How to identify counterfeit electronic components?

There are so many fakes of components, and some fake components can be simply identified from the label.

Case Study

Today we found several groups of true and false controls to share how to distinguish the true and false components from the label. We can examine a label from four dimensions, 1: Font 2: Seal 3: Logo 4: Line.

Case 1:

• In fact, even without detailed analysis and comparison of these two labels, you can feel some differences at a glance. First of all,

• Differences in fonts. The font of the fake label is still somewhat different from the real label. In the picture, the words LOT DTE look obviously different.

• Differences in seals: The seal on the real label is larger and the spacing of the fonts is wider. The origin of LEOHAN PAOENIX in the fake label cannot be found. The LESHAN PHOENIX on the real label is the name of LESHAN PHOENIX Leshan Phoenix Semiconductor Co., Ltd. and is affiliated with it. ON Semiconductor Division

• The different PB lead-free logo on the logo is really bigger compared to the fake one of E3, and the border lines of E3 are different. The lines of the E logo on the side are fake and thinner, and the font of ON The fake one has larger spacing, the real one has smaller spacing, and the font is.

• The border range is fake larger, but really smaller, and the arrangement of the characters is more compact. 

Case 2:

• Font The fonts of these two labels look quite close, but a closer look reveals the problem. The font of the HF fake label is obviously thinner, and the font of MS LEVEL in the side section is also overall thinner.

• Seal: LECHAN PAOENIX in the fake label should actually be: LESHAN PHOENIX Leshan-Phoenix Semiconductor Co., Ltd. The company name on the fake label is obviously misspelled.

• The two circles of the logo PB E3 for environmental protection and grade are really smaller and more static. The difference between the logo next to the E is actually quite big. At a glance, you can tell that the lines are really thicker, and the E is darker and smaller. , the ON logo really has a thicker font.

• Lines. The lines on the real label are also thinner and wider.

Case 3:

• Font: This kind of label, contrary to the previous two groups, is that the font of the real label is obviously thinner, so this is really not certain. The template of this label is very.

• The seal of the real label is slightly thicker in terms of lines and fonts.

• Logo and this line, whether it is the logo or the line on the side, the label appears to be thinner.

The challenge of distinguishing authentic and fake components from labels

Label comparison to identify authenticity faces two major challenges: 

•  A large amount of original and authentic label data is required for comparison, and many people do not have complete label sample data. Especially for end buyers, and the differences in labels from different periods and origins also increase the difficulty.

•   There is a race between those who make authentic products and those who make fake products. Those who make authentic products are always thinking of ways to identify fake labels, while those who make fake labels are always thinking of ways to make fake labels more authentic. The updating and iteration of counterfeiting technology It is also relatively fast. As time goes by, the identification method of some false tags will become invalid.
