The AMB precision brazing furnace has multiple advantages, mainly reflected in the following points:
1. Excellent vacuum environment: Adopting a multi-stage pumping system, high vacuum degree can be achieved, and the maximum vacuum degree can usually reach around 10 ?? Pa. In such a high vacuum environment, the oxidation pollution of active gases such as oxygen and nitrogen on the brazing material and substrate can be eliminated, avoiding the formation of oxide films on the metal surface during the welding process, thereby obtaining extremely clean and flux free brazed joints, ensuring welding quality. Meanwhile, high vacuum can also reduce the hindrance of gas molecules to the diffusion of active elements, accelerate interfacial reactions, and help improve the bonding strength between brazing materials and materials such as ceramics and metals.
2. Correct temperature control: Equipped with a high-precision temperature control system, such as PID closed-loop control, the temperature uniformity inside the furnace can be controlled within the range of ± 3-5 ℃, and the temperature can reach 1450 ℃. Heating elements are usually made of graphite heating elements or molybdenum wires, which have the characteristics of high temperature resistance and good thermal uniformity. In addition, multiple temperature rise insulation curves can be preset, supporting process parameter database management. Complex temperature control programs can be developed and executed correctly according to different brazing materials and process requirements, ensuring that the brazing process is carried out under ideal temperature conditions and improving the consistency and repeatability of brazing.
3. Good atmosphere control: Multiple atmosphere segments can be switched and controlled, and different protective gases such as argon and nitrogen can be introduced according to different brazing process requirements to further prevent material oxidation. At the same time, the chemical reactions during the brazing process can also be adjusted by controlling the atmosphere to meet the requirements of special brazing processes.
4. High precision form control: For brazing materials, the form control accuracy is high, and the thickness accuracy of brazing foil can reach ± 2 μ m. Alternatively, nano Ti particle modified brazing paste can be used to improve the uniformity of active element distribution, which helps to achieve high-quality brazed connections, reduce welding defects, and improve the strength and reliability of joints.
5. Low welding void rate: Some AMB precision brazing furnaces have unique structures and processes, such as equipped with dewaxing modules and fast cooling structures. By adjusting parameters such as brazing temperature, partial pressure, and fast cooling temperature, the welding void rate of the active metal solder layer in the AMB ceramic copper-clad substrate can be reduced, resulting in a fully dense welding layer, increasing the peel strength between the copper foil and the ceramic substrate, and improving the thermal shock performance.
6. High efficiency and energy saving: Using a unique integrated heating plate, the heating element and high-performance fiber insulation material are organically integrated, which greatly increases the heating rate. While achieving rapid heating, it reduces heat loss, achieves high efficiency, energy saving and time-saving effects, and reduces production costs.
7. High degree of automation: Equipped with an automated control system, it can achieve full monitoring and automated operation of the brazing process, reduce manual intervention, and improve production efficiency and product quality stability. At the same time, it is also easy to integrate with other production equipment to form automated production lines, meeting the needs of large-scale industrial production.
8. Customizable: We can provide furnace and shelf size customization services according to customers' different needs, better matching production and adapting to brazing workpieces of different specifications and shapes, with strong flexibility and adaptability.
9. Safe and reliable: Designed and manufactured in accordance with relevant standards, only those that meet the requirements of pressure vessels and pass pressure testing before leaving the factory. The electrical design and construction also comply with relevant standards to ensure the safe operation of equipment and reduce safety hazards. In addition, equipment is usually equipped with various safety protection devices, such as over temperature protection, vacuum leakage protection, etc., further improving the reliability and safety of the equipment.
