Fasteners for SiC Power Modules and Power Electronics

Silicon carbide (SiC) power semiconductor technology is becoming increasingly important in high-efficiency power conversion systems.

SiC power devices enable higher switching frequencies, higher operating temperatures, and improved power density. They are increasingly relevant to AI data centers, EV powertrains, charging infrastructure, renewable energy systems and industrial power electronics.

Although the semiconductor itself receives most of the engineering attention, the mechanical fastening system surrounding a power module is also critical.

Mechanical Requirements for SiC Power Electronics

SiC power modules can operate under demanding thermal and electrical conditions.

Mechanical components may need to withstand:

• Thermal cycling

• High temperatures

• Vibration

• Repeated maintenance

• High clamping requirements

• Tight dimensional tolerances

• Electrical insulation requirements

Fasteners are used to secure:

• Power modules

• Heat sinks

• Cooling plates

• Busbars

• Power electronics housings

• PCB assemblies

• Control modules

• Converter structures

JUXIN Fasteners for SiC Power Modules

JUXIN manufactures:

• Precision screws

• Custom bolts

• Stainless steel fasteners

• CNC machined parts

• Thread inserts

• Self-clinching nuts

• Rivet nuts

• Locking nuts

• Custom metal components

For power electronics applications, the appropriate material, coating and geometry should be selected according to the thermal and environmental conditions.

Thermal Management

Thermal interface structures require stable mechanical clamping.

Fasteners may secure:

• Heat sinks

• Cold plates

• Thermal spreaders

• Cooling channels

• Liquid cooling assemblies

Stable clamping can help maintain consistent contact between thermal components and the power module assembly.

Applications

• SiC power modules

• Inverters

• DC-DC converters

• AC-DC power supplies

• EV inverters

• Charging systems

• Solar inverters

• Energy storage converters

• AI data center power supplies

• Industrial drives
