As an important part of the smt production line, Mirae chip mounter is also a precise and complex smt equipment. It has certain requirements for the working environment. A good working environment can reduce the failure rate of the slider and shorten the service life of the slider.

Mirae chip mounter

   One, room temperature

   It is usually good to place Mirae chip mounter and solder paste printing equipment at room temperature of 20 degrees Celsius and 26 degrees Celsius. If this number is not reached, the fish must not be higher than 36 degrees Celsius at 16 degrees Celsius.

   2. Indoor humidity

   Most people know the space, the impact of Mirae chip mounter, but humidity also has a greater impact on product quality. High humidity components will not absorb moisture, especially the internal precision parts are sensitive to humidity, and if the paste absorbs moisture, it can also cause welding defects.

   Someone may ask, if humidity has such a big influence, is it okay to improve drying as much as possible? of course not. If the dryness is too high, static electricity may be generated when the air is dry. Some components, such as electrostatic discharge, are very sensitive to static electricity. Therefore, humidity control should also be in a balanced state. Topco engineers recommend that you control the indoor humidity at around 42-73R.

   Three, about cleaning

   If the Mirae chip mounter's working environment is dusty, it will affect the quality of the installation and welding of small parts such as 0201 and 01005 and thin-pitch (0.3 mm) parts. It will also increase the wear and tear of the equipment and may even cause equipment failure. Increase equipment maintenance and repair workload. In the smt production environment, in addition to dust, there may be some chemical gases in the week. If there are some harmful substances in these gases, it will cause certain harm to the human body; if these gases are corrosive, it will seriously affect the reliability of the product. Therefore, the working environment must be kept clean, dust-free, non-corrosive and odorless gas. This can ensure the welding quality of the product, the normal operation of the equipment and the health of the operators.

   The cleanliness of the general Mirae chip mounter plant is kept at a certain level, and it is more difficult to reach 10W, and the cost is relatively high. In order to achieve such an environment, because when the staff must be pumped into vacuum equipment, the entire factory is under negative pressure. In today's highly competitive market environment, this will generate a small profit. Few companies spend a lot of money to invest. Even if this requirement cannot be met, it is necessary to prevent cleanliness rules and regulations, such as the impact of cardboard dust, dust and carrying large objects, from entering the SMT workshop.
