Scope

Main technical content: This standard specifies the materials and equipment, preparation requirements, quality control, safety and environmental protection, marking, labeling, packaging, transportation and storage, and file management requirements for the preparation of active metal brazing (AMB) ceramic substrates. Ceramic substrates and active metal brazing alloys must comply with corresponding standards. The preparation process covers multiple steps such as pre-treatment of ceramic substrates and active metal brazing coating, and clearly defines the parameters of each step. Quality control sets standards from multiple dimensions, such as the size limit of appearance defects and surface roughness (Ra≤0.8μm). In terms of safety, fire-prevention equipment must be installed in accordance with relevant standards; environmental protection requirements stipulate that pollutant emissions must meet standards. At the same time, detailed provisions are made for product marking, packaging, transportation and storage, and file management to ensure product quality and traceability.
