Where do you usually buy chips or components? [Copy link]

 

 

Where do you usually buy chips or components? I found that Taobao is too sick now, the prices are all over the place, and every product with the actual price is basically not shipped once you bid, or they will tell you that the price has increased. If you go to a certain Chuang mall to buy these, the price is ridiculously expensive, several times more expensive. Although I know their quality is more guaranteed, it is still too expensive.

You can't buy the scarce ones on Taobao, not only are they expensive but they are also prone to quality problems. Now the TI official mall is quite cheap. For other small quantities, you can ask agents or manufacturers for samples. The mousers that are hard to get are relatively cheaper, or you can look in ickey.

There are skills to online shopping for components. You must be able to judge the qualifications and products of the seller. Given that the legal management of online shopping in China is seriously inadequate, you must not simply look at the interface and place an order. You must contact the seller to understand and confirm the price and products before placing an order. There is a prerequisite for my online shopping of components. It must be a Huaqiangbei seller with an actual business site. For the first purchase of goods above a certain amount, I will personally inspect the goods and pick them up, trade on the spot, and negotiate future purchases.

Of course, my method is probably not suitable for most DIYers who have a small demand for components but a wide variety of varieties, but it can be used as a reference. For DIYers who have never been involved in productive bulk purchases, they can either accept high prices to buy reliable components from some large online shopping malls, or simply buy second-hand disassembled parts. I used to mail-order disassembled parts when I was a student. At that time, I couldn't communicate with the sellers and had to rely on luck, but recognizing the seller's brand was still effective. I still remember mail-order sellers such as Shenzhen Xixiang Zhenhua Electronics Factory, Zengcheng Zhengguo Radio Factory, and Xiaoshan Louta Transistor Factory...

If it is a large company and does not need too many products, you can ask the agent for samples.

The platform is indeed more expensive than the average one. It is also an option in case of emergency, and the information provided is very complete.

Another feature is fast delivery, almost no holidays

When looking for foreign or local component suppliers, large-scale purchases for batch production, and huge payments, a stamped quotation must be made. The quotation must include company information, and then a formal purchase contract must be signed. The purchase contract must finalize matters such as advance payment, final payment, and after-sales service.

Of course, this is a business matter.

If you are purchasing personally, it is best to sign a contract. When signing a contract, you need to provide the seller's company qualifications, tax number, etc. You need to examine the other party's company in detail, which requires your own judgment.

Things from Taobao, cheap, cheap, out-of-print chips, repair options

It should be possible on Tmall. Generally, the platform review for opening a store on Tmall is quite strict. In the Internet age, formal platforms should be trustworthy.

In the Midwest, local e-commerce suppliers generally have higher prices.

We always ask suppliers for samples, and then compare prices after the products are ready.

OK, thank you. I bought it for myself, not in large quantities. Usually I buy a few hundred or a few thousand tubes or something like that.

The quantity that is neither too big nor too small is the most suitable for online shopping, as I said before. Note that the quantity here does not refer to the number of components, but the total price. Generally, orders of several thousand or tens of thousands are considered "neither too big nor too small".

Generally speaking, it is more reliable to buy from regular channels. There are too many chaotic channels out there. You can't trust it even if you buy it back. We have many customers who bought our OSRAM LEDs, and many of them suffered losses in the end. Some of them were so wrong that the polarity was reversed.

The price through regular channels is definitely still expensive. Taobao is cheap but risky. Generally speaking, it depends on the demand. If it is a common model on the street, there should be no problem on Taobao. However, if you use Ai Zai product or the model is hard to find, you should still go through regular channels, such as Mouser, Arrow, and Digi-Key.
