Used HELLER reflow where _ in Xintai (certified) _ Used reflow provided by Shenzhen Electronic Equipment Co., Ltd. Xintai. Shenzhen Xintai Electronic Equipment Co., Ltd. (www.szzxtsmt.com) is specialized in the "medium and small reflow SMT production equipment research and development, production, sales and service" of the enterprise, the company of "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Chen Qicong. 1. What are the advantages of reflow technology? (1) When the reflow soldering technique, the printed circuit board does not need to be immersed in molten solder, instead of using the local heating manner of welding tasks; thus welded components used small thermal shock temperature reflow HELLLER will not cause damage to the components due to overheating. (2) Due to the welding technology need only cast solder in welding parts, and local heating complete reflow soldering HELLER hand how much money, thus avoiding bridges and other welding defects. (3) reflow technology, the solder is used once again to take advantage of the situation does not exist, therefore the solder is very pure, no impurities, ensuring the quality of solder joints. Note 42 reflow 1. To ensure personal safety, the operator must label and ornaments off, sleeves can not be too loose. 2 operation should pay attention to high temperature to avoid scalding Maintenance 3. can not arbitrarily set reflow temperature zones and speed 4. Make sure that indoor ventilation, exhaust chimney should lead to the outside windows. 3. reflow equipment maintenance system that we use over reflow after maintenance work to be done; otherwise it is difficult to maintain the life of the equipment. 1. Deal with the various components to be checked daily, with special attention to the transport network, it can not get stuck or fall 2 Used HELLER reflow When servicing machine operating procedures, should shut off the power to prevent electric shock or cause a short circuit 3. The machine must remain stable, not tilted or unstable phenomenon 4. Individual circumstances encountered heating zone stops, you should first check the corresponding fuse is by re-melting of pre-assigned to the standard technical parameters cream PCB pad: 1.
