本発明は電子部品の特性値を示すカラーコード表示（以

できるカラーコード検査方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a color code inspection method that can accurately and automatically detect defects in the form of color code displays (hereinafter referred to as color codes) indicating characteristic values of electronic components.

性に問題がある。又全数検査では人手を多く要し電子部
品のコストＦ昇の一因となっている。Conventionally, color code inspections of electronic components have been carried out by visual sampling or 100% inspection. In the case of strip inspection, color code defects caused by temporary fluctuations in the color code printing machine during operation may be overlooked, which poses a reliability problem. In addition, 100% inspection requires a lot of manpower, which is one of the causes of an increase in the cost of electronic parts.

とがのぞまれている。In particular, as electronic components have become smaller in size, it has become increasingly difficult to detect faulty power cables. In addition, with miniaturization, there is a tendency for color code defects to increase, making inspection more important. For this reason, it is desired to detect power code defects reliably and at low cost, especially in small electronic components.

In FIG. 1, 1 is a resistor, and its configuration is as follows. First, a resistive film is formed on a cylindrical ceramic substrate.
-C+Yaffe 2.2 is connected to both ends of the electrode as electrodes. Next, the resistance value is adjusted by trimming, and then the resistive film is painted. Finally, a color code 3 indicating the resistance value, resistance value tolerance, etc. of the L resistor is formed.

選別部１１を備える。In this embodiment, first, approximately 0.3% of a fluorescent agent is added to each color code paint constituting the color code 3 described above. The color code 3 of the resistor formed of the color code paint containing such a fluorescent agent is irradiated with ultraviolet rays 5 from the ultraviolet generator 4. The fluorescent agent in the color code 3 irradiated with ultraviolet rays 5 generates fluorescent waves 6. This fluorescent light wave 6 is received by a fluorescent light wave sensor 7 and the detected amount is sent to a controller 8. In this case, the amount of light of the fluorescent light wave 6 is proportional to the area of the color code 3 irradiated if the irradiation conditions of the ultraviolet ray 5 are constant. Therefore, if a part of the color code 3 is not formed, or if there is an abnormality in the line width of the color code 3, or if there is a deviation from the area of the regular color code 3, the amount of light of the fluorescent light wave 6 will be adjusted accordingly. Also fluctuates. Therefore, the amount detected by the sensor 7 also changes depending on the amount of light of the fluorescent light wave 6. On the other hand, the controller 8 includes a detection amount setting section 9 for setting the detection amount of the sensor obtained from the range in which the color code 3 is considered to be a good product, and a detection amount setting section 9 that sets the detection amount of the sensor obtained from the range in which the color code 3 is considered to be a good product. A calculation section 10 compares and calculates the output detection amounts, and a sorting section 11 performs sorting by determining, through this comparison, those within the detection amount setting range as good products and those outside the detection amount setting range as defective products.

If the above method is used, all the resistors can be detected with high precision, and since there is no need for human visual inspection, labor can be significantly reduced.
