China Topscom posted latest news in May of 2020.Electronic contract manufacturing service (EMS,Electronic Manufacturing Services), also known as ECM (Electronic Contract Manufacturing), is also translated into professional electronic contract manufacturing service. Compared with the traditional OEM or ODM services, which only provide product design and contract production, EMS manufacturers provide knowledge and management services, such as material management, logistics transportation, and even product maintenance services.
 
Now all kinds of electronic products, especially notebook computers, mobile phones and other products, no matter what the brand is, many are hired professional electronic contract service providers to contract production, famous brands sometimes only provide brand, design, monitoring, technical support. So it can be said that these EMS suppliers are the behind-the-scenes heroes of the best-selling products.
 
China's EMS enterprises and SMT (surface mount) industry can be said to have grown from scratch, from small to large. The development of enterprises reflects the changes of industry. After more than 10 years of development, China's local EMS enterprises have formed a certain scale, which has not only made a great contribution to the development of China's electronic industry, but also led to the development of upstream and downstream industries, especially the upstream equipment and materials industry and downstream terminal consumer products.
