From the perspective of the original AD chip, the IC identification method is uninterrupted

In this issue, we will share chip identification methods. This time, we will learn about AD chip. Taking ADM3202ARNZ-REEL as an example, we can distinguish it from the following points:

 

①The background color of the precautions label on the original box is light yellow, the first icon is particularly obvious for each finger, and the arrow of the second icon is not similar to the circle; the background color of the precaution label on the non-original box is orange, and the line of the finger icon is not clear, The circle and the arrow icon are connected;

 

②The middle triangle of the AD logo on the original box is a little to the left, and the lower left corner of the letter A is obviously forward; the AD LOGO triangle of the non-original box is closer to the right, and the letter D is closer to the front;

③There are 4 barcodes on the left side of the original plastic disc label and a square QR code on the upper right corner; 5 barcodes on the left side of the non-original plastic disc label, and the QR code on the upper right corner is incomplete;

 

④The pressure line of the original belt protective film is intact, and there is no obvious reflective effect; the pressure line of the non-original belt protective film is uneven, and the reflection is strong;

⑤The original chip has a clear silk screen, the third line of font is consistent with the AD LOGO vertically, and the origin and number are also marked on the back, and the chip pin size is uniform; the non-original third line of font is behind the vertical line of the LOGO, and the back of the font does not indicate the origin and Number, pay special attention to the fact that there are many fake pins that are relatively slender.
