  采购电子元器件,买原装是每个客户希望的事,买到非原装是每个客户都不希望发生的事,如何避免买到非原装IC就成为采购关心的事儿, 希达原装IC现货自营 平台,以型号LM2596SX-5.0开关稳压器为例,整理“辨别元器件真伪”干货分享(胶盘颜色可忽略,不做为辨别依据)。

To purchase electronic components and parts with original packaging is what every customer hopes, and to purchase non original packaging is what every customer does not want to happen. How to avoid purchasing non original IC has become a concern of the procurement. XiDA original IC spot self operated platform, taking LM2596SX-5.0 switch voltage stabilizer as an example, sorts out "identifying the authenticity of components" dry goods sharing (the color of the rubber plate can be ignored, and is not used as a basis for identification).

一、盘和带子:

  ①盘装,通常原装品胶盘材质较细腻显光滑,非原装品胶盘显粗糙;原装刻字工艺成熟,盘表面所刻字可做到字体线条中间稍微凹陷这样的精工细作,非原装品则做不到;

1. Plates and straps:

①Plate packaging, usually the original authentic plastic plate is more delicate and smooth, and the non-original plastic plate is rough; the original lettering technology is mature, and the lettering on the plate surface can be finely crafted such as the middle of the font line is slightly recessed, and the non-original product is made Less than

 

②标签,标签代表产品原厂凭证,原装品标签品牌LOGO喷墨均匀(重点),非原装反之;

②Label, the label represents the original certificate of the product, the original authentic label brand LOGO inkjet uniformly (emphasis), non-original vice versa;

 

  原装序列号数字重叠部分排列错开,非原装序列号则排列对齐;

The overlapping parts of the original serial numbers are staggered, and the non-original serial numbers are aligned;

 

  ③带子,原装品带子压角谨慎,保护膜锁边贴合带子,非原装保护膜与带子边缘分开;

③Straps, the original genuine straps should be cautiously pressed, the protective film is locked to the straps, and the non-original protective film is separated from the edge of the strap;

 

  通常原装品链带多采用可回收塑料材质,背面小方盒间隔或不间隔会有回收标志,非原装则无;

Usually the original genuine chain belt is mostly made of recyclable plastic material, and there will be a recycling mark on the back of the small box with or without interval, and there is no if it is not original;

 

二、产品外观,放大看细节

  ④丝印,原装品LOGO打印无误且清晰(重点),线条流畅均匀,边缘清晰无杂质,用手指擦拭过后无变化,非原装丝印字体线条处坑洼似有腐蚀,用手指擦拭过后指尖或会余留残渣;

2. Product appearance, zoom in to see the details

④Silk printing, the original genuine LOGO printing is correct and clear (emphasis), the lines are smooth and uniform, the edges are clear and there is no impurities, and there is no change after wiping with your fingers. Remaining residue;

 

  ⑤定位孔,无法辨别安装方向的IC均有定位孔,孔内或有字母或无。原装品定位孔棱角分明,弧度显深,孔内所刻字母清晰,(重点)每片芯片定位孔大小统一;非原装定位孔弧度较浅,反光比原装要强,孔内所刻字母显模糊,会出现同盘货中定位孔大小不一情况;

⑤Positioning holes. ICs whose installation direction cannot be distinguished all have positioning holes, and there may be letters or no letters in the holes. The original authentic positioning hole has sharp edges and corners, the arc is deep, the letters engraved in the hole are clear, (key) the size of the positioning hole of each chip is uniform; the non-original positioning hole has a shallower arc, the reflection is stronger than the original, and the letters engraved in the hole are blurred. There may be different sizes of positioning holes in the same inventory;

 

  ⑥管脚,原装品会稍显暗淡,非原装可能经过重新打磨会更显锃亮,且坚固度使用寿命也必然会大打折扣,此处需细心、眼力超群与经验积累,方可辨别;

⑥ The pin, the original product will be slightly dim, and the non-original product may be brighter after re-polishing, and the durability and service life will inevitably be greatly reduced. Here you need to be careful, excellent insight and experience accumulation, before you can distinguish;

 

 

  目前市场流通的电子元器件,原装与非原装产品区别基本从前几点可分辨出,其中非原装可能是半成品,亦或是翻新品,相信都不会是您的选择,因此就需要大家多细心观察和学习分辨之法,小编以上所说虽然不能原搬照抄辨别每一种元器件,却是以“细工出精品”的原理为大家指出重要识别之处,“灵活运用,举一反三”方是正理。

The difference between the original and non original electronic components in the current market can be basically distinguished from the previous points. It is believed that non original electronic components may be semi-finished products or refurbished products, which will not be your choice. Therefore, you need to carefully observe and learn how to distinguish. Although the above statement can not be copied to identify each component, it is based on the principle of "fine workmanship makes fine products" to point out the important identification points for everyone, "Flexible use, draw inferences from one instance" is the right way.
