High efficiency and energy saving, reduce maintenance requirements

　　Visionxp + "super first-class" reflow soldering system is equipped with EC motor, which is very in line with the trend of sustainable development. Special attention is paid to energy efficiency, emission reduction and operation cost reduction. The vacuum welding option can effectively reduce welding voids and create an efficient and stable production process for customers. With a variety of cooling options including bottom cooling, even heavy and complex circuit boards can be easily handled for efficient cooling.

　　Vacuum unit

　　In the visionxp + reflow welding system equipped with innovative vacuum unit, the solder is still in the molten state after high-temperature welding. At this time, it directly enters the vacuum unit to effectively solve the problems of pores, cavities and voids. There is no need for complex reprocessing of components through an external vacuum system.

　　Coolflow cooling scheme

　　In cooperation with Air Liquide, we have developed an innovative cooling technology. In order to make more efficient use of nitrogen as an inert gas, we have developed the first set of reflow welding system without water cooling through liquid nitrogen technology. The liquid nitrogen with temperature as low as - 196 ℃ forms strong cooling in the cooling area, and enters the furnace after heat exchange evaporation to form nitrogen to participate in the welding process. This technology can not only provide excellent cooling performance, but also meet the necessary inert process environment. At the same time, it does not need to consume a lot of energy for circulating cooling of cooling water, nor does it need additional cooling units and refrigerants.

　　Thermal decomposition system

　　During welding, impurities released from circuit boards, solder pastes or components must be filtered out of the process gas. Therefore, visionxp + is equipped with a residue management system for recovering and cleaning process gas. The system is composed of a pyrolysis device in the heating zone and a condensation filtration module in the cooling zone to ensure the effective removal of impurities in the process gas. The pyrolysis unit only needs to replace consumables once a year, which can greatly reduce the maintenance demand and shutdown time, and keep the furnace clean and dry for a long time.

　　SSP+

　　SSP + works on the same principle as SSP, but has more additional advantages. When the temperature difference of each heating area is high, the temperature will overflow from the high area to the adjacent area. Therefore, the area must be continuously actively cooled to ensure the required temperature curve. At this time, the internal exhaust system sucks ambient air with lower temperature through corresponding pipes to make each area reach accurate and stable temperature. In this way, the heat spilled from the high-temperature area can be greatly reduced to ensure more optimized area segmentation.
