  • Circuit Board Assembly and Radio Unit Comprising the Same
    Publication number: 20240080981
    Abstract: A circuit board assembly (1), comprising a first circuit board (10) and a second circuit board (20) which are electrically connected with each other, and a monolithic substrate (30) configured for supporting a power component and comprising a first contact surface (31) that is fixedly connected to and forms a thermal contact with the second circuit board (20), the circuit board assembly being characterized in that, the substrate (30) further comprises a second contact surface (32) that is fixedly connected to the first circuit board (10) and forms a thermal contact with the first circuit board (10) so that the substrate functions as an extension of the first circuit board to support the second circuit board. A radio unit comprising a circuit board assembly (1) is also disclosed.

  • Catalytic reactor configuration, preparation and method of direct synthesis of ethylene through oxygen-free catalysis of methane
    Patent number: 10661239
    Abstract: A reactor configuration comprises an inlet section I, a preheating section II, a transition section III, a reaction section IV and an outlet section V; except for the preheating section II and the reaction section IV, the existence of the inlet section I, the transition section III and the outlet section V depends on reaction conditions; and the process realizes no coke deposition synthesis of methane and high selectivity synthesis of ethylene. The methane conversion rate is 20-90%; ethylene selectivity is 65-95%; propylene and butylene selectivity is 5-25%; aromatic hydrocarbon selectivity is 0-30%; and coke deposition is zero.
