Chapter 41: IC Component Placement |
41.1 Chapter Summary |
This chapter examines the role of SCARA robots in the placement of integrated circuit components onto printed circuit boards. SCARA, which stands for Selective Compliance Assembly Robot Arm, is a robot design that has become a cornerstone of modern electronics manufacturing. The chapter begins with an overview of why SCARA robots are so well suited to this task, then moves through the mechanics of the robot, the nature of the components being placed, the programming and vision systems that guide the process, and a wide range of real-world applications across many industries. The goal is to give the reader a practical, non-mathematical understanding of how these machines work and where they are used. By the end of the chapter, the reader should appreciate not only the technical reasons for the SCARA robot's dominance in this niche, but also the breadth of industries that depend on it, from consumer electronics to automotive safety systems to medical devices and aerospace avionics. |

41.2 Introduction: The Heart of Electronics Assembly |
Every electronic device that a person touches in a day, from a smartphone to a kitchen appliance to a car's braking system, contains at least one printed circuit board. A printed circuit board, or PCB, is a flat board made of insulating material with conductive pathways etched or printed onto its surface. These pathways connect electronic components to one another. The components themselves include resistors, capacitors, diodes, transistors, and, most importantly for this chapter, integrated circuits. An integrated circuit, often called an IC or a chip, is a tiny piece of semiconductor material, usually silicon, that contains many electronic functions built into a single package. Placing these ICs onto a PCB accurately and quickly is one of the most important steps in electronics manufacturing. If a chip is placed even slightly off its intended position, the electrical connection may fail, and the entire board may be defective. |
For decades, the task of placing IC components onto PCBs was performed by human hands under microscopes. This was slow, tiring, and prone to error. As electronics became smaller and more complex, and as production volumes grew into the millions and then billions of units per year, manual placement could no longer keep up. The electronics industry turned to automation. Among the many types of industrial robots available, one design proved especially well suited to this task: the SCARA robot. |
|
41.3 What Is a SCARA Robot |
A SCARA robot is a mechanical arm with a specific arrangement of joints. The name describes its behavior. Selective Compliance means that the arm is stiff in some directions and flexible in others. Assembly Robot Arm means it was designed from the beginning with assembly tasks in mind. The typical SCARA robot has two or more horizontal arm segments joined by vertical axis rotary joints. The arm moves in a horizontal plane, which means it can swing left and right and extend and retract, but it does not easily move up and down except through a separate vertical axis. This design gives the robot high stiffness in the vertical direction, which is important for pressing components into place, while allowing fast, smooth motion in the horizontal plane. |
The SCARA configuration was developed in Japan in the late 1970s and early 1980s. It quickly found a home in electronics assembly because its strengths matched the needs of the industry almost perfectly. The robot could move very quickly over short distances, stop precisely, and repeat the same motion millions of times without variation. Its horizontal arm structure allowed it to reach into tight spaces above a PCB, and its vertical stiffness allowed it to push a component down onto a surface with controlled force. These characteristics made it ideal for pick-and-place operations, which is the technical term for picking up a component from one location and placing it in another. |
|
41.4 Why SCARA Robots Dominate IC Placement |
There are several reasons why SCARA robots are the preferred choice for IC component placement. The first is speed. In electronics assembly, every fraction of a second matters because production volumes are enormous. A single production line may place hundreds of thousands of components per hour. SCARA robots can achieve very high acceleration and deceleration rates because their moving mass is relatively low and their arm design is balanced. This allows them to move from one placement point to the next in a fraction of a second. |
The second reason is precision. Integrated circuits have leads or solder bumps that are extremely small, sometimes measured in tenths of a millimeter. The robot must place the component so that these leads align with the corresponding pads on the PCB. A SCARA robot can achieve repeatability of a few thousandths of a millimeter, which means it can return to the same position over and over with almost no variation. This level of precision is essential for modern electronics. |
The third reason is mechanical simplicity and reliability. A SCARA robot has fewer joints and linkages than many other robot configurations, such as articulated arms with six axes. Fewer moving parts mean less wear, less maintenance, and lower cost. In a factory that runs twenty-four hours a day, reliability is critical. A robot that breaks down frequently would stop the entire production line. |
The fourth reason is the robot's ability to work in clean environments. Electronics assembly often takes place in cleanrooms where dust and other particles are controlled. SCARA robots can be designed with sealed joints and smooth surfaces that do not generate particles, making them suitable for these environments. |
The fifth reason is cost. SCARA robots are generally less expensive than comparable six-axis robots. For a task that only requires movement in a horizontal plane plus a vertical stroke, a SCARA robot provides exactly the right capabilities without paying for extra axes that are not needed. |
|
41.5 The Anatomy of a SCARA Robot Used for IC Placement |
A typical SCARA robot used for IC placement consists of several key subsystems. The base is the stationary part that mounts to a table or frame. Inside the base are the motors and gear reducers that drive the arm. The first arm, sometimes called the inner arm or link one, rotates around a vertical axis at the base. The second arm, or outer arm, rotates around a vertical axis at the end of the first arm. At the end of the second arm is a vertical axis that moves a tool up and down. This tool is usually a vacuum nozzle or a gripper. |
