How does IC chip identify the true and false, and break through the non original camouflage of ATMEL

This time mainly explains the method of ATMEL IC chip to identify the original and non-original. Taking the model AT24C02 as an example, the Xida Electronic Element Procurement Platform teaches you the identification details of the brand from the following points:

 

① (Usually the production date of the plastic disc must be earlier or at the same time as the production date on the label) The production date of the original product label is the 12th week of the year 20, that is, March 2020, and the production date of the plastic disc is also March 20, Almost the same period; the non-original packaging factory date is the 6th week of 20 years, that is, mid-January 2020, and the plastic disc production date is March 2020, which is unreasonable;

 

②After zooming in on the font on the label, the edges of the original authentic fonts are all regular and toothed, especially where there is a curvature; the edges of non-original fonts are uneven in depth;

 

 

③On the plastic disc label, the font size of the original genuine model and the batch number will not be the same, usually the batch number is larger than the model; the font size of the non-original model and the batch number will mostly be printed the same;

 

④ (As mentioned in the previous explanation, the original authentic IC chip straps are mostly recycled materials) ATMEL original authentic straps, every 20 holes will have a complete and hand-engraved "ps 6" recycled material identification; not The original material identification is incomplete and regular;

 

⑤There are requirements for the original and genuine silk screen arrangement, and the batch number on the third line will hardly be filled completely with the first two lines; if it is not original, it will be filled completely;

 

 

⑥There will be two recessed round holes on the back of the original genuine product, which are marked with the place of origin and the code; if it is not the original product, there will be no.
