Analysis of the Five Core Modules of Samsung Surface Mount Technology (SMT) Machines: No Part Is a "Supporting role"

When it comes to surface mount technology (SMT) placement machines, everyone knows that they are the "heart" of the SMT production line. It is a common operation to place hundreds of components in one second. But have you ever wondered in which key modules this high-precision and high-efficiency machine truly excuses?

Today, let's talk about the five core modules of Samsung's surface mount technology (SMT) machines. Who is working behind the scenes and who is quietly taking on the big tasks? Don't be fooled by the fact that each part may seem insignificant; every one is the star!

Whether the patch can be applied well or not depends on whether the feeding is accurate or not.

The feeding system, to put it simply, is responsible for delivering components one by one to the mouth of the suction nozzle.

The feeding systems of Samsung's surface mount technology (SMT) machines come in various types, such as 8mm, 12mm, 16mm, etc. Different material tapes are equipped with different feeders. Many people underestimate feeder. In fact, once it has a problem, the entire production line has to be shut down. For example:

• Material jamming: At the very least, it may result in an error; at the worst, it may lead to incorrect component placement.
• Inaccurate step: The position is off, and the suction nozzle cannot reach the components.
• Unstable tension: This causes the material tape to be pulled too loosely or too tightly, affecting identification.

So, feeder is not a supporting role; it is the "first threshold" for the accuracy of the patch.

Machine surface mount technology (SMT) is not done randomly; it has to "see clearly" where and what to apply. At this point, it's the visual system that comes into play.

The vision system of Samsung's surface mount technology (SMT) placement machine

The vision system of Samsung surface mount technology (SMT) machines generally consists of two parts:

• Upper visual inspection: Check if the components are held correctly, if the model is correct, and if there are any missing corners.
• Below: Determine the position and coordinates of the PCB to ensure that components are placed in the correct positions.

Some models are also equipped with a flight vision system (taking photos during flight), which can identify while moving, greatly improving efficiency. Once the visual system malfunctions, such as dust blocking the lens or unstable lighting, the following will occur:

• Component identification error;
• Offset;
• The mounting is skewed or the position is incorrect.

To put it simply, the visual system is like the "eyes" of a surface mount technology (SMT) placement machine. The clearer it is, the more accurate the placement will be!

Whether the surface mount technology (SMT) machine can stick the surface mount accurately or not all depends on the nozzle system.

The suction nozzles of Samsung surface mount technology (SMT) machines are generally installed on the mounting heads. They use vacuum suction to hold the components and then precisely move them onto the PCB for mounting. One mounting head may be equipped with several suction nozzles, and when it comes to work, it is at the "octopus" level of efficiency.

When there is a problem with the suction nozzle, the following symptoms usually occur:

• Unable to suck up materials (unstable vacuum, blocked head);
• Component drops (insufficient suction or too fast movement);
• Misalignment (loose suction tip or Angle deviation).

Therefore, during maintenance, the suction nozzle must be regularly cleaned and the vacuum pipeline inspected; otherwise, it may take an entire morning to stick several boards.

Don't forget that there is another module that is often overlooked, and that is the transmission system.

Its task is to stably send the PCB board in and out, and at the same time, keep it stable and stationary during the mounting process.

The transmission system includes:

• "Track;
• Motor drive;
• Splint device.

If the transmission is not smooth, it will lead to:

• The PCB is stuck in the machine.
• The board was not aligned properly, resulting in an offset in the mounting position.
• The uneven surface of the board affects the installation height of the suction nozzle.

This is like a running race. If the track is uneven, the runners can't perform well either, right?

Finally, and most crucially, the control system can be said to be the brain of the surface mount technology (SMT) machine, coordinating all actions, parameters and processes.

Samsung surface mount technology (SMT) machines are generally equipped with professional operating systems, such as SIPLACE or its own Hanwha software platform, which are responsible for controlling:

• Feeding sequence;
• Suction nozzle movement path
• Mounting sequence and coordinates;
• Fault alarm, visual recognition parameters, etc.

The operator sets the program through the control system and runs it with one click, and the entire process begins.

Once the software malfunctions, such as program errors, communication anomalies, or version incompatibility, the entire surface mount technology (SMT) machine will fail.

Therefore, the control system is not only the "central console", but also the "command center" where all modules work in coordination.

The five major modules are all important

Let's review it again

So don't say that a certain part is a "supporting role" anymore. In the "team" of the surface mount technology (SMT) machine, every component is the main force and no one can be missing!

One final reminder:

In the daily use of the surface mount technology (SMT) machine, don't wait until it "falls ill" to check for problems. Regular maintenance and inspection of all major modules can ensure that your production line runs fast and stably!

If you are an equipment engineer, technician, or production supervisor, you might as well make a checklist for these five modules and conduct an inspection once a week. Early detection of problems can significantly increase efficiency!