The vacuum nozzle is a small tube connected to a vacuum source. When the nozzle touches a component, the vacuum holds the component against the tip. When the robot reaches the placement location, the vacuum is released, and the component is left in place. Some systems use a mechanical gripper instead of a vacuum nozzle, especially for larger or heavier components. The choice depends on the size and shape of the component and the requirements of the application. |
The robot also has a controller, which is a computer that sends commands to the motors. The controller receives information from sensors, such as encoders that measure the angle of each joint. Using this information, the controller calculates the exact position of the tool tip and adjusts the motor commands to move the tool to the desired location. This process is called closed-loop control. It allows the robot to compensate for small errors and maintain accuracy over long periods of operation. |
Many SCARA robots used for IC placement also have a vision system. A camera is mounted near the tool or above the PCB. The camera takes an image of the component or the placement location, and software analyzes the image to determine the exact position and orientation. This information is sent to the controller, which adjusts the robot's motion to align the component correctly. Vision systems are essential for placing fine-pitch components, where the leads are very close together and alignment must be extremely precise. |
|
41.6 The Components Being Placed |
The components placed by SCARA robots come in many shapes and sizes. The most common types include surface mount devices, ball grid arrays, quad flat packages, and chip scale packages. Surface mount devices, or SMDs, are components that are soldered directly onto the surface of the PCB rather than through holes. They include resistors, capacitors, and small integrated circuits. Ball grid arrays, or BGAs, are packages where the connections are made through an array of small solder balls on the bottom of the package. Quad flat packages, or QFPs, have leads extending from all four sides. Chip scale packages are nearly the same size as the semiconductor die itself, making them extremely small and challenging to place. |
Each of these component types presents different challenges for the placement robot. BGAs, for example, require very precise placement because the solder balls are hidden underneath the package and cannot be inspected visually after placement. QFPs require the leads to be aligned with pads on the PCB, and any bending of the leads can cause a defect. Chip scale packages are so small that the robot must handle them with extreme care to avoid damage. SCARA robots are used for all of these component types because they can be programmed to apply the right amount of force, move at the right speed, and align with the right precision for each type. |
|
41.7 The Pick-and-Place Process Step by Step |
The pick-and-place process performed by a SCARA robot can be broken down into a sequence of steps. First, the robot moves its tool to the component pickup location. This location may be a tray, a tape and reel feeder, or a waffle pack. A tape and reel feeder is a common method where components are held in pockets in a long strip of tape that is wound on a reel. The feeder advances the tape to present the next component to the robot. A waffle pack is a tray with small compartments, each holding one component. |
Second, the robot lowers its tool to the component. If a vacuum nozzle is used, the nozzle touches the top of the component, and the vacuum is turned on. The robot then lifts the component. Third, the robot moves the component to a position above the placement location on the PCB. During this move, the vision system may take an image of the component to determine its exact orientation. If the component is slightly rotated or offset, the robot adjusts its motion to correct for this. |
Fourth, the robot lowers the component to the PCB surface. The force applied during this step is carefully controlled. Too much force can damage the component or the PCB. Too little force can result in the component not making proper contact. Fifth, the vacuum is released, and the component is left on the PCB. The robot then moves to pick up the next component. This entire sequence may take only a fraction of a second, and it is repeated thousands or millions of times per production run. |
|
41.8 Programming and Control |
Programming a SCARA robot for IC placement involves teaching the robot the positions of the pickup locations and the placement locations. This can be done in several ways. One method is lead-through teaching, where a human operator physically moves the robot arm to the desired positions and records them. Another method is offline programming, where the positions are defined in a computer model of the workcell and then downloaded to the robot controller. A third method is vision-guided programming, where the robot uses camera images to automatically determine the positions of components and placement locations. |
The control system of a SCARA robot must coordinate the motion of multiple joints to achieve the desired tool position. This is done using kinematic equations, which describe the relationship between joint angles and tool position. The controller also must plan the trajectory of the tool, meaning the path it follows from one point to another. The trajectory must be smooth to avoid jerking motions that could shake the component loose or cause the robot to overshoot. The controller uses acceleration and deceleration profiles to ensure smooth motion. It also must synchronize the robot's motion with the operation of the feeders and the conveyor that moves the PCBs through the production line. |
Modern SCARA robot controllers often include features such as collision detection, which stops the robot if it senses an unexpected force, and force control, which allows the robot to apply a specific force during placement. These features improve reliability and reduce the risk of damage to components and equipment. |
|
41.9 Vision Systems and Alignment |
Vision systems have become increasingly important in IC placement as components have become smaller and more densely packed. A typical vision system consists of one or more cameras, lighting, and image processing software. The cameras may be mounted on the robot arm, looking down at the component or the PCB, or they may be mounted in a fixed position, looking up at the component as the robot passes over. |
