Company Profile

Our Advantages

1 Strong production capacity
   More than 10 years industry experiences
   Excellent production technicians

2 Productive process  

1.   Design & Simulation

   •   The stator chip layout is designed using EDA (Electronic Design Automation) tools, incorporating circuitry for motor control, power      management, and sensor interfacing.

   •   Simulations verify electromagnetic compatibility (EMC), thermal performance, and signal integrity.

2.   Wafer Fabrication

   •   Silicon Wafer Preparation: High-purity silicon wafers are cleaned and polished.

   •   Photolithography: A photoresist layer is applied, exposed to UV light through a mask, and developed to create circuit patterns.

   •   Etching: Unwanted material is removed via dry (plasma) or wet etching to form transistors and interconnects.

   •   Doping: Ion implantation adjusts electrical properties of silicon regions.

   •   Deposition: Thin films (e.g., SiO₂, metal layers) are deposited using CVD (Chemical Vapor Deposition) or PVD (Physical Vapor     
       Deposition).

   •   Planarization: CMP (Chemical Mechanical Polishing) smooths surfaces between layers.

3.   MEMS Integration (Optional)

   •   For stator chips with integrated sensors (e.g., Hall effect sensors), MEMS (Micro-Electro-Mechanical Systems) techniques create 
       microscopic mechanical structures on the chip.

4.   Back-End Processing

   •   Dielectric Stacking: Insulating layers isolate metal interconnects.

   •   Metallization: Aluminum or copper layers form electrical pathways.

   •   Passivation: A protective coating (e.g., silicon nitride) shields the chip from moisture and contaminants.

5.   Testing & Dicing

   •   Probe Testing: Electrical probes validate functionality on the wafer.

   •   Wafer Dicing: Laser or diamond saw cuts the wafer into individual dies.

6.   Packaging

   •   The die is bonded to a lead frame or substrate (e.g., QFN, BGA).

   •   Wire bonding or flip-chip connects die pads to package terminals.

   •   Encapsulation with epoxy resin protects against environmental stress.

7.   Final Testing

   •   Burn-In Testing: Chips undergo thermal and electrical stress screening.

   •   Functional Testing: Motor control algorithms, PWM signals, and fault detection are validated.

   •   EMI/EMC Testing: Ensures compliance with electromagnetic standards.

8.   Integration into Motor Assembly

   •   The stator chip is mounted onto the drone motor's PCB, interfaced with coils, rotors, and power sources.

   •   Firmware is loaded to optimize motor efficiency and responsiveness.
