Servo Axis and Suction Pressure Monitoring
Why is it needed?
Loader Motion Abnormalities?
A Crucial Link in the Process
In the die bonding process, the loader is responsible for separating individual dies from the wafer
and placing them onto the packaging substrate. This requires micron-level precision control and stability.
The loader’s motion axes operate under high-intensity continuous cycles. If motor operation becomes unstable or
fails, misalignment during wafer pickup can lead to defective products, increased scrap rates,
and production downtime.
Precise Control of Suction and Pressure
During the loader’s Pick & Place process, the suction nozzle relies on vacuum pressure to generate the necessary force
to move wafers or dies between locations. The level of vacuum pressure directly determines the nozzle’s gripping ability.
When the nozzle contacts the wafer surface, appropriate contact pressure must be applied to ensure secure handling.
Insufficient pressure may cause weak adhesion, leading to potential drop-offs, while excessive pressure can damage the
die, resulting in product defects and losses.

Does Pneumatic Cylinder Quality Affect Alignment?
Pneumatic Cylinder Malfunction Leads to Product Scrap!
In the die bonding process, the pressure applied by the pneumatic cylinder ensures
even distribution of solder and forms a secure connection at the weld points.
Various factors can cause pneumatic cylinder abnormalities, such as valve core blockage
due to oil contamination or valve wear, misalignment of the shaft preventing cylinder actuation,
or foreign object intrusion causing cylinder scoring.
When the pneumatic cylinder operates unstably, it can result in inaccurate die alignment,
affecting electrical connections and ultimately leading to product failure.

Ensuring the Quality of Loader Moving Axes
Red light indicates abnormal axis current signals

External clamp sensor for current measurement, no need for direct signal integration!
Start monitoring immediately, tracking X, Y, and Z motor current signals.
The motors driving the loader's moving axes power the Bond Head's movement.
When motors operate stably, the moving axes function smoothly. However, inadequate lubrication,
obstruction, or wear increases mechanical resistance, forcing the motor to draw more current
to maintain power output, which can result in excessive vibration.
Therefore, we use the DB-IoT Loader Quality Monitoring IoT to monitor changes in axis
current, enabling early detection of anomalies and ensuring stable loader operation.