The vision system performs several functions. It identifies the component and checks that it is the correct type. It measures the position and orientation of the component relative to the robot's tool. It measures the position of the placement location on the PCB, which may vary slightly from board to board due to manufacturing tolerances. It then calculates the correction needed to align the component with the placement location. This correction is sent to the robot controller, which adjusts the robot's motion accordingly. |
Lighting is a critical part of the vision system. Different lighting techniques, such as backlighting, coaxial lighting, and ring lighting, are used to make the features of the component and the PCB stand out clearly. Backlighting, for example, creates a silhouette of the component, making it easy to measure its outline. Coaxial lighting illuminates the surface directly, which is useful for reading markings on the component. |
|
41.10 Applications in Consumer Electronics |
The consumer electronics industry is one of the largest users of SCARA robots for IC placement. Smartphones, tablets, laptops, televisions, and wearable devices all contain PCBs with many integrated circuits. The production volumes in this industry are enormous. A single smartphone model may sell tens of millions of units, and each unit contains multiple PCBs. To meet this demand, manufacturers use high-speed placement machines, many of which are based on SCARA robot technology. |
In smartphone manufacturing, SCARA robots place components such as the application processor, memory chips, power management ICs, and radio frequency chips. These components are often very small and require precise placement. The robot must also handle the high speed required to keep up with the production line. Vision systems are used to align the components, and the robots are programmed to place them with accuracy measured in tens of micrometers. |
In television manufacturing, SCARA robots place components on the main board, the power supply board, and the display driver board. These boards are larger than those in smartphones, but the components are still small and require precise placement. The robots must also handle the weight of larger components, such as power transistors and heat sinks, which may require a different type of gripper. |
In wearable device manufacturing, such as smartwatches and fitness trackers, the PCBs are very small and densely packed. SCARA robots with fine resolution and high precision are used to place the components. The small size of the boards means that the robot must be able to reach into tight spaces and place components with extreme accuracy. |
|
41.11 Applications in Automotive Electronics |
The automotive industry uses SCARA robots for IC placement in a wide range of electronic systems. Modern cars contain dozens of electronic control units, or ECUs, which control everything from the engine to the brakes to the entertainment system. Each ECU contains a PCB with many integrated circuits. SCARA robots are used to place these components. |
One important application is in the manufacturing of airbag control modules. These modules contain sensors, microcontrollers, and power management ICs. The reliability of these components is critical because they are part of a safety system. SCARA robots place the components with high precision and repeatability, and the vision systems verify the placement before the board moves to the next stage. Another application is in the manufacturing of anti-lock braking systems, or ABS. The ABS control module contains a microcontroller and several power ICs that must be placed accurately. SCARA robots are used because they can handle the fine-pitch components and the high production volumes required by the automotive industry. |
Automotive electronics also include infotainment systems, navigation systems, and advanced driver assistance systems, or ADAS. These systems contain powerful processors, memory chips, and communication ICs. SCARA robots place these components on the PCBs. The automotive industry requires high reliability and long product lifetimes, so the placement process must be tightly controlled and documented. |
|
41.12 Applications in Medical Devices |
The medical device industry uses SCARA robots for IC placement in devices such as pacemakers, implantable defibrillators, hearing aids, and diagnostic equipment. These devices often have stringent requirements for reliability and cleanliness. A pacemaker, for example, must function reliably for many years after being implanted in a patient. The PCBs inside a pacemaker contain microcontrollers, memory chips, and communication ICs. SCARA robots place these components in a cleanroom environment to avoid contamination. |
Implantable defibrillators are similar to pacemakers but have additional components for delivering a shock to the heart. The PCBs in these devices are densely packed, and the components must be placed with high precision. SCARA robots are used because they can handle the small components and the strict quality requirements. |
Hearing aids are another important application. These devices are very small and contain a microphone, a signal processor, an amplifier, and a speaker. The PCBs inside a hearing aid are among the smallest in the electronics industry. SCARA robots with high-resolution vision systems are used to place the components. The robots must be able to handle the tiny components without damaging them. |
Diagnostic equipment, such as blood glucose monitors, ultrasound machines, and magnetic resonance imaging, or MRI, scanners, also contains PCBs with integrated circuits. SCARA robots place the components on these boards. In some cases, the boards are large and contain many components, while in other cases they are small and densely packed. The robot must be flexible enough to handle both types of boards. |
|

Motor drives are used to control electric motors in industrial equipment. They contain power ICs, microcontrollers, and sensors. SCARA robots place these components on the PCBs. The power ICs may be larger and heavier than other components, so the robot must be equipped with a suitable gripper and force control. |
Sensors used in industrial automation, such as proximity sensors, photoelectric sensors, and pressure sensors, also contain PCBs with integrated circuits.

