Precision Assembly
Surface Mount Technology (SMT) is a technology that put electronic components directly on the PCB surface. This technology uses automated equipment to accurately place the tiny electronic components on the PCB pad, and complete the assembly of the circuit board through the process of backwalm or peak welding. SMT technology has high degree of automation and accuracy, can effectively improve production efficiency and reduce human errors, so it has been widely used in modern electronics manufacturing.
We are equipped with the state-of-the-art manufacturing facility and sophisticated machinery to support the fabrication. We also have highly trained and experienced personnel to make sure your job is done faster with high quality. Our capabilities in high quality SMT pcb assembly services include, but not limited to:

24-hour rapid response to provide you with one-on-one nanny consultant pre-sales, sales, after-sales tracking service, for you to answer any difficult questions.
An SMT assembly line is automatic, including a loader, solder paste printing machine, SPI (solder paste inspection) machine, high-speed and functional mounting machines with feeders, reflow oven, and AOI (automatic optical inspection).
The SMT PCB assembly process is:
A loader sends a PCB into the solder paste printing machine, where an SMT stencil is set up. A scraper presses the solder paste to pass the holes of the SMT stencil and print on the PCB pads.
The PCB printed with solder paste passes the SPI machine, which quickly scans the solder paste and compares the thickness, position, and size of the solder paste with the set-up parameters. It ensures solderability.
The PCB with solder paste goes into a mounting machine, where a feeder sends SMDs to a position, and the nozzles of the mounter move to pick and place the SMD to a designated PCB pad one by one. The high-speed mounter picks and places SMDs with small footprints, such as resistors and inductors, while the functional mounter picks and places SMDs with larger footprints, such as connectors and ICs.
The PCBA enters a reflow oven, where it is preheated and baked. The reflow temperatures change according to the reflow profile. The solder paste melts to release the flux, which activates to facilitate the soldering. At the peak of reflow soldering, the PCB pads, solder paste, and SMD pins form metallic compounds, which marks the success of soldering. After that, the temperature goes down. The PCBA cools down and forms permanent joints.
The PCBA passes the AOI machine, which scans the entire surfaces of the PCBA and compares it with the reference. The AOI ensures almost all surface defects are identified and rectified, including soder bridges, voids, tombstones, etc.
SMT technology will continue to maintain its important position in the future and show multiple development trends.
1. With the continuous improvement of the miniaturization and integration of electronic products, SMT technology will further develop to meet the demand for smaller and more powerful components.
2. Intelligence will become an important development direction of SMT technology in the future. SMT technology will apply artificial intelligence and machine learning technology more to achieve automated production.
3. The improvement of environmental awareness will promote the use of more environmentally friendly production methods. The SMT industry adopts surface assembly to reduce lead pollution and harmful waste in traditional welding processes, which is more in line with environmental protection requirements.
4. The continuous development of intelligent manufacturing technology, the SMT industry will gradually realize digitization and intelligence. This will help improve production efficiency, reduce costs, and improve product quality, thereby enhancing the competitiveness of enterprises.
