Optical communication industry: In the era of big data, a large number of optical communication modules are used in supercomputing centers, data centers, 5G base stations,etc. The MIM technology, due to its cost-effectiveness and higher productivity,has been adopted in the manufacturing of the core structural parts of themodules, gradually replacing traditional processes. At present, tungsten copperalloy, kovar alloy and stainless steel can be MIM processed, which have been extensively used in various kinds of modules such as Tosa Base, Rosa Base, Housing Body,Heatsin, Receptacle Clamp and so on.
