Why Is Particle Monitoring Necessary for Die Bonding Equipment?
Excessive particle concentration inside die bonding equipment may cause a variety of problems, including reduced product quality, equipment malfunction, electrostatic issues, and environmental safety risks.
Particles adhering to the surface of workpieces or materials may cause defects such as scratches, foreign particle spots, or uneven coating, which can affect product performance. They may also enter sensitive machine components, such as optical elements or sensors, leading to measurement errors or equipment damage. In addition, electrostatic effects may accelerate particle accumulation, creating a vicious cycle and potentially causing electrostatic discharge that damages electronic components.
Why Is It Needed?
Excessive Particle Concentration Inside Equipment Can Cause Process Defects!
In the CoWoS packaging process, particles adhering to chips may interfere with the operation of electronic components, reduce thermal conductivity, and significantly affect product quality.
Rapid temperature changes may cause uneven thermal expansion within the equipment, which can affect dimensional stability or even cause components to loosen or detach.
High humidity may also cause moisture condensation on the wafer surface, leading to changes in the oxide layer on the die and affecting chip performance.
Particles-IoT is primarily used to monitor and manage particle concentration inside die bonding equipment, helping prevent excessive particle levels from causing product defects or equipment abnormalities.
Particle counts continue to accumulate over time.
Why Is It Needed?
Prevent Product Quality Defects and Ensure Consistent Quality!
In the CoWoS packaging process, if particles (orange dots) inside a Die Bonder fall onto the Die Backside or Bond Pad, they may prevent the adhesive material from spreading evenly. Air pockets (voids) may form around the particles, potentially interrupting the heat dissipation path and resulting in reduced thermal performance.
By monitoring particle concentration through the Particle Monitoring IoT system, manufacturers can help prevent needle clogging, abnormal adhesive spreading, and void formation, thereby ensuring stable thermal conductivity and electrical connections.
When the precision nozzle of a Die Bonder performs die Pick & Place operations, particles can act like abrasive material. Excessive particles may accelerate nozzle wear and deform the nozzle tip profile. As a result, the nozzle may fail to accurately pick up the center of the die, causing die tilt or placement deviation. Particles trapped between the nozzle and die during pick-and-place operations may also cause scratches and wafer surface chipping.
The Particle Monitoring IoT system helps prevent nozzle wear and die scratches caused by excessive particle contamination.
Why Is It Needed?
Improve Flip Chip Process Yield and Reliability!
In the CoWoS packaging process, during high-precision die alignment and bonding in a Flip Chip Bonder, excessive particles in the environment can easily adhere to the surface of the die or substrate.
During the bonding process, these particles may become trapped between the bump and substrate, resulting in incomplete contact and causing open circuits or poor electrical contact. This may further affect the overall electrical performance of high-density packaging.
The Particle Monitoring IoT system helps track contamination trends, prevents particles from entering critical bonding interfaces, reduces the risk of electrical failure, and improves Flip Chip process yield and reliability.

Working Principle
High-Reliability Industrial Laser for Precise Measurement
Utilizing a Semiconductor Laser Source for High-Precision Measurement
Air is sampled using a pump, and when airborne particles pass through the laser beam, light scattering occurs.
The scattered light is then converted into an electrical signal (pulse) by a photoelectric converter.
Larger particles produce larger peak values in the pulse signal. By analyzing these peak values and the number of pulses,
the system determines the number of particles of different sizes.
