The welding temperature of molybdenum copper heat sink radiators is one of the most critical parameters in the welding process, which directly affects the welding quality and stability. For molybdenum copper heat sink radiators, selecting a suitable welding temperature requires consideration of multiple factors, including the properties of the welding materials, process requirements and specific application environment.
In general, MoCu heat sink radiators are usually used for heat dissipation of high-power electronic devices, such as power modules, power modules, etc. This heat sink is made of an alloy of molybdenum and copper. It has excellent thermal conductivity and mechanical strength and is suitable for high temperature and high power environments. During the welding process, appropriate solder is required to connect the heat sink to other components. Commonly used solders include solder, solder paste, etc.
The welding temperature for molybdenum copper heat sinks is generally between 200°C and 300°C. This range is relatively wide, and the specific welding temperature depends on multiple factors, including the requirements of welding materials, welding process requirements, and actual application requirements.
When determining the welding temperature, the following factors need to be considered:
Requirements for welding materials: Different solders may have different temperature requirements. Some solders require higher temperatures to completely melt and flow, while others can achieve good welding results at lower temperatures. Therefore, it is necessary to determine the appropriate welding temperature based on the selected solder.
Welding process requirements: The heat during the welding process will affect the heat sink and other components around it, which may cause problems such as thermal stress and deformation. Therefore, when determining the welding temperature, factors such as the heat capacity and thermal conductivity of the heat sink and other components need to be considered to ensure that the welding process is stable and reliable.
Requirements for the application environment: Different application scenarios may require different requirements for the connection strength, stability, and temperature resistance after welding. For example, electronic devices working in high temperature environments need to ensure that the connection after welding can withstand the influence of high temperature without loosening or breaking.

Therefore, when determining the welding temperature of the molybdenum copper heat sink, it is necessary to comprehensively consider the above factors and conduct sufficient experiments and verification. Generally, the appropriate welding temperature range can be determined based on the technical data and suggestions provided by the solder manufacturer, and adjusted and optimized according to the specific situation in actual operation to ensure welding quality and stability.
