[Means to solve the problem]

The structure of the printed circuit board of this invention is the display code of the electronic components mounted on the printed circuit board. In the structure of a printed circuit board with silk printing representing Equipped with a printing method that distinguishes and prints silk-printed markings for hand-feed parts and machine parts. It is something.

[0006]

[Effect] According to this idea, a system that represents the display code of electronic components mounted on a printed circuit board. By distinguishing between manually inserted parts and machine parts and printing them on the screen, parts insertion is possible. After installing machine parts on the machine, you can easily check the installation position of manual parts. Can be installed.

[0007] Silk printing (hereinafter simply referred to as printing) distinguishes manual parts from machine parts. ) The display can be distinguished by double printing with different printing colors, and the display code can be distinguished. Print with a white printing frame, for example, display part symbols with white markings to distinguish them, or By printing the parts mounting position with a border and also by printing the parts mounting hole with a border. can be distinguished.

[0008] Furthermore, by combining at least two of the above-mentioned plurality of printed displays, it is possible to manually feed parts. It can also be differentiated.

[0009] In this way, by differentiating the installation display printing for manual parts and machine parts, Manually inserting parts can be installed more efficiently, and errors and forgetting to insert them manually are prevented. can be stopped.

【Example】

An example of the structure of a printed circuit board according to this invention will be explained based on FIGS. 1 and 2. Ru. Figure 1 is a perspective view showing the printed circuit board and mounting parts, and Figures 2 (A) to (D) are printed tables. FIG.

[0011] In the figure, 1 is a printed circuit board, 2 is a manually inserted capacitor, and 3 is a machine part. 4 is a machine component transistor, 5 is a printed circuit board for capacitor 2. 1 is the mounting hole provided on the top, 6 is the printing of the C1 code on the capacitor 2, 7 is the capacitor Circle mark printed showing the installation position of resistor 2, 8 is R1 of resistor 3 of machine parts Code printing, 9 is machine parts transistor 4 Q1 code display printing, 10 is parts removal. A circle mark is printed to represent connected holes 5, and 11 is displayed with double printing. 12 is the printing of the C1 code with the display code displayed in a print frame, 13 is the capacitor. The C1 code is printed around the mounting position of capacitor 2, and 14 indicates the mounting hole 5 of capacitor 2. This is printing with thicker lines and borders.

0012 The electronic component mounting surface of the printed circuit board 1 is generally marked with easy-to-identify white printing. Mark the display code, such as the REF.No. of the component, the symbol of the R1 resistor, and the symbol of the C1 capacitor. This makes it easier to install parts and replace service parts.

[0013] In the assembly production process of the printed circuit board 1, the first step is to attach it to the printed circuit board 1. Machine parts such as resistor 3 and transistor 4 that are removed are replaced by a parts insertion machine. puter control and install, after installing this machine parts 3,4, the capacitor Attach the manual feed parts in step 2 by hand.

[0014] In this way, after many machine parts 3 and 4 are installed, manual feed part 2 is installed. In order to install the manual component 2, check the silk-printed display code and install the component. can become. The display code for manual part 2 is the same as the display code for machine parts 3 and 4. Because they are displayed separately, it is easier to manually feed parts 2, and it is easier to manually feed parts 2. You can eliminate errors and forgetting to insert your hand.

[0015] The printing of the display code for manual feed part 2 is different from the printing of the display code for machine parts 3 and 4. To differentiate, there are many prints as shown below.

[0016] (Printing example 1) As shown in Figure 1, cover the mounting hole 5 of the capacitor 2 of the manual insertion part. A substantially circular circle mark 7 is provided to indicate the installation position of the capacitor 2, as shown in the figure. In the vicinity of this circle mark 7, there is a designated color C1 code 6 to distinguish it from machine parts 3 and 4. This is what was printed (changed the print color) and displayed.

[0017] (Printing example 2) As shown in Figure 2(A), the printing of capacitor 2, which is a manually inserted component, is Print in a color different from that of manual feed part 2, and make the line width of C1 code 11 thicker. After that, we decided to perform white silk printing on the entire printed circuit board 1 as usual. Therefore, C1 code 11 can be displayed with a double-printed display code, and machine parts It can be distinguished from 3,4 printing.

[0018] (Printing example 3) As shown in Figure 2(B), the C1 code of the manual feed part is printed in white, for example. This white printing frame 12 displays the C1 code in white and inserts it into the manual feed section. The C1 code of the product can be clarified.

[0019] (Printing example 4) As shown in Figure 2(C), the installation position of capacitor 2 of the manual insertion part is Border printing 13 is applied to cover the displayed circle mark 10, and C1 is applied to this border printing 13. The reference numeral 6 can be printed as shown in the figure to distinguish it from the machine parts 3 and 4.

[0020] (Printing example 5) As shown in Figure 2(D), the mounting hole 5 of the capacitor 2 of the manual insertion part is Make the line thicker and apply border printing14 to distinguish it from the display code of machine parts 3 and 4. Can be done.

[0021] Above, printing examples 1 to 5 have been described, but other different types of printing other than those mentioned above have been described. It goes without saying that it is okay to distinguish between the display codes for manual parts 2 and machine parts 3 and 4. There is no. In addition, by combining the above embodiments, it is possible to more clearly define the manual feed part 2 and the machine part. It is also possible to distinguish between 3 and 4 display codes. Furthermore, the above explanation is based on the printed content of manual feed component 2. This was done by changing the appearance of machine parts 3 and 4, but conversely, it is now possible to differentiate them by changing the printing of the markings on machine parts 3 and 4. It is also possible.

[0022]

[Effect of the idea]

As mentioned above, the structure of the printed circuit board according to this invention is such that the mounting position of manual parts is Since it can be easily checked, it is possible to prevent errors in manually inserted parts or forgetting to insert them manually. This has the effect of reducing defects when assembling parts of printed circuit boards.

[0023] In addition, there is no need to refer to assembly specifications during production or check the assembly specifications. It is possible to speed up production, improve productivity of parts assembly, and increase production speed. This also has the effect of reducing man-hours.

[0024] Moreover, it has a simple structure and can be constructed at low cost. It has excellent features such as being easy to use.
