Product Description
Power & Thermal SMT Nuts | Integrated Electrical-Thermal Bridge Solutions
1.SMT NutsQuick Detail
When your application requires not just mechanical connection but also involves high current transmission or efficient heat dissipation, our functional SMT nuts provide an integrated solution. Manufactured from highly conductive/thermally conductive materials (e.g., copper, aluminum) and featuring large-area solder designs, they can establish a low-resistance, efficient electrical or thermal bridge on the PCB. This simplifies traditional designs that require extra bus bars or thermal pads, achieving a dual enhancement of performance and reliability within a compact space.
2.SMT NutsProduct Description
In modern high-power-density electronic devices, thermal management and power integrity are core challenges. Our high-current/high-thermal-conductivity patch nuts are designed to address these issues. They cleverly transform a standardized threaded connector into a multi-functional platform. Through its metal body, current can be distributed more evenly and with lower loss; heat can be conducted more directly from the heat-generating chip (via the connecting screw and nut) to the heatsink or underlying PCB copper foil. We work closely with our customers to optimize the nut's material, shape, and solder interface based on specific current requirements, thermal dissipation, and space constraints, making it an efficient "hub" in your power circuits or cooling systems.
3.SMT NutsProduct Features & Advantage
|
Feature |
Advantage to You |
|
Excellent Electrical & Thermal Conductivity |
Use of pure copper or high-conductivity aluminum alloys significantly reduces connection resistance and thermal resistance, improving system efficiency, helping cool power devices, and extending lifespan. |
|
Maximized Solder Interface & Current Path |
Designed with wide solder wings or large bottom areas, providing greater solder contact area, increasing current-carrying capacity, and reducing current density for higher reliability. |
|
Simplified System Structure & Assembly |
One nut simultaneously achieves mechanical fixation, electrical connection (grounding/power), and thermal conduction, reducing part count and simplifying BOM and assembly steps. |
|
Optimized CTE Matching & Stress Management |
Based on the CTE of the PCB and heat dissipation material, a suitable nut material (such as aluminum matching aluminum substrate) can be selected to reduce thermal cycling stress and improve long-term reliability. |
|
Flexible Integrated Design Options |
Can provide versions with insulating coating or integrated ceramic washers, enabling efficient heat conduction with electrical isolation, meeting insulation requirements of complex systems. |

5.SMT NutsProduct Application
Functional surface mount nuts are invaluable assets in power electronics and thermal management systems:
Electric Vehicle Control Systems: Used for connecting and conducting heat between the IGBT module heat sink and the PCB in the motor controller (MCU), enabling low-inductance, high-efficiency power circuits and heat dissipation.
Server and Data Center Power Supplies:Serving as a grounding and heat dissipation connection point for the DC-DC converter module in server power units (PSUs), facilitating high-current transfer and heat dissipation.
Renewable Energy Inverters: Used for heat sink mounting on photovoltaic/energy storage inverter power boards, while also providing a stable grounding path to handle current and heat at high switching frequencies.
High-Power LED Lighting:** Serving as a fastener for the heat sink substrate on LED driver boards, ensuring both secure mounting and efficient heat transfer from the LED chip to the heat sink.