|
41.20 The Role of Feeders and Material Handling |
SCARA robots do not work alone. They are part of a larger system that includes feeders, conveyors, and other material handling equipment. Feeders present components to the robot in a known position and orientation. The most common types of feeders for IC placement are tape and reel feeders, tray feeders, and tube feeders. |
Tape and reel feeders are used for small components that are supplied in a continuous strip. The tape has pockets that hold the components, and a cover tape protects them. The feeder advances the tape to present the next component to the robot. Tray feeders, also called waffle packs, are used for larger components or components that cannot be supplied in tape. The tray has compartments that hold the components. Tube feeders are used for components that are supplied in long tubes. The feeder tilts the tube to allow the components to slide out one at a time. |
Conveyors move the PCBs through the production line. The SCARA robot is typically mounted above the conveyor, and the PCB stops at a precise location for the placement operation. The conveyor must be able to position the PCB accurately and hold it steady during placement. |
|
41.21 Quality Control and Inspection |
Quality control is a critical part of IC placement. After the components are placed, the PCB is inspected to ensure that all components are present, correctly oriented, and properly aligned. Inspection can be performed by human operators, but in high-volume production, automated optical inspection, or AOI, is used. AOI systems use cameras and software to compare the PCB to a reference image and identify defects. |
SCARA robots can be integrated with AOI systems to provide feedback and correction. If the AOI system detects a placement error, it can send a signal to the robot controller to adjust the placement process. This closed-loop quality control helps to reduce defects and improve yield. |
In addition to AOI, X-ray inspection is used for components such as ball grid arrays, where the solder joints are hidden underneath the package. X-ray inspection can reveal voids, cracks, and other defects in the solder joints. SCARA robots place the components, and the X-ray system inspects them. |
|
41.22 Challenges and Limitations |
Despite their many advantages, SCARA robots have limitations. One limitation is their working envelope. The arm of a SCARA robot moves in a horizontal plane, and the reach is limited by the length of the arms. For very large PCBs, a SCARA robot may not be able to reach all areas of the board. In these cases, a gantry robot or a different configuration may be used. |
Another limitation is the payload capacity. SCARA robots are designed for lightweight components. If a component is too heavy, the robot may not be able to lift it or may lose accuracy. For heavy components, a different type of robot or a custom end effector may be needed. |
A third limitation is the need for precise calibration. SCARA robots must be calibrated regularly to maintain accuracy. The calibration process involves measuring the actual position of the tool tip and comparing it to the commanded position. Any discrepancy is corrected in the controller. If calibration is not performed, the robot may place components in the wrong position. |
A fourth limitation is the cost of vision systems and feeders. While the SCARA robot itself may be relatively inexpensive, the vision system, feeders, and other peripherals can add significantly to the total cost of the system. For low-volume production, the cost may not be justified, and manual placement may be more economical. |
|
41.23 Recent Developments and Future Trends |
The field of IC placement is constantly evolving. Several recent developments are shaping the future of SCARA robots in this application. One trend is the increasing use of collaborative robots, or cobots. Cobots are designed to work alongside humans safely. Some cobots use a SCARA-like configuration. They can be used for IC placement in low-volume, high-mix production environments where flexibility is more important than speed. |
Another trend is the integration of artificial intelligence and machine learning into vision systems. AI-powered vision systems can learn to recognize components and detect defects more accurately than traditional rule-based systems. They can also adapt to changes in lighting and component appearance. This improves the reliability of the placement process. |
A third trend is the development of higher-speed and higher-precision SCARA robots. Manufacturers are continually improving the motors, gear reducers, and controllers to achieve faster cycle times and better accuracy. This is driven by the ever-increasing demand for smaller, more complex electronic devices. |
A fourth trend is the use of digital twins and simulation. Before a production line is built, engineers can create a digital twin, which is a computer model of the line. They can simulate the operation of the SCARA robots and optimize the placement process. This reduces the time and cost of setting up a new production line. |
A fifth trend is the increasing use of modular and reconfigurable systems. Instead of a fixed production line, manufacturers are using modular systems that can be quickly reconfigured to produce different products. SCARA robots are well suited to this approach because they can be easily reprogrammed and moved. |
