As a distributor of electronic components and integrated circuits, our biggest advantage is to control the details of product circulation. However, there are too many places to pay attention to
As the distribution of electronic components and integrated circuits, the product itself is not developed and produced by us, and we do not have the pricing power of components. We are not the main channel for product circulation, so we should be very clear about our own advantages.
Our advantage lies in: ① controlling the details of product circulation (the original factory is responsible for product production but not circulation, and the agent is responsible for circulation, but the internal division of labor is too fine and the business is too busy to transmit the professional knowledge of components to everyone such as customer engineers, procurement, quality inspection, storage, production and commissioning); ② Flexible (BOM allocation, split sales, inventory consignment and spot accounting period are allowed); ③ Neutral position (agents usually only recommend their own brands and block some technical information of other brands, which may cause some products with higher cost performance and can not enter the vision of Engineers).
Height determines vision, angle changes concept, and detail determines success or failure.
In the process of component distribution, there are many detailed traps on specific products and product models. When some customers inquire, they do not mark the brand or model suffix. Most of them are just the functional model of the product. I don't know if this represents most situations. Usually, when we receive an inquiry, we will have the following detailed traps:
Brand trap: take optocoupler 817 for example. There are no fewer than ten brands producing optocoupler 817 in the world. Theoretically, they can be replaced with each other. However, when the application requirements are strict, they need to be tested by engineers before they can normally flow into mass production. If it is not clearly confirmed with the customer, there will be hidden dangers that the product cannot be used normally.
Functional model: for example, the functional model of optocoupler 817 includes CTR, and each brand will have several levels to subdivide the purpose of the product. If this aspect is ignored, it is likely that the products given to customers are not what the other party needs, resulting in additional logistics costs, or even problems with customers' products, resulting in economic losses.
Suffix trap: suffix includes packaging form, pin size, packaging method, etc. For example, the customer has indicated that the package of the patch is required, but in fact, the package of the patch has two types: wide foot and narrow foot; Pin size is also divided into red glue welding process and solder paste welding process; In terms of packaging method, there is also the marking position of chip pins; The most important thing is that there are iron feet and copper feet. If these problems are not confirmed clearly, they will bring great hidden dangers to customers' products in the production process. Product complete model = brand prefix, function model detail suffix. If any letter or number on the complete model is less than one digit, it is a trap.
Top mark trap: I remember that I shipped sn74lvc4245apwrg4 500 pieces to the customer and confirmed the complete model to the customer. Because there was no original packaging, it was not acceptable to go to the customer for quality inspection. The reason was that the model on the chip was lj245a and insisted on returning the goods. Later, I went to the customer to open the PDF file for him to see before I handled the warehousing of the goods. In fact, lj245a is the top mark of this complete model. We often encounter some small packages, which basically touch the top mark. If you don't pay attention, it will cause unnecessary trouble and even cause order return. The reason is very simple. Not every practitioner is professional and will not think of viewing the PDF document of the chip at the beginning.
Production batch number trap: some customers will require the production batch number of components within one and a half years, and some will require the production batch number within two years. If the supplier's production batch number is not asked clearly during procurement, they will face the risk of customer rejection. In this way, we will get back and forth logistics freight. If the supplier does not agree to exchange, these products will become our inventory or even dead materials.
The trap of packaging and testing sites: we all know that the original wafer manufacturing sites and packaging and testing sites are usually not in the same place, and there are usually several original wafer manufacturing sites and packaging and testing sites, including the OEM of the original factory. The package or top mark of the chip is usually only sealed. Sometimes customers will specify the origin of their products, which we should pay attention to.
To sum up: the top marking of components, production batch number, sealing and measuring ground and other factors related to the physical and appearance of components. These are the details we need to pay attention to. The details that may occur in the later stage can be advanced to the quotation link, including the complete product model, packaging model, quotation quantity, brand name, unit price (tax included / not tax), function description, product sealing and testing place, production batch number, even the explanation of the top mark, as well as the substitution prompt of discontinued materials, etc, Avoid negligence and leftover of details in product supply. In addition, there are detailed traps in the contract, such as contract signing place, accounting period and logistics. I won't elaborate here.
