As an electronic component, the distribution of integrated circuits, our biggest advantage is the details of the flow of products to control, but there are too many need to pay attention to the place ... ...

As an electronic component, the distribution of integrated circuits, the product itself is not developed by our R & D, do not have the pricing of components, product distribution channels we are not the main channel, so we must be very clear their own advantages.

Our advantages are: ① product flow details to control (the original product is responsible for the production but not responsible for circulation, the agent is responsible for circulation but the internal division of labor is too small, the business is too busy, can not be the product of the expertise to the customer's engineers, Quality control, storage, production, commissioning, etc.); ② flexible (can BOM with a single, you can split the sale, you can stock consignment, you can cash account); ③ neutral position (agents usually only recommend their own brand , And shielding out other brands of some technical information, may cause some of the more cost-effective products, can not enter the engineer's vision).

Highly determined vision, the angle to change the concept, and the details determine success or failure.

In the distribution process of components, there are many specific products and product models on the details of the trap. Some customers inquiry, there is no label brand, no model suffix, most of the product is only functional models. Do not know this is not representative of the majority of the situation, usually we received the inquiry will exist in the following details of the trap:

Brand traps: take optocoupler 817, the global production of optocoupler 817 no less than ten brands, theoretically can be replaced with each other, but in the application of strict requirements, you need to go through the engineer's test, after the normal flow into the production The If not and customers confirm that there will be the product can not be used normally hidden.

Function type trap: For example, the function model of optocoupler 817 includes CTR this parameter, each brand will have several levels to subdivision the use of the product. If you ignore this aspect, it is likely to give customers the product is not the other side of the need, and then produce additional costs on the logistics, and even the customer's product problems, bring economic losses.

Suffix Trap: Suffix includes package form, pin size, packaging and so on. For example, the customer has been specified to be the packaging of the patch, but in fact the package has a wide package and narrow feet; pin size is also divided into red solder welding process and solder paste welding process size; There are chip pins marked bit; the most important thing is the iron feet and copper feet of the points. If these problems are not clear, will give the customer's products in the production process to bring great hidden dangers. Product complete model = brand prefix + function model + details of the suffix, the full model of any letter or number of numbers if less one is a trap.

Top mark traps: remember to ship to customers before the SN74LVC4245APWRG4 500, to the customer confirmed the complete model, because there is no original packaging, to the customer where the quality does not accept, because the chip model is LJ245A, insisted to return, and later to Customers to open the PDF document to him to see the goods into the warehouse. In fact, LJ245A is the top of this full model mark. We often encounter some small size of the package, basically have to touch the top mark. Do not pay attention to it, will produce unnecessary trouble, or even cause the order to return. The reason is simple, not every practitioner is professional, not at the beginning to think about looking at the chip PDF document.

Production lot traps: some customer quality will be required within a year and a half of the production of components of the batch number, and some will require the production batch within two years, if the procurement did not ask the supplier's production lot number, then Will face the risk of customer rejection. So that we will catch the logistics freight back and forth, and if the supplier does not agree to replacement, then these products will become our inventory, and even die dead material.

Cracking and testing traps: We all know that the original wafer manufacturing and packaging testing, usually not in one place, and the original wafer manufacturing and packaging testing will usually have a few, but also including the original generation Business. The packaging of the chip or the top mark is usually only sealed. Sometimes the customer will specify the origin of their products to be, these aspects also we should pay attention.

To sum up: the top of the components mark, the production batch number, such as packaging and testing related to the physical and appearance of components factors. This is the details we need to pay attention to. You can post the possible details of the problem, the front to the quotation link, including the product's complete model, packaging model, the number of quotations, brand name, unit price (tax / not tax), functional brief, product packaging and testing and production Batch number, and even the top of the mark to explain, as well as alternative materials to stop the tips, etc., to avoid the details of the product supply in the negligence and legacy. In addition, there are details of the contract trap, such as the contract signed place, account period, logistics. This is no longer elaborated here.
