OEM is a brand producer who does not directly produce products. They use their key core technology to design and develop new products, control their own sales channels, and entrust other assembly and SMT chip processing manufacturers of similar products to produce processing tasks through contract ordering. The characteristic of OEM is that only production is inside, technology is outside, capital is outside, and the market is outside. After production is completed, purchase the ordered products at a low price and label them with your own brand trademark. This collaborative method of entrusting others to produce is abbreviated as OEM. The manufacturer who undertakes processing tasks is called OEM manufacturer, and the products they produce are called OEM products. OEM production is also known as fixed point production or OEM production
