What should I pay attention to when purchasing components online?

Only the best procurement. Quality***.

Electronic components are generally divided into domestic and imported components, the normal domestic procurement process: looking for manufacturers - sampling - price comparison (bargaining) - order - follow-up - feeding - exception handling - reconciliation, etc., while foreign imports need to find the original manufacturer or distributor through the component brand, and then choose the most favorable communication method to contact ** - sampling, etc.

However, whether it is domestic procurement or overseas procurement, it is necessary to pay attention to these details in the procurement process of components

1) Familiar with the appearance, model, performance and parameters of components. (2) Familiar with the market**. (3) Pay attention to MOQ and MPQ.

4) Review the supply qualification. (5) Determine the delivery date and transaction conditions. (6) Clarify the mode of transportation and delivery.

You can learn about Lianchuangjie Technology, they are a first-class distributor focusing on value-added services for semiconductor components, with BOM whole order "one-stop" complete set of ** chain services, and the complete set rate of materials is up to 90%; In addition, it also provides flexible resale of more than 30 OEM and EMS factories commonly used inventory, which is reassuring.

Observe the appearance: Check the components for obvious physical damage or oxidation, such as cracks, scratches, discoloration, etc. Intact components typically have a smooth appearance, no visible damage or corrosion, and meet specifications.

Verify the mark: Check whether the identification of the component is clear and legible and meets the requirements of the product specification. Some electronic components may be tampered with with their identification codes, so special attention is required.

Measurement parameters: Use test equipment to verify the actual parameters of the component, such as resistance, capacitance, inductance, etc. This helps to verify that the component meets the specifications and to check for damage.

Further validation: If possible, the component can be further tested, such as using an oscilloscope, multimeter, etc. to verify its functionality. This can better ensure that the quality and performance of the components meet specifications.

In summary, upon receipt of a component, a visual inspection should be carried out, followed by basic testing and verification to ensure that the quality and performance of the component meets specifications. If the inspection finds any quality problems, you should give feedback to the supplier in time and seek solutions.

Look at you still delete my post!

It is recommended to go to the international electronic business to understand the best and industry insiders, and the procurement can be on Ali.

Like me, I don't want to look for it on the Internet, because a lot of ** is as long as you pay money, they let you advertise, basically like this, so I hate this very much, or you ask, those who have been deceived, are they all played on the Internet, I don't know it, many companies basically don't exist, exaggerated.

Like my current suppliers, are introduced by friends and the like, I think this is a little more reassuring, after all, friends will not harm us, I think so, at least ** and so on, I can only say that you get what you pay for, now the market is very chaotic, and there are many old and renovated ones, and we can't keep up with this kind of knowledge.

I remember that our current supplier, that is, a company called Tianyi Electronics in Shenzhen, said a word, I think it is very reasonable, he said that our ** dare not say that it is very cheap, very advantageous, but I can guarantee that our goods are original**, will not be confused.

I think it makes sense, if you buy some cheap ones and wait until the machines are all burned out, so what? Pay for one's whistle.

You can go to IC to find the best business, shop around, and quality is very important.

The procurement of electronic components can be done through one-stop procurement, which can save procurement time and cost. One-stop procurement refers to the centralized procurement of various electronic components on a certain platform, such as e-commerce platforms, component distributors, etc. When choosing a one-stop procurement platform for IC shopping, you need to pay attention to the following aspects:

Platform credibility: Choosing a platform with credibility and reputation can be determined by looking at the platform's user reviews, ratings, company qualifications and other information.

Product quality: Choose a platform with quality assurance, you can view the specifications, models, production dates, origins and other information of components to ensure product quality.

Product**: Compare the products of different platforms**, and choose the most reasonable and cost-effective platform.

After-sales service: If you choose a platform with after-sales service guarantee, you can check the platform's after-sales service policy, customer complaint handling mechanism, etc., to ensure the quality of after-sales service.

When buying electronic components, you need to make sure that you are buying authentic products. You can check the appearance, weight, feel and other characteristics of the components by checking the identification, labels, packaging, etc. of the components to ensure that you are buying authentic and credible products. In addition, it is necessary to choose a reputable supplier and understand the quality control process and after-sales service policy of the supplier to ensure product quality and after-sales service.

Now there are a lot of wrong electronic components transactions, and some of them have good reputation and qualifications, and they are large-scale transactions.

Of course, no matter which platform you choose, here are a few things to keep in mind:

First, the industry's reputation.

In fact, at the beginning of the procurement of components is still relatively unfamiliar, you can look at the evaluation of friends who have purchased to pick out a few good reputation, after all, if the reputation is good, it is also good to prove the quality of components, delivery, and complete types.

Second, the scale of the enterprise.

When choosing electronic components, it must depend on the scale and strength of the company, because the company is strong, and it will also save procurement costs when doing activities. Therefore, when choosing electronic components, we must pay attention to the scale of the company's operation.

3. Professional services.

Due to the rapid development of the information society, more and more industries are booming, buying things has become a simple and fast thing, and online electronic component procurement platforms have sprung up in an endless stream. However, the procurement platform is uneven, and it is easy to be deceived, and the after-sales service is not responsible and there is no guarantee.

Fourth, whether it is spot inventory.

In the era of shortage of IC chips, many ** are now out of stock, and they may only be shipped in a month or months. So, before purchasing, it's important to check if it's in stock.

Although the selection of components is not a difficult task, it is also very troublesome, and if you are not careful, if you purchase "defective" or "fake", it will be very devastating.

1. First of all, pay attention to whether there are traces of polishing on the surface of the chip.

2. See if the printing is blurry and the depth is not.

1. The position is incorrect, easy to erase or too conspicuous.

3. Look at the pins, where the light is as bright"New"The tinned pins must be refurbished, and the vast majority of the pins of the genuine IC should be so-called"Silver powder feet"

4. Look at the production date of the device and the label of the packaging factory, the label of the genuine goods, including the number on the bottom surface of the chip, should be consistent and the production time should be consistent with the device quality.

5. Measure the thickness of the device and look at the edge of the device, because the plastic device must be molded after injection molding"Demoulding"Therefore, the edge angle of the device is circular (R angle), but the size is not large, and it is easy to grind the fillet into a right angle during grinding processing, so once the front edge of the device is a right angle, it can be judged as a grinding product.
