For many years, the electronic market has been plagued by a mix of good and bad, with substandard products being used as substitutes and fake products being used interchangeably. Many manufacturers have been deeply affected by this phenomenon. So, how can we distinguish the authenticity of a three terminal switching power supply chip? There are generally three types of fake chips: one is dismantled, one is refurbished, and another is not QC released. So how to distinguish it?
When disassembling, there are usually traces of welding, without signs of oxidation, scratches, and inconsistent batch numbers. This type of chip, due to years of use and severe aging, combined with some already oxidized chips, is prone to false soldering, which can bring unpredictable hidden dangers to the equipment. Refurbished ones, like dismantled ones, have a significantly shortened service life, and some may even be damaged and unable to function properly. The harm is the same as the first type. Refurbished chips are usually polished and re typed, which are beautifully made and have a consistent batch number. However, the polished feet are smaller and very smooth, and the clarity of the characters is different from the original ones. A comparison reveals this. As for those that have not undergone QC, it is difficult to identify and can only be distinguished through functional testing. Those that have not undergone QC have a lower pass rate. If the pass rate of the test is lower than normal, it is basically called loose new.
The appearance of counterfeit goods is very good now, and it is difficult to distinguish them. It is recommended to purchase from a legitimate agent or distributor, so that the product quality will be more guaranteed. Dongguan Zhongming Electronic Original Imported Chip, with guaranteed quality and reasonable price, is your good choice.
