Xintai ZT-8030 medium in the basic principles of sixteen temperature hot air reflow Reflow is relatively simple, it first on the PCB surface mount components (SMD) pad printing paste, and then put through the automatic SMD placement machine pre-printed stickers put on a good solder pads. Finally, through the reflow oven, a hot air reflow oven gradually heated to melt the solder paste, known to reflux (Reflow), and then, the PCB board cooling, solidification of the solder reflow small, the element and the pad is securely welded to the together. In hot air reflow, pin pads and components do not melt. This is a hot air reflow (Reflow Soldering) Unlike metal melt welding (Welding) is. Depth understanding of physical and chemical changes must occur Reflow from the action principle and paste the welding process to start. Powder and flux paste composed mainly of tin-lead alloy mixture. Under conditions of heat, melt the solder material tin atoms and the pad or welded components (main ingredient is copper atoms) contact interface atomic interdiffusion to form intermetallic compound (IMC), Cu6Sn5 first formed, called the n- phase, which is the key to connecting layer welding force, only the formation of the n-phase reflow small wholesale, it represents a genuine and reliable welding. Over time, between the n-phase and will continue to generate the copper layer used in Xintai ZT-6030 mini-second temperature hot air reflow machine, supply sell used Nitto reflow - Used SMT Nitto Used seven-zone, eight-zone reflow and West used a semi-automatic eight-zone reflow solder paste printer only used eight-zone reflow Nichido Used eight-zone reflow soldering Nuo Sida Nitto leaded unleaded crest Welding Equipment Type: four to eight temperature zones Condition: Quantity more than 80% of new products: 10 Production Origin: Shenzhen Location: Shenzhen Processing range: second-hand electronic scrap equipment the company "professional assessment experience, reasonable acquisitions, integrity business attitude "long-term assessment of the recovery provinces and Shenzhen, Dongguan, Guangzhou, Huizhou, Zhongshan, Zhuhai and other electronic devices around the city, come to see goods valuation, professional recycling imports, domestic second-hand reflow, wave soldering hand, used smt full set of equipment, used Mounter, used AI machines, used printing presses, used various types of molding machines, used hardware equipment, used machinery, used plastics equipment, factory equipment auction reflow small amount of money, all kinds of air-conditioning equipment, various types of electronic materials Shenzhen Small reflow, waste materials: copper \ scrap \ scrap \ waste tin \ scrap tin slag, good or bad are closed, so that the idle assets to move in Xintai electronic equipment (Figure), small reflow temperature, small reflow provided by Shenzhen Xintai Electronic Equipment Co., Ltd.
