Huagon SMT factory's overview

Anna original 2023-03-28 16:38:19

     Shenzhen Huagon Technology Co., Ltd. has been engaged in wireless charging designing and production since 2013 equipped with a R&D team, a SMT factory and an assembly plant.
A brief introduction of our SMT factory. With a 5000 ㎡SMT workshop, our daily delivery for PCBA module reaches over 40,000 pieces.The SMT equipment are listed as belows:
4 ✖ Boarding Machine    DIMEI  DM-900B        
8 ✖ Fully Automatic Paste Printer    HTGD  GD450+        
8 ✖ High-speed mounter (SMT)    Yamaha YS24+YS20+YSM10    
2 ✖ Reflow Solder    Jaguar R10-D        
3 ✖ First piece tester    Bluiris        
7 ✖ Automatic chip burner     Kincoto    
3 ✖ Automatic optical inspection  AOI

      Firstly, what is SMT? SMT refers to Surface Mount Technology (SMT). It is the method used to mount electrical components directly onto the surface of a PCB. Our factory has 4 SMT lines altogether. 

    The whole surface mount technology begins with the boarding machine. The boards are placed into the boarding machine one by one and raced into the paste printer. Then comes the stenciling solder paste. Think of it like screen-printing a t-shirt, only instead of ink, SMT uses a solder paste to print the paste, and then the pick and place machines place the parts on the board. Here we see a computer used for controlling the Paste Printer HTGD450+ to solder the tin paste into the circuit board where it is needed.

    The Paste Printer applies the solder paste evenly on the board so that the components can be tightly stuck into the circuit board after they are mounted into the board later. The next part of the line is SMT machine, Yamaha YS24, which picks and places the electric components onto the circuit board with paste. Each machine can do 80,000 components per hour. It picks the components and mounts them on the board at very accurate position. We divide the mounting work into 2 different machines. 

    After the electronic components are mounted, they will be transferred into the reflow oven, Jaguar R10-D, which contains the heating area and cooling area. The heating area melt the fine solder paste into a fine solder. The cooling area cools the pcb into the normal temperature. Finally, a finished product comes out and waits to be piled into the shelf and to the next stage. The next stage is quality control inspect, first inspected by the machine ZW-625, using AOI test, (automated optical inspection test), then examined by workers one by one. Multiple inspection points to ensure the highest quality at every stage of manufacturing. Once the defect ones are found, they will be sent to the repairing room to be repaired by our repairman.

     Then comes our back welding workshop with 4 lines of more than 60 workers. Their work includes welding the bigger parts that the SMT machines can’t do, cutting down the extra parts, charging the pcb and examine with the loader to see whether they work fine, wrapping the final products with protective plastic and paper boxes.
