Au cœur du système d'alimentation Shefmon : une conception de circuit imprimé sur mesure et un contrôle de l'alimentation garantissent des performances fiables pour les appareils de beauté.

A high-performance aesthetic machine depends not only on its external design but also on the stability of its internal electronic system. Shefmon’s supply system places strong emphasis on PCB design, power management, and component selection to ensure long-term reliability and consistent output. By upgrading core elements such as board thickness, IGBT modules, MOSFETs, and copper foil materials, Shefmon significantly enhances equipment durability, safety, and treatment effectiveness. This engineering-driven approach allows Shefmon to deliver machines that perform consistently even under demanding, high-frequency operating conditions.

1. Optimized PCB Structure for Long-Term Stability

1.1 Importance of PCB Thickness

PCB thickness plays a critical role in determining the durability and reliability of electronic systems, especially in devices that operate under continuous vibration and high-frequency output.

In many standard market solutions, PCB boards with a thickness of 1.6mm are commonly used. While this may reduce material costs, it introduces significant risks:

• Reduced resistance to vibration during operation
• Increased likelihood of PCB deformation or fracture
• Higher probability of circuit disconnection and functional failure

1.2 Shefmon’s 2.0mm Thickened PCB Design

Shefmon adopts a 2.0mm thickened PCB design to improve mechanical strength and operational stability. This enhancement provides measurable performance benefits:

• Approximately 40% improvement in bending resistance
• Greater durability under high-frequency vibration
• Reduced risk of structural failure over time

This upgrade ensures that the equipment maintains consistent performance even in intensive clinical environments.

2. Advanced Power Management with IGBT and Transformer Optimization

2.1 Limitations of Conventional Market Solutions

In many commercially available devices, low-frequency IGBT systems are used. These systems often suffer from:

• High operating temperatures exceeding 100°C
• Distorted output waveforms
• Unstable energy delivery during treatment

Such issues can negatively impact user experience, causing discomfort such as burning sensations or reducing treatment effectiveness.

2.2 Shefmon’s In-House Power Control System

Shefmon has developed its own MagSafe power management and system control PCBs, integrating high-frequency, low-loss IGBT technology with active cooling systems.

Les principaux avantages sont les suivants :

• Operating temperatures maintained at ≤70°C
• 20% improvement in waveform accuracy
• Stable high-frequency pulse output (50–100Hz)

2.3 Impact on Device Performance and Longevity

Stable waveform output is essential for magnetostimulation devices. Shefmon’s solution ensures:

• Consistent energy delivery without waveform distortion
• Elimination of excessive signal noise or clutter
• Reduced risk of overheating and burnout

With temperature rise controlled to ≤50°C, the system achieves more than three times the service life compared to conventional solutions.

3. Precision Current Control with High-Performance MOSFETs

3.1 Challenges with Standard MOSFET Configurations

Many devices on the market use low-voltage MOSFETs, which are prone to:

• Electrical breakdown under high load
• Current fluctuations exceeding 15%
• Sudden equipment shutdown or damage

These issues compromise both safety and treatment consistency.

3.2 Shefmon’s High-Voltage MOSFET Selection

Shefmon integrates high-voltage-resistant MOSFETs (≥60V) with low internal resistance into its PCB design. This ensures precise and stable current control.

Performance improvements include:

• Current fluctuation reduced to less than 5%
• Support for high-precision pulsed output modes
• Enhanced stability during intensive treatments

3.3 Real-Time Protection and Safety

Shefmon’s system includes real-time current monitoring and rapid overcurrent protection mechanisms.

Key safety features:

• Overcurrent response time ≤10ms
• Prevention of sudden current surges
• Protection against device burnout

This level of control significantly improves both safety and reliability in clinical applications.

4. Enhanced Conductivity with Upgraded Copper Foil

4.1 Limitations of Standard Copper Foil

Traditional PCB designs often use 1μm electrolytic copper foil, which has limited current-carrying capacity. Under high-load conditions, this can lead to:

• Overheating at solder joints
• Reduced heat dissipation efficiency
• Increased risk of circuit damage

4.2 Shefmon’s High-Conductivity Copper Solution

Shefmon upgrades its PCB boards with 2μm oxygen-free high thermal conductivity copper foil. This improvement delivers significant performance gains:

• 100% increase in current-carrying capacity
• 50% improvement in heat dissipation efficiency
• Enhanced resistance to thermal stress

4.3 Impact on High-Power Applications

In magnetostimulation devices where peak current is high, this upgrade ensures:

• Stable operation without overheating
• Extended component lifespan
• Reliable performance during continuous use

By eliminating overheating risks, Shefmon enhances both safety and device durability.
