What are the requirements for temperature and humidity in the SMT patch processing plant?

The SMT patch processing is easy to understand: the capacitors or resistors on the electronic products are attached with a special machine and welded to make them stronger and not easy to fall to the ground. For example, the high-tech products and mobile phones that we often use nowadays, the internal motherboards are densely packed with tiny capacitor resistors. These capacitor resistors are printed by SMT chip processing technology and processed by high-tech patch. The capacitance of the capacitor is much faster than that of the manual manual patch, and it is not easy to make mistakes.

SMT is the abbreviation of Surface Mounted Technology, which is a popular processing technology in China's electronics industry. Now that SMT chip processing is a high-tech product, I think it has high requirements for the processing shop. What kind of workshops are needed? Let's take a look.

SMT chip processing has certain requirements on the environment requirements, humidity and temperature. In order to ensure the quality of electronic components, the number of processing can be completed in advance, and the following requirements are imposed on the working environment:

The first is the temperature requirement. The best temperature in the factory is 23±3°C, which can't exceed the limit temperature of 15~35°C.

Secondly, the humidity requirement, the humidity of the SMT patch processing workshop has a great influence on the quality of the product. The greater the environmental humidity, the more easily the electronic components are affected by the moisture, the conductive performance is affected, the welding is not smooth, the humidity is too low, the workshop The air inside is easy to dry, and it is easy to generate static electricity. Therefore, when entering the SMT chip processing workshop, the processing personnel also need to wear anti-static clothing. Under normal circumstances, the workshop is required to maintain a constant humidity of around 45% to 70% RH.

In addition, it is the requirement of cleanliness. If there is no smell or dust in the workshop, keep the internal clean and non-corrosive materials, they will seriously affect the reliability of the capacitor resistance, and will increase the failure of the chip processing equipment. Maintenance rate, reducing production progress. The best cleanliness in the workshop is best around 100,000 (BGJ73-84).

Finally, the stability requirements of the power supply, in order to avoid equipment failure during processing, affecting the processing quality and progress, it is necessary to add a voltage regulator to the power supply to ensure the stability of the power supply.

The above is the industry consultation provided by smt patch processing factory Shenzhen Pengzexiang Technology Co., Ltd., I hope to help you! Please contact us if necessary: http://www.oem-pcb.com pcb@sunsoartech.com
