Description
Technical Field
The present invention relates to a plating tank bottom box of vertical continuous plating equipment capable of improving plating performance.
Background
As PCBs continue to evolve toward lighter, thinner, shorter, smaller, higher density, the compatibility and capability of electroplating devices are all presenting greater challenges. VCP (vertical continuous plating equipment) has long-term research on the uniformity of a hard board, and with the rapid development of a flexible screen of a mobile phone and the like, a soft board is more and more shown with excellent characteristics, but the electroplating uniformity result of the soft board is not ideal so far. The thinnest thickness of the soft board can reach 36 micrometers, namely the thickness of copper on the board surface is 12 micrometers, and the thickness of the middle base material is 12 micrometers. The flexible board with a thinner thickness is easily disturbed by the liquid spraying under the liquid spraying effect of VCP, the copper thickness at the bottom is seriously uneven under the influence of the edge effect, and the risks of board folding or board clamping and the like can be caused by serious people. Therefore, the electroplating equipment and the electroplating process need to be optimized to meet the requirements of the production of electroplating plates with different sizes: the uniformity of hard board electroplating can be realized, and the uniformity problem of soft board electroplating can be solved.
The structure of the existing vertical continuous electroplating equipment is characterized in that an electroplating plate (cathode) is vertically suspended in a tank body and uniformly moves along the horizontal direction, and the front electroplating plate and the rear electroplating plate in the tank body continuously move.
In order to meet the production requirement, the size of the electroplating plate can be changed along with the difference of models, a U-shaped suck-back bottom box or a U-shaped shielding device corresponding to the U-shaped electroplating plate can be arranged at the bottom of the electroplating tank below the electroplating plate under the common condition, and the U-shaped suck-back bottom box or the U-shaped shielding device is used for shielding a power line generated by the bottom excess sizes of the anodes 3 at the two sides of the electroplating plate in the electroplating tank so as to prevent the bottom of the electroplating plate from being. Even if the size of the electroplating plate changes, the U-shaped suck-back bottom box needs to be ensured for shielding the electric power line below the electroplating plate. Because the bottom area is not shielded or is shielded too little in the electroplating process, the electric lines of force on the bottom are too much, the deposition of the electroplated metal ions on the bottom area is increased, and the electroplating thickness of the bottom is too thick.
As can be seen from fig. 1 and 2, the bottom box of the prior art is formed by a channel-shaped structure with a U-shaped cross section, which extends along the forward direction of the plating plate, and is used for adjusting the shielding anode 3 to shield the excessive power lines at the bottom of the plating plate. Because the electroplating clamp is adopted to suspend the electroplating plate generally, the bottom of the electroplating plate is not provided with any guide structure, for the soft plate, the design of the bottom box needs to have certain capability of ensuring the safe passing of the electroplating plate, and meanwhile, the adjustment of the electroplating uniformity needs to be considered.
The plate passing capability means that the plating bath can ensure the thickness of a plate through which the plating plate can safely pass under certain jet flow and transmission speed. Generally, the thinner the plate thickness, the better the plate passing ability. However, the current design cannot satisfy the board passing capability of the rigid board (FR4 substrate) mainly because of: the rigidity of the FR4 base material hard plate is higher, and the verticality of the plate can not be corrected by utilizing the flow field in the tank body. 2. The hard plates are provided with a deformation, the deformation of each hard plate is different, and the deformation of the longer plate is more obvious. In view of the above, there is therefore a need for a bottom-passing apparatus that can correct the verticality of a hard board. However, for the flexible printed circuit board, the bottom calibration device may cause the flexible printed circuit board to pass through the flexible printed circuit board with a certain probability of generating the card board. It is therefore desirable to be able to: if the bottom correcting plate device can be withdrawn when the plate is soft, the correcting device is required to be at a designated position when the plate is hard.

The outer vertical plate falls on the bottommost part under the action of gravity, and the maximum shielding effect is always ensured. This is because the size of the plating plate varies, and a typical shield plate is used to shield a 10-30cm area of the bottom of the plating plate. If the inner vertical plate is simply enlarged, when the size of the electroplating plate is large, the shielding plate moves downwards to interfere with the bottom of the copper groove; when the size of the plating plate is small, the shielding plate may cause the shielded area to be too large, resulting in excessive shielding.

Because the main water inlet pipeline is arranged below the water inlet pipeline, the water inlet pipeline is prevented from interfering with the pipeline.
The lower end of the groove body lifting pull rod is connected with cantilever ends transversely extending out of the outer sides of two side plates of the groove body.
The lower end of the independent bottom plate lifting pull rod is connected with cantilever ends transversely extending from two sides of the independent bottom plate, and notches are formed in two side plates of the groove body corresponding to the cantilever ends.
The horizontal roller structure is characterized in that a shaft sleeve is sleeved on a vertical bolt, a horizontal pulley is arranged on the shaft sleeve, and a rubber ring is sleeved on the pulley.
The lifting mechanism comprises a power device and a connecting device, and the connecting device is separately connected with the groove body lifting pull rod and the independent bottom plate lifting pull rod to realize lifting.

During production operation, the size of the electroplating plate is input, the bottom box is pulled by the lifting mechanism through the input size of the electroplating plate in the electric control program, and the bottom box can be lifted along with the size change of the electroplating plate.
In uniformity adjustment, the relative position of the shield plate to the plating plate generally does not need to be adjusted significantly (referred to herein as face-to-face shielding) for different sizes of plating plates under the same operating conditions. Therefore, the double shielding plates are used, namely the shielding plates are fixed on the pull rod of the bottom box through the vertical elongated holes, can move up and down along with the bottom box, and can be adjusted through the vertical elongated holes. The double shielding plates are structurally characterized in that the inner vertical plates are fixed through the long-strip-shaped holes and the bolts penetrating through the long-strip-shaped holes and screwed on the lifting pull rods of the groove body, the outer vertical plates fall on the bottommost part (the shielding part is larger than the bottom of the plate surface) under the action of gravity, and the maximum shielding effect of the bottom is always ensured.
To box at the bottom of the bilayer, box at the bottom of independent bottom plate 20, U type, two shields independently go up and down respectively, and horizontal gyro wheel 4 is fixed on independent bottom plate 20, guides the electroplate board, and box at the bottom of the U type and two shields shield the board and shield and make the electroplate board be when placing perpendicularly in the cell body at the uniform velocity motion and homogeneity adjust each other and not influence. Box still has an advantage to shielding the regulation at the bottom of the bilayer to shielding, electroplates the distance of the independent bottom plate of the bottom box of board bottom distance, and box can realize independent bottom plate, end box and two independent lift adjustment of shielding the board at the bottom of the bilayer, so adjust more portably to the homogeneity.
