Abstract

The invention discloses an electroless copper plating device with a cleaning unit. The device includes a pedestal. An electroless copper plating tank is fixed to the middle of the top of the pedestal.A first mounting cylinder is fixed to one side of the top of the pedestal, and the inner bottom of the first mounting cylinder is provided with a drive motor. The output shaft of the drive motor is fixed to a screw rod through a coupler. A servo motor is mounted inside a motor base, and the output shaft of the servo motor is fixed to a connection block. Two ends of the connection block are fixedto push-rod motors. One end of each push-rod motor, far from the connection block, is fixed to a vertical rod. The insides of the vertical rods are provided with mounting cavities. Electric heating tubes are mounted in the mounting cavities. One side of each vertical rod, far from the connection block, is fixed to an arc-shaped plate. The bottom of each push-rod motor is fixed to a lifting and descending device. The lower end of each lifting and descending device is fixed to a winding roller. Two guiding wheels are symmetrically fixed to the inner bottom of the electroless copper plating tank.The electroless copper plating device is unique in structure, ingenious in design, reasonable in structure, convenient to clean and suitable for promotion.

Description

technical field [0001] The invention relates to the technical field of copper plating, in particular to an electroless copper plating equipment with a cleaning device. Background technique [0002] Electroless copper plating is a process in circuit board manufacturing, usually also called copper sinking or porosity (PTH), which is an autocatalytic redox reaction. First, it is treated with an activator to make a layer of active particles adsorb on the surface of the insulating substrate. Usually, metal palladium particles are used (palladium is a very expensive metal, and the price is high and has been rising. In order to reduce costs, there are practical colloids abroad. Copper process is running), copper ions are first reduced on these active metal palladium particles, and these reduced metal copper crystal nuclei themselves become the catalytic layer of copper ions, so that the reduction reaction of copper continues in these new copper crystals on the nuclear surface. El...
