Teach everyone to sign a rework product.

We usually visit the market when we can see some products agents showcase a lot of hot products, in addition to the production for display, there is a use for consumers to come to understand the use of products, and even the agents of the technician used to do the test machine platform, that is, samples or exhibits; So what will the agent do once these products have finished their use? It is understood that in addition to a very small number of manufacturers will be recycled as spare parts, most of them need to dispose of the agents themselves, so naturally through the market to sell to the hands of consumers, the uninformed consumers to deceive, in order to avoid users buy repair products, Here for you to talk about the repair of computer accessories a few simple identification methods:

PS/2 mouth wear. As the interface is generally relatively tight, keyboard mouse more than a few times, there will be obvious wear phenomenon, and this wear in addition to the replacement interface, is not repairable, so it is easy to see out.

I/O interface oxidation. If the repair board to use a longer time, I/O interface should be oxidized phenomenon, although you can use some rust remover to remove it, but it is inevitable to leave some clues, as long as careful observation, you should be able to see. This method is also useful for the identification of metal interface devices such as graphics cards.

Screw hole wear. In the installation process, the motherboard screw hole is very vulnerable to wear, even some careful technician will be in the screw hole with a layer of gasket, but the back of the screw hole is the same as the same phenomenon, although only a little, but can be distinguished.

Gold finger wear and oxidation. Memory or graphics cards, such as through the gold fingers connected to the motherboard equipment, gold fingers after the plug or long-term use, will be subjected to varying degrees of wear or oxidation, if not a layer and simply the use of alcohol and other chemical agents to renovate, still leave the plug or the traces of oxidation, good eye, not difficult to distinguish. However, such as Kingmax and Kingston and other brands in the factory before the need to undergo testing, so will leave the traces of the plug, for such products, we can from the degree of wear to judge, or choose to call security phone verification.

Smell the chemical smell of the board card. The new board will have to go through the washing plate before leaving the factory. The process is generally through the use of chemical solvents to wash away parts of the welding, such as solder and other debris, in order to avoid the motherboard short-circuit and so on. The new board usually has the chemical odor of the detergent residue in the wash plate, it is easy to smell with the nose. and repair board repaired, generally will not experience the process of washing the plate, so under normal circumstances will not have that smell, users in the identification of rework board, may wish to refer to this method.

Note the enclosure of the IDE device. The optical drive and the hard drive generally after the repair will wear the shell to repair and again color, so, the general wear after repair, non-professional Professional is not easy to distinguish. For the optical drive, we can open the tray to see whether the upper and lower sides have been contaminated or there is no dust. And the hard drive after repair, generally not easy to see, in addition to the serial number of manufacturers to distinguish the method, we can only pay attention to the hard disk metal shell has no obvious scratches for simple resolution.

Check the serial number. Most brand-name products will be on the box, warranty card and the motherboard affixed serial number. Agents do not have to rework the box together with the board back to the factory, so, if the manufacturer's own tricks, repair the motherboard and generally difficult with the box or the warranty card on the serial number on the number! This is the key to the identification of rework, please remember this point, the purchase of computer accessories encountered above the case of serial number, Please be sure to ask the merchant to give replacement or return!
