Many people have encountered the situation of being rejected for small quantities when asking about SMT, and most of the reasons given for the rejection are "small quantities are not cost-effective" and " High  start-up losses". What are the so-called losses? Before SMT processing, you need to do the same preliminary work as when you receive a large order, such as SMT machine programming, PCB positioning, start the first piece of confirmation of this type. In the case of a small amount, the so-called loss, more is the loss of time. Because in the same time, the production efficiency of SMT with large processing volume is higher, so as not to waste time on the preliminary work after a morning or a day of production. And in the machine in and out of the time, so we prefer to receive the kind of area is not very large, but the patch point is very concentrated, so that both high efficiency, but also greatly save a variety of labor costs, machine losses, etc.   To quote

In the process of purchasing electronic components, the most worrying thing for buyers is not the price, but the quality of the product. There are a variety of IC chips on the market, of all kinds, and without paying attention to the distinction, it is sometimes difficult to see the difference between various materials, whether it is true or false, new or refurbished. The following is a compilation of some methods to identify genuine and fake chips, for your reference. Common chip counterfeiting methods Material A counterfeit material A Original manufacturer's tailor loose material: the original packaging has been disassembled or is no longer available, but product functionality and yield may be lower due to storage time or handling process, etc. Original manufacturer scrap or defective products: mainly products that have not passed factory inspection by the original manufacturer, such as scrap products after reliability testing, poor packaging quality, bad test products, etc. Orig
