The invention relates to the technical field of HDI printed circuit board manufacturing, in particular to an HDI printed circuit board copper foil brownification device with a rolling type soft brush. The HDI printed circuit board copper foil brownification device with the rolling type soft brush comprises a brownification tank (1), an agent storage tank (2) and a prepared liquid transferring tank (3), wherein the agent storage tank (2) and the prepared liquid transferring tank (3) are connected with a prepared liquid transferring tank (9), and a rolling type soft brush mechanism is arranged in the brownification tank (1) and comprises a rotary shaft (12), the soft brush (13), a horizontal conveying device (11) and a movable guide rail (16) with a support. According to the HDI printed circuit board copper foil brownification device with the rolling type soft brush, copper foil corrosion is enhanced effectively during copper foil brownification through the liquid-phase mass transfer reinforcement, achieved by rotating the brush, of brownification treating fluid on the surface of copper foil, the liquid-phase mass transfer condition of the reaction of an organic film on the surface of the copper foil is updated in time, and on the premise that the microstructure and the mechanical binding force of the brownification film are guaranteed, the corrosion reaction speed and the film forming reaction speed are increased, the efficiency during brownification production is improved, and production cost is reduced easily.
Description
technical field [0001] The invention relates to the technical field of HDI printed circuit board through-hole processing, in particular to an HDI printed circuit board copper foil browning device with a rolling soft brush. Background technique [0002] With the continuous development of consumer electronics products such as smartphones and tablet computers towards portability and miniaturization, PCBs are constantly being developed towards higher and more dense layouts. The HDI board browning process is a chemical treatment process that can satisfy the inner layer of the multi-layer board to increase the bonding force, and it can replace the traditional black oxidation (Black Oxidation) process. It has the same final performance as the black oxidation process, which enhances the bonding force between the film layer and the prepreg, and blocks the attack on the copper surface by the amines produced by the polymerization and hardening of the epoxy resin during the pressing pro...
