Reputation depends on quality, quality comes from Hard!
Silicon Nitride Ceramic:
Stamping is mainly classified by process, which can be divided into two categories: separation process and forming process. The separation process is also Ceramic Substrate Hybrid Integrated Circuit Sheet called punching, and its purpose is to separate the stamping part from the sheet along a certain contour line while ensuring the quality requirements of the separated section. The surface and internal properties of the sheet metal used for stamping have a great influence on the quality of the stamped product. The thickness of the stamping material is required to be accurate and uniform; the surface is smooth, without spots, scars, scratches, and surface cracks, etc.; the yield strength is uniform and not obvious Directionality; high uniform elongation; low yield ratio; low work hardening. Stamping parts are mainly formed by stamping metal or non-metal sheet materials with the pressure of a press through a stamping die. It has the following characteristics: Stamping parts are manufactured by stamping under the premise of low material consumption. The parts are light in weight and rigid, and after the sheet Ceramic Substrate Hybrid Integrated Circuit Sheet metal is plastically deformed, the internal structure of the metal is improved, which improves the strength of the stamping parts. The stamping parts have high dimensional accuracy, the same size as the mold parts, and good interchangeability. It can meet general assembly and use requirements without further machining. During the stamping process, because the surface of the material is not damaged, the stamping parts have a good surface quality and a smooth and beautiful appearance, which provides convenient conditions for surface painting, electroplating, phosphating and other surface treatments. The designed stamping parts must meet the product use and technical performance, and be easy to assemble and repair. The designed stamping parts must be conducive to improving the utilization rate of metal materials, reducing material varieties and specifications, and reducing material consumption as much as possible. Use low-cost materials where permitted, and make the parts as waste-free and waste-less as possible. The designed stamping parts must be simple in shape and reasonable in structure, so as to simplify the mold structure and simplify the number of processes, that is, to complete the processing of the entire part with the least and simplest stamping process, reduce the use of other methods to process, and facilitate the stamping operation. Facilitate the organization of mechanized and automated production to improve labor productivity. The designed stamping parts, under the condition of ensuring normal use, try to make Ceramic Substrate Hybrid Integrated Circuit Sheet the dimensional accuracy level and surface roughness level as low as possible, and it is conducive to product interchange, reducing waste and ensuring stable product quality. The designed stamping parts should be conducive to the use of existing equipment, process equipment and process flow as much as possible to process them, and conducive to the extension of the service life of the die.
