(Summary description)SMT workshop preparation planning instructions SMT workshop planning manual, the following is a DEK + KE2050*2 + KE2060 + HELLER as an example. I. Preparation of power ; 1. DEK is a single-phase power supply, with ordinary plugboard. 2. as the power of JUKI KE2000 series is 3KW, the power of HELLER is 33KW, so it needs a 10KVA and a voltage regulator of more than 40KVA. 3. HELLER's power supply is 3-phase fire wire + 1 ground wire with a wire diameter of 25mm2. 4. JUKI's power supply for the 3-phase fire + 1 ground wire, the wire diameter of 6mm2. Second, the workshop preparation. 1. add a layer of transparent diaphragm adhesive before entering the SMT workshop, or make a locker room. 2. treat the ceiling accordingly to reduce the consumption of cold air. 3. According to the size of the equipment and the planning of the production line, calculate the area required for the workshop. Third, the preparation of air pressure 1. The outer diameter of the air trunk shall be 38mm, and the inner diameter of the flexible air pipe connected to the equipment shall be 12mm, and can withstand the pressure of 8Kg/mm2. 2. The working air pressure of the placement machine is 0.5Kg/mm2, so the * high air pressure of the compressor should reach 8Kg/mm2, gas flow 1.5mm3/min, power 15 horsepower, storage tank capacity of 2mm3, and equipped with a 2.5m3 dryer and two U-shaped filter. Fourth, the installation of air conditioning, and the installation of hygrometer and centigrade meter in the appropriate location, the workshop humidity in the middle of 50-70%, centigrade control in the middle of 18-25oC.
