Description

Methods that can improve the efficiency of electronic component layout

technical field

The invention relates to an electronic component layout technology, in particular to a method for enabling users to conveniently select required electronic component numbers and improving the layout efficiency of electronic components.

Background technique

With the rapid development of electronic technology, electronic products have been widely used in every family and become inseparable from people. For example, electronic devices such as mobile phones, digital cameras, computers, and MP3s that people like. However, in the printed circuit board (Printed Circuit Board, PCB) manufacturing process of these electronic devices, from design, circuit drawing, structural drawing, parts placement, drawing layout (Layout) drawing to printed circuit board, until finally becoming an electronic product, often Takes a long time to complete. So companies are constantly coming up with new technologies to shorten the R&D process of electronic devices.

Generally speaking, printed circuit boards are completed by the cooperation of electronic engineers, structural engineers and layout engineers. Figure 1 shows the development and design process of printed circuit boards contained in commonly used electronic equipment. As shown in the figure, first, in step 101, the electronic engineer designs the circuit diagram of the electronic device, and converts it into a layout diagram after drawing; then in step 103, asks the structural engineer to design and draw the structural diagram of the electronic device; Then in step 105, the electronics engineer and the layout engineer work together to place (placement) the electronic components on the circuit board; then in step 107, the layout engineer places the electronic components on the circuit board around Line (Routing) way to connect, complete the design of the layout (layout) diagram.

Finally at step 109, the printed circuit board factory completes the manufacture of printed circuit boards according to the circuit board layout.

In the above steps 101 to 107, the designer uses the drawing software installed on the information device to carry out the development and design of the printed circuit board of the electronic device.

When an electronic engineer uses drawing software to design the circuit diagram of an electronic device, he first converts the circuit diagram file into a layout (Layout) file, and performs the placement of electronic components, as shown in Figure 2, which is electronically placed on a printed circuit board Component placement flow chart.

As shown in the figure, in step 201, the designer designs the circuit diagram of the electronic device by means of drawing software, and converts the drawn circuit diagram file into a layout drawing file; then, in step 203, the designer sets in the drawing software The rules of the printed circuit board in the layout diagram file; then, in step 205, add the electronic components and related connection lines contained in the drawn circuit diagram in the layout diagram file of the printed circuit board; then, in step 207, add Pre-determined important components are placed on the circuit board; finally, in step 209, after other components are manually searched for electronic components belonging to the circuit diagram on the same page one by one, the components are placed on the printed circuit board, and the wiring is checked. Whether the position matches the height shown in the structure diagram and the position of the holes until all electronic components are placed on the circuit board.

However, in the process of arranging electronic components, when the user wants to find the electronic components on the same page in the circuit diagram containing thousands of electronic components, and place them one by one in the printed circuit board, it is very easy to cause wobble. Furthermore, because the types of electronic components are increasing and are very similar, if the designer wants to modify or replace the electronic components in the original circuit diagram, he will not be able to find the required components immediately in the numerous circuit diagram pages. Electronic components can be modified or quickly replaced, thus prolonging the development time.

As mentioned above, the layout method of commonly used electronic components is no longer suitable for electronic products with short service life, so there is an urgent need for a method that can improve the layout efficiency of electronic components and increase the speed of placing electronic components; moreover, when electronic engineers change When the original circuit diagram is used, the circuit diagram or electronic components can also be found immediately for modification or replacement, so as to speed up the research and development.
