With the maturity of the integrated circuit industry scale, and the promotion and popularization of the application field, more and more Sanxin IC chips emerge on the market.
At present, there are many fake and shoddy products circulating in the market of electronic components and components. Especially, driven by interests, there are a few people who use shoddy products and fake products in the market, which damages the fair market environment, not only infringes the intellectual property rights of original manufacturers, but also endangers the quality of terminal electronic products, and seriously affects the interests of all links in the chain of China's electronic industry. It has brought bad influence to the healthy development of the industry.
There are a variety of ic chips on the market, and sometimes it is difficult to distinguish the difference between various materials, so the identification of IC counterfeit renovation is very important.
Here are some common types of retread
01 disassembly
Used products removed from recycled PCB boards are then refurbished by grinding, coating, retyping, re-tinning, finishing and other processes;
Features: The model has not changed, the surface of the product body has been polished and re-coated, generally the pin will be re-tinned or re-planted ball (depending on the packaging);
02 Counterfeit product
A type of material, after grinding and coating renovation, hit B type of material, this kind of fake products are very terrible, some functions are wrong, can not be used, just packaging;
03 stock
Inventory time is very long, the model is old, the price is not good, the market is not good, and then after polishing, coating, retype, type the New Year
04 Re-tinned
For some old materials or poorly preserved materials, the pins will be oxidized, which will affect loading. After treatment, re-tinning or re-planting, the pins will look more beautiful and easy to load.
05 Defective products of original factory
After the original factory has been tested, part of the products with inconsistent parameters will be eliminated. Some of the materials in this part will be scrapped by the original factory, while some will flow to the market through special channels. Because there are many and miscellaneous batches, someone will re-polish, coat, mark a unified batch, and re-package, so as to facilitate sale!
06 Original mantissa or multiple batches of samples
Because the batches are many and miscellaneous, some original factories will re-polish the coating, make a unified batch, complete packaging, packaging and shipping;
