First of all, we need to understand the types of electronic components that appear in the market.
First、Definition of original packaging: Products with original packaging.
Second、The definition of original packaging: the original packaging has been opened or no original packaging, but it is the original factory, and now many goods in the electronic market are such original packaging. The reason is that suppliers usually break up some of the surplus materials after the original packaging is sold at a high price in order to meet the demand of customers'scattered consumption. Shenzhen also has some suppliers who bring them from Hong Kong to the mainland market in batches in order to evade tariffs. In addition, there are tailings purchased by distributors from OEM customers or Excess inventory.
Third、New products in bulk can be divided into the following situations according to the market conditions:
1. Dispersion in the true sense (i.e. no original packaged goods)
2. Disseminating new products (i.e. defective products) with sub-filling is mainly products that have not passed the ex-factory inspection. They can only meet the general requirements in terms of performance and have the possibility of failure. However, because they are processed products, the price has great advantages, mainly obtained from some agents and distributors, and the batch numbers are confused.
3. Fake renovation (i.e. refurbished goods)
Fourth、 renovation: In the true sense, one kind of renovation goods is used goods renovation, but there are also quite a number of renovation goods on the market are fake.
Fifth、Junk: commonly known as disassembly parts, that is, from the product has been used, through hot air or fried way from the PCB. Some businessmen can simply test the used goods or dismantled parts, some can continue to use directly, and some need to renovate the process before use, there is a certain failure rate on the computer.
Discrimination skills:
1. For the original packaging materials of the original factory, if they are ordered from the original factory or the authorized agents, there is no need to worry. If they are ordered from the dealers, we need to pay attention to them. At present, there are a lot of fake original passive devices, such as resistance and tolerance, which use the small brands of national products to make logos to pretend to be imported brands, and Some IC uses refurbished material repacking to pretend to be new original. It is difficult to identify the appearance of domestic brand pretending to be imported original. It is only through comparison that there are still some differences in outer boxes, labels and packaging.
2. To distinguish between original or refurbished goods, we need to know the process of dealing with used goods: mainly through the re-processing of old films, such as grinding, washing, pulling, plating, jointing, grinding, typing and so on. Processing the appearance of the chip makes the chip look more beautiful, even to the extent of falsehood. Now the handling of second-hand goods is also an industrial chain, even including vacuum bags, labels, foam, carton and other processes. How to distinguish new goods from refurbished ones?
