SMT processing is a common component production method in the high-tech industry. Common brands such as Apple, Samsung, Huawei, Xiaomi, BYD, etc. are all using SMT processing methods to produce some parts to varying degrees. This is mainly due to the extremely strict pursuit of the environment and processing details in the production workshop during the processing of this technology.

As is well known, SMT technology is one of the important components of high-tech products. So why do even big brands choose to outsource instead of building their own production lines. This issue involves several key reasons.

It is different from other extensive products. SMT (Surface Mounting Technology) is a surface mounting technology for circuit boards. The processing includes solder paste printing, solder paste inspection, mounting, reflow soldering, AOI optical inspection, visual inspection, and maintenance. The workshop environment and conditions have a significant impact on the qualification rate during the production process.

Firstly, the temperature in the workshop must be controlled between 16 ℃ and 28 ℃, with a humidity requirement of 40% to 70% RH. The temperature in the workshop is monitored by a dedicated person every morning, noon, and evening.

Secondly, the desktop in contact with the materials must be kept clean at all times, and the materials must not collide or fall during transportation.

Thirdly, there are also requirements for staff to wear anti-static clothing, hats, and gloves when entering the workshop.

With the development of integrated circuits, every small circuit board has been given an immeasurable responsibility. The requirements mentioned above are only a part of the main operational specifications for SMT processing workshops, and there are more personalized demands based on different types of products. It can be seen that building a qualified production line requires a high level of funding, a management team with relevant skills, and operators. The sustainable development strategy of outsourcing processing to achieve resource sharing is one of the important reasons why it has become an indispensable link in high-tech blockchain.
