1. SMT:


Surface mount technology, SMT for short, is an electronic mount technology that mounts resistors, capacitors,


transistors, integrated circuits and other electronic components on a printed circuit board and forms electrical


connections through soldering.



2. The advantage of SMT:


      SMT products have the advantages of compact structure, small size, vibration resistance, impact resistance, good high-frequency


      characteristics,and high production efficiency. SMT occupies a place in the circuit board assembly process.


3. Mainly steps of SMT:


     The SMT production process generally includes three main steps: solder paste printing, placement and reflow soldering.


      A complete SMT production line including basic equipment must include three main equipment: printing machine, production


      line SMT placement machine and reflow soldering machine. In addition, according to the actual needs of different production,


      it can also be equipped with wave soldering machines, testing equipment and PCB board cleaning equipment. The design of


      SMT production line and equipment selection should combine the actual needs, actual conditions, and adaptability of product


      production to produce advanced equipment.



4. Our capacity: 25 sets


       High speed


       Brand: Yamaha, JUKI, Hitachi, Ambian


5. The Difference between SMT & DIP


       (1) SMT generally mount lead-free or short lead surface mount components. The solder paste needs to be printed on the PCB,


            then mounted by the placement machine, and then fixed by reflow soldering; there is no need to reserve corresponding


            through holes for the pins of the components, and the component size of the surface mount technology is much smaller


            than the through-hole insertion technology .


       (2) DIP soldering is to directly encapsulate the packaged device, which is fixed by wave soldering or manual soldering.
