How's the scrap capacitor business? I wish I could tell you something about it. I heard that the capacitor is full of treasures. I wonder what the capacitor is for?

"Garbage Throwing" in Electronic Components Industry

Status quo: Run a small supermarket for home appliances, live a quiet life and occasionally post on the Internet.

Testimony: the "garbage" industrial chain of Shenzhen electronic components market: trade-in old products for new ones, forge famous brands, smuggle electronic waste, and have chaotic sales. ...

Before exposing the shady business in this industry, I want to ask my friends a question: Do you know where all the components in the discarded electronic products have gone?

This phenomenon may be familiar to everyone: in the streets and alleys of many towns, people push bicycles or tricycles almost every day, and the signs of recycling old electrical appliances are hung on the cars. The recycled products include TV sets, monitors and other electronic products, and the prices are relatively low, ranging from 10 yuan to 100 yuan.

What are these recycled old household appliances used for? In fact, except for some parts that really can't be used, many of them have been taken down, refurbished and resold.

I have been engaged in the electronics industry for many years, and it is no secret that merchants remove the components in waste electronic products and renovate them before selling them. Quite a few electronic factories in China have the habit of using this kind of components, because the cost of using this kind of components is lower than that of buying regular brand-new components by more than 50%. Some manufacturers use this second-hand product in order to reduce costs. For example, in the electronics industry in Shenzhen, which I am familiar with, many manufacturers do just that.

One-stop trade-in

As we all know, Shenzhen is known as the largest electronic component trading center in Asia. The main trading market is in Huaqiang North, the most prosperous area in downtown Shenzhen. Trading markets include SEG Electronic City, Xinya Electronic City, Metropolitan Electronic City and Jiahe Electronic City. Merchants selling electronic components also gathered near Huaqiang North. Other electronic component markets include Shajing Electronic City and Longgang Electronic City, and others can be ignored.

There are many merchants, roasted seeds and nuts merchants, leather bag companies and electronic component dealers in Shenzhen electronic component market.

Small advertisements for purchasing electronic components are posted on the walls or telephone poles in many industrial areas in Shenzhen, which is also a unique urban psoriasis in Shenzhen (although it is also found in other cities, it is the most serious in Shenzhen), and the mystery is very interesting. Someone specializes in buying electronic components stolen by workers in electronic factories. Workers steal electronic components from factories by ants moving. Of course, IC is the most stolen. Of course, resistors and capacitors are too cheap. SMT workshop, PCBA workshop, assembly workshop, maintenance workshop and warehouse may steal valuable IC. Shenzhen y company once lost 2744PCS MI360 chip from the chip testing room. Each piece of MI360 is worth about 25 yuan, and the loss value is 6000. Buyers of electronic components buy back electronic components at extremely low prices, and then process them and sell them as new products.

Dismantling goods and scattering new goods are also very harmful. Dismantling goods means removing valuable electronic components from bought waste circuit boards and repackaging them into new goods for sale. The profit is extremely high. Many companies are happy to do this business, and some customers deliberately buy disassembled goods because disassembling goods can reduce product costs. Large quantities of new goods are mainly second-hand goods that have exceeded the shelf life or have been seriously oxidized. This kind of goods is very common in Shenzhen market, because electronic components also have a life. For example, the electrolytic capacitor of DIP is easy to oxidize, and its storage life is much shorter than that of SMD. For example, the pins of IC are easily oxidized.

Some companies specialize in purchasing electronic components stored in closed factories, and the acquisition cost is extremely low. These companies can renovate or package electronic components and sell them. They often have their own decoration equipment or packaging machinery, which is a one-stop service. You can print your own label or logo, and even make your own plastic packaging board or braid. In addition, the recycled electronic components are packaged into famous brand electronic components, such as Rohm, Motorola, Guo Ju, ST, NS, ATMER and other famous brands. It is easy to be counterfeited, and the price of 0805 (5%) patch resistor packaged in ROHM is doubled. If it is an IC, the profit will be even greater, ranging from several times to dozens of times.

Throwing smuggled goods

Many people who do business in electronic components in Shenzhen are Chaoshan people. Chaoshan people are called Jews in China. Generally, they don't pay attention to children's schooling. Teenagers follow their elders to start businesses, starting with the lowest errands, but they can also be worth millions.

Chaoshan boss can not only fake but also do smuggling business. Electronic components smuggled in from Hong Kong are often several container trucks. Several Chaoshan bosses estimated the quality of electronic components in container cars, and resigned themselves to losing money or making profits, so they chose a container and bought it all. They took these electronic components to the underground processing plant for reprocessing, repackaging, screen printing and LOGO printing, such as photosensitive chip OV7949, and then repackaged them in plastic trays, each with 49 pieces. Once, the serial number of AVX tantalum capacitor was wrong. Authentic AVX starts from the Taj Mahal and is packaged by TJA in underground processing plants. Shenzhen y company likes to use fake tantalum capacitors from Shenzhen s company. The model of this tantalum capacitor is 22UF 6.3V P, and the genuine product price is above 0.25 yuan, while the smuggled product price is 0. 14 yuan. In order to save costs without affecting the quality, Company Y chose this tantalum capacitor, knowing that it was a fake.

I checked some information and found that 80% of the electronic waste generated in the United States is exported in containers and shipped to India, China and Pakistan. Among them, China accounts for 90%. These smuggled electronic wastes basically flowed into some manual workshops along the coast of Guangdong and Fujian, and were illegally dismantled. E-waste from abroad is generally transported to China through Hongkong, Taiwan Province Province and the Philippines, and then flows into the market for sale through some special and secret channels.

There is no accident, only I don't know.

In the business of selling electronic components in Shenzhen, bribery is a well-known thing and a rule. As the boss of Company P said, we should try to get him to eat these purchases without taking kickbacks, even if he pries open his mouth and shoves them in. The return point of resistance and capacitance is usually 3 to 5 points, and IC usually depends on the profit of IC. Usually buyers will ask for kickbacks, and they will not cooperate if the order is less. They get kickbacks even higher than wages. G purchases 3 million electronic components a month, and the rebate is not less than 1.5 million yuan. Salespeople usually take the purchased things to eat, and each meal is not less than 2000 yuan. Generally, they are high-end hotels, and there are also gifts. As for foot washing, massage and sauna, it's small. Once the bribe is successful, the buyer will talk to the merchant and play tricks in the bidding process, and the bidding will become a flower shelf.

Another is to produce fake goods by yourself. There are two small electrolytic capacitors on the market that are fake.

It is possible that what I said is no longer a secret to many people, because it is a hidden rule of the industry, and everyone does it, otherwise how can they make money? There are all kinds of trading methods in this industry, which insiders can't think of, but only outsiders don't know. As an insider, I shouldn't turn my elbow outward, but some words have been kept in my heart for a long time, and it's hard not to say them.
