Here’s an overview of every equipment used in SMT Machine Production Line:

1.Pick and Place Machine

Pick and Place Machine

Arguably the most important piece of equipment used in the SMT lines is the pick-and-place machine. This machine accurately places surface mount components on PCB pads – making sure all components are perfectly aligned and ready to be soldered together.

3 Types of Pick and Place Machine

In general, there are three different types of pick-and-place machines used by PCB manufacturers. Let’s go through each of them here:

1. Manual Pick and Place Machines:

These machines are operated by hand, requiring an SMT machine operator to place and secure components on the PCB. While they are affordable and simple to use, they can be time-consuming and less precise than automated options.

2. Semi-Automatic Pick and Place Machines:

These machines combine manual and automated functionality, with the operator manually placing components on the PCB and the machine using a vision system to ensure precise placement. This can be a more affordable and flexible option than fully automated machines, while still improving accuracy and efficiency.

3. Automatic Pick and Place Machines:

These machines use robotic arms and computer-controlled vision systems to automatically pick up and place components on the PCB. This allows for extremely high speed and accuracy, making it the preferred choice for large-scale and high-volume production. However, they can be expensive and require a significant initial investment.

2. SMT - PCB Magazine Loader & Unloader

SMT - PCB Magazine Loader & Unloader

Another one on our list is the SMT loader or the PCB magazine loader. It is responsible for automatically loading PCBs into the rack of a solder printing machine, making sure that each and every board is accurately placed. This helps speed up the entire process and saves time in manual setup. The PCB magazine unloader on the other hand is responsible for unloading the PCBs from the rack of a solder printing machine and placing them in designated holding bins. It avoids any unnecessary manual labor, ensuring that there is no wastage or delay in production. Both these systems are designed to increase productivity and reduce costs – an indispensable addition to any assembly line.

3.Solder Paste Printing Machine

Solder Paste Printing Machine

The next piece of equipment used in an SMT line is the solder paste printing machine. This is used to print the solder paste onto empty printed circuit boards and make sure everything is perfectly aligned before moving on to the next step. It is usually placed at the front of the pick-and-place machine.

4.Solder Paste Mixer

Solder Paste Mixer

A solder paste mixer is a great tool for achieving the perfect printing and reflow effects. It efficiently mixes the solder powder and paste evenly, which helps save labor and standardize this operation. In addition, it helps make sure that every solder joint is secure and reliable.

5.SMT Mounter Machines

SMT Mounter Machines

SMT mounter machines are precision industrial robots that utilize machine photoelectric and computer control technology to accurately and quickly attach SMC/SMD components to designated positions on printed circuit boards (PCBs). They achieve this through functions such as absorption, replacement, and positioning, while avoiding damage to the components and PCBs.

6.SPI Machine (Solder Paste Inspection)

SPI Machine (Solder Paste Inspection)

After doing the printing, it’s time to inspect the solder paste for any flaws. This is where the SPI machine comes in handy. It is used to check the thickness, area, and volume distribution of the solder paste printed on the PCBs – making sure that everything is up to standard before moving on to assembly.

7.Reflow Machine

Reflow Machine

Next up, we have the reflow machine. After the pick-and-place process, it is responsible for melting the solder and bonding components together to form a reliable electrical connection. It can be powered by hot air reflow, infrared reflow, or hot gas reflow – each offering different advantages in terms of speed and accuracy.

8.AOI - Automated Optical Inspection

AOI - Automated Optical Inspection

Commonly used before and after the reflow process is an AOI machine. It stands for Automated Optical Inspection and is used to detect placement failure of components before soldering in pre-solder inspection and soldering failure in post-solder inspection.

9.Docking Station

A docking station is basically a connection station between different machines in an SMT line. It helps to ensure that all components are properly connected and ready for assembly.


All listed above, the equipment and cost implications used in SMT production are essential for a reliable end product. From pick-and-place machines to ovens, each piece of equipment plays an important role in producing the best possible results.
