic diagram documents that have been drawn
⑺ prints out the drawing
The size, orientation, and color of the drawing are mainly realized in the "Documents Options" dialog box. Press the Design→Options command to open the "Documents Options" dialog box. In the Standard Styles area, you can set the size of the drawing, click the button, and select A4~ Orcade paper shapes in the drop-down list box.Set the Orientation of the drawing through the Orientation option in the Options section of the "Documents Options" dialog box. Click the button, select Landscape, and set the horizontal drawing.Select Portrait and set the vertical drawing.The setting of drawing Color can be realized in the Options section of the drawing setting dialog box. Click the Border Color block to set the drawing Border Color, and click the Sheet Color block to set the drawing background Color.
(4) Execution of the Design→Options→Change System Font command. The "Font" dialog box pops up. Through the dialog box, the user can set the System Font, the color, the size and the Font used in the System Font.

The Settings of the grid and cursor are mainly implemented in the "Preferences" dialog box. To open the "Preferences" dialog box, execute the Tools→Preferences command.
Set Grid: Select the Graphical Editing TAB in the "Preferences" dialog box that opens. In the Visible Grids column of the Ccursor Grid Options section, select the Line Grid option for Setting Linear Grid and the Dot Grid option for Point Grid (Grid-free).
Set Cursor: Select the Cursor Type option of Cursor Grid Options in the Graphical Editing TAB. There are three Cursor types under this option: Large Cursor90, Small Cursor90, and Small Cursor45. The user can select any of the three Cursor types.

Plate-making technology

PCB board technology, including computer aided manufacturing processing technology, namely CAD/CAM, and light painting technology.The following is the introduction of computer aided manufacturing processing technology
Computer-aided manufacturing (CAM) is the process of processing according to the determined process.All the process requirements mentioned in front of us should make the necessary preparations before light painting.For example, mirroring, welding resistance expansion, process line, process frame, line width adjustment, center hole, contour line and other issues are to be in
CAM process to complete.In particular, small Spaces in user files must be handled accordingly.Because the process flow and technical level of each factory are different, in order to meet the final requirements of users, necessary adjustments must be made in the production process to meet the needs of users
The requirements of all aspects such as precision.Therefore, CAM processing is an essential process in modern printed circuit manufacturing.
What CAM has done
Correction of pad size. Combination of D code.
The correction of the line width, combined with D code.

The minimum spacing should be inspected, between pads and pads, between pads and lines, and between lines.
4. Check the aperture size of the guest.
5. Check the minimum line width.
Pictures of welding to determine the expansion parameter.
7. Press Mirror.
8. Add various process lines and process boxes.
Its width is corrected to correct side erosion.
The adhesive will form the central hole.
Learn to add shape corner lines.

Organization of CAM process
As the popular CAD software on the market as many as dozens of, so the management of the CAD process must first start from the organization, good organization will achieve twice the result with half the effort.
Since Gerber data format has become the standard in the light painting industry, Gerber data should be taken as the processing object in the whole light painting process.The following problems arise if CAD data is used as an object.

1. There are too many kinds of CAD software. If all kinds of process requirements are to be completed in the CAD software, it requires every operator to be skilled in the operation of each CAD software.This will require a long training period before the operator can become a skilled worker to meet the actual production requirements.
This is not economical in terms of time and economy.
2. Because of the many process requirements, some requirements for some CAD software is impossible to achieve.Because the CAD software is to do the design with, did not take into account the special requirements in the process, so can not meet all the requirements.The CAM software is specifically designed for processing,
These jobs are at your best.
The CAM software was powerful, but all operations were performed on Getber files, not CAD files.
If the CAD process is used, each operator is required to be equipped with all the CAD software, and each CAD software has different process requirements.This will create unnecessary confusion for management.
To sum up, CAM organizations should be the following structures (especially large and medium-sized enterprises).
(1) All process processing should take Gerber data as the processing object.
Each operator must master the skill of converting CAD data into Gerber data.
⑶ Each operator must master one or more operation methods of CAM software.
(4) Establish a unified process specification for Gerber data files.
CAM processes can be handled relatively centrally by several operators for management purposes.Reasonable organization will greatly improve the management efficiency, production efficiency, and effectively reduce the error rate, so as to achieve the effect of improving product quality.
