SMT (Surface Mount Technology) production line and DIP (Dual In-line Package) production line are two different production lines in the electronic component manufacturing process.

The SMT production line completes assembly by directly mounting electronic components such as resistors, capacitors, and transistors onto the surface of a printed circuit board (PCB). This technology significantly improves production efficiency and assembly accuracy, while reducing assembly volume and weight. The SMT production line typically includes equipment such as PCB Printing Machine, PCB Pick and Place Machine, PCB Reflow Oven, SMT AOI.

The DIP production line inserts components into pre-drilled holes on the printed circuit board and then performs soldering. This technology used to be the main assembly method in the past but has gradually been replaced in modern electronics manufacturing. The DIP production line typically includes equipment such as an Automatic Insertion Line and a Wave Soldering Machine.

1 operator to oversee the entire production line, 1 assistant, totaling 2 personnel.

The Full-auto SMT Line involves a variety of equipment, including SMT Magazine Loader, Full-auto SMT Stencil Printer, 3D SPI, SMT Conveyor, 2 sets SMT Chip Mounter, SMT Reflow Soldering Oven (8-10 temperature zones), PCB Cooling Conveyor, Online SMT AOI, and NG/OK Unloader.

- PCB Magazine Loader
- SMT Printer
- 3D SPI

- SMT Conveyor
- 2 sets SMT Pick and Place Machine
- PCB Conveyor
- Reflow Oven (8-10 zones)
- PCB Cooling Conveyor

- In-line SMT AOI
- NG/OK Unloader

These SMT Machines can work efficiently together and produce high-quality routers, controllers, and set-top boxes in a short period of time, ensuring product quality and yield while reducing production costs.

SMT Magazine Loader: responsible for the first step of feeding the circuit board into the production line, can achieve fast and accurate board loading operation.
Full-auto SMT Stencil Printer: evenly applies solder paste on the circuit board to ensure a more secure connection between electronic components.
3D SPI: used to inspect whether the solder paste is evenly applied and to detect any defects, ensuring the quality of the pick-and-place process.
SMT Conveyor: serves as a bridge between various equipment and transfers the circuit board from one equipment to another.
SMT Chip Mounter: precisely place electronic components on the circuit board to achieve the functionality of the circuit board.
SMT Reflow Soldering Oven: heats and cools the solder joints to make the connection between electronic components and the circuit board more secure.
PCB Cooling Conveyor: cools the circuit board after reflow soldering and prepares it for the next step.
Online SMT AOI: uses high-resolution cameras to inspect whether the electronic components on the circuit board are correctly installed and connected, and whether there are any defects.
NG/OK Unloader: categorizes the inspected circuit boards as good or bad for further processing or repair.

5. DIP Line Solution

Personnel are adjusted according to the product, 8-20 people

After the surface-mounted components are installed, the PCB needs to enter the DIP production line. In the DIP production line, plug-in components such as IC chips and sockets are inserted into the PCB with the surface-mounted components already installed. Plug-in components are relatively large components that cannot be accurately installed on the PCB using SMT technology, so they need to be manually inserted.

- Wave Loader

- Wave Soldering Flux Independent Sprayer

- High-end Lead-free Wave Soldering Machine

- Wave Unloader

- 9m Belt Assembly Line

The DIP production line equipment for routers, controllers, and set-top boxes includes personnel adjustment based on the product, with 8-20 people. This production line is equipped with a series of devices, including a 9-meter PCB Insertion Line, Wave Loader, Wave Soldering Flux Independent Sprayer, a high-end Lead-free Wave Soldering Machine, Wave Uloader, and a 9-meter Bbelt Line.

Among them, the Wave Loader and Wave Unloader are essential equipment in the DIP production line, ensuring high efficiency and continuity throughout the production process. The Wave Soldering Flux Independent Sprayer can spray anti-oxidants during the soldering process to prevent components from being oxidized or otherwise damaged. The high-end lead-free wave soldering machine can achieve higher soldering efficiency and accuracy and is an important piece of equipment in the electronic manufacturing process.

In addition, the 9-meter insertion line and the 9-meter conveyor belt can meet the need for moving equipment during the soldering process, making it convenient for personnel to operate. 

In summary, the close coordination and collaboration of SMT and DIP processes are the keys to manufacturing high-quality, high-efficiency, and high-productivity products. When manufacturing electronic products such as routers, controllers, and set-top boxes, the mutual coordination and close connection of SMT production lines and DIP production lines can ensure product quality and production efficiency, thereby meeting the market's demand for high-quality electronic products.
