The ASM 03058631 is a high-precision Z-axis drive motor specifically engineered for the SIPLACE C+P20A (Collect & Place) rotary head. In a head array featuring 20 individual nozzles, the Z-drive motor must perform hundreds of thousands of vertical strokes per day with microscopic precision. This motor provides the rapid acceleration required to "descend, pick, and retract" in milliseconds, while maintaining the delicate control needed to prevent component cracking or solder paste displacement.
GEEKVALUE provides the P/N 03058631 with a focus on Dynamic Linearity. We understand that any variation in Z-axis torque can lead to inconsistent placement force; our motors are verified for uniform current-to-thrust performance, ensuring that your C+P20A head achieves a perfect "Soft-Landing" for every single component.

Strategic Performance Advantages
· Ultra-Low Inertia Rotor: The 03058631 features a lightweight rotor design that allows for instantaneous start-stop cycles. This minimizes the "settling time" at the bottom of the stroke, which is critical for maintaining high CPH (Components Per Hour) in high-density assembly.
· Precision Force Modulation: Optimized for ASM’s force-sensing logic, this motor enables the C+P20A head to execute the "Soft-Landing" protocol. By controlling the impact force during placement, it protects fragile ceramic capacitors and ultra-fine-pitch chips from structural damage.
· Thermal-Resistant Windings: Designed to reside within the tightly packed C+P20A head assembly, the 03058631 is built with high-grade thermal insulation. This prevents the motor from overheating during prolonged high-speed runs, ensuring the Z-height calibration does not drift due to thermal expansion.
· High-Resolution Feedback Sync: This motor is matched to high-fidelity encoders that provide real-time vertical position data. This allows the machine to compensate for PCB warpage on-the-fly, ensuring that the component is always released at the optimal focal plane.
The GEEKVALUE Advantage: "Vertical Precision"
1. 360° Total Cost Optimization (TCO)
Z-axis motor wear is often the hidden cause of "Mystery Rejects" and damaged components. GEEKVALUE optimizes your TCO by providing 03058631 motors that have undergone Vertical Stroke Endurance Testing. By ensuring consistent placement depth, we help you lower your scrap rates and minimize the need for manual inspection of delicate PCBA.
2. Trusted by 400+ Public Companies
Global leaders in high-end smartphone and automotive module production trust GEEKVALUE for their C+P20A head maintenance. Our P/N 03058631 is the go-to spare for listed companies that require "Zero-Defect" placement for their most complex high-density boards.
3. Smart Factory Ready
In an Industry 4.0 environment, placement force data is essential for quality traceability. GEEKVALUE’s 03058631 ensures that the Z-axis feedback remains accurate, providing the high-fidelity data needed for real-time process monitoring and predictive head maintenance.
Frequently Asked Questions (FAQ)
Q1: What are the symptoms of a failing C+P20A Z-Drive Motor (03058631)?
A: Common indicators include "Z-Axis Following Error," inconsistent placement depth (some components pushed too deep, others not touching the paste), or audible "buzzing" sounds coming from the head during operation.
Q2: Is this motor compatible with the SpeedStar or CP12 heads?
A: No. The 03058631 is specifically optimized for the C+P20 / C+P20A architecture. Using the wrong Z-drive can lead to synchronization errors or physical interference within the head assembly. GEEKVALUE’s technical team can help you verify your head type.
Q3: How does GEEKVALUE verify the "Soft-Landing" capability of this motor?
A: Every unit undergoes a Dynamic Torque-to-Force Test. We verify that the motor responds to low-current commands with the precise torque required for delicate placements, ensuring it meets the original ASM specifications for sensitive component handling.
Q4: Do I need to re-calibrate the head Z-height after replacement?
A: Yes. GEEKVALUE strongly recommends performing a "Z-Axis Height Calibration" and "Placement Force Verification" via the SIPLACE service software to ensure the new motor is perfectly synced with the machine’s vision and force sensors.
Q5: What is the packaging standard for this high-response drive?
A: We use Class-0 ESD and Precision Shock Protection. Every 03058631 is vacuum-sealed and housed in a reinforced, custom-fitted foam enclosure to ensure the delicate internal bearings and rotor alignment are preserved during shipping.
