Background technique

When the through hole of the printed circuit board is subjected to chemical copper deposition, the board to be manufactured is vertically inserted into the hanging basket and fixed, and then the flying bus sends the hanging basket into the sinking copper tank for chemical copper sinking. Among them, the existing hanging basket The structure of the basket is shown in Figure 1, including: a frame 1, a base 2, an upper bar 3, and a side bar 4 with multiple "V"-shaped grooves, so that when the board to be made is placed, the side bar 4 The "V" shaped groove on the top makes the board be placed perpendicular to the base, and is fixed by the upper bar 3.

With the development of the printed circuit board industry, a large number of plated through-holes with high thickness-to-diameter ratio appear in the design of printed circuit boards. Due to the small diameter of the through-holes and the large thickness of the board, when using the current hanging basket for electroless copper deposition, it is usually The bubbles in the hole are often difficult to get rid of in time before the copper sinking process, resulting in poor copper sinking in the through hole. In addition, during the copper sinking process, the liquid exchange inside and outside the through hole is also very slow, resulting in extremely thin or no chemical copper layer in the through hole, which can easily cause the electrical performance of the printed circuit board to fail.

In addition, hanging baskets are also required in other manufacturing processes that use chemical liquid to soak through holes, such as: cleaning through holes, browning and blackening before secondary or multiple laminations, etc. For the same reason as above, it is difficult to remove the air bubbles in the through holes in time during the processing, and it is difficult to achieve the desired effect.

The hanging basket frame 1 is a square with a hook on the top, and the size of the square is determined according to the size of the printed circuit board to be produced and the number of printed circuit boards processed in each batch. The length of the quadrilateral is generally greater than or equal to the length of the printed circuit board to be produced, and the height of the quadrilateral is greater than the height of the printed circuit board to be produced. For the convenience of loading and unloading of the printed circuit board to be produced, the height of the quadrilateral is preferably 1.1-2 times the height of the printed circuit board to be produced. In the hanging basket of this embodiment as shown in FIG. 2 , the length of the square is equal to the length of the printed circuit board to be produced, and the height of the square is 1.2 times the height of the printed circuit board to be produced. The hanging basket frame 1 has: an upper stop bar 12, a lower stop bar 13, a left stop bar 18, and a right stop bar 19 defining a first side plane; The blocking rod 21 and the right blocking rod 22, wherein the second side plane is opposite to the first side plane.

The grooved base 2 includes continuous grooves, discontinuous grooves, or both continuous grooves and discontinuous grooves, as shown in FIG. 3 and FIG. 4 . Moreover, the shape of the groove includes: V-shape, U-shape, or both V-shape and U-shape. In the hanging basket shown in Fig. 2, the grooved base 2 is a "V" shaped grooved base.

The base 2 is fixed on the bottom of the hanging basket frame 1, wherein each groove on the base 2 accommodates at most one edge of a printed circuit board, that is, the width of each groove on the base 2 is greater than the thickness of the board and at the same time smaller than the thickness of the board. 2 times the thickness of the piece. In this way, through the "V" shaped groove on the base 2, the printed circuit boards to be produced can be separated, and a printed circuit board can be placed in each "V" shaped groove in turn, or, in the set several Correspondingly place a printed circuit board in the V"-shaped groove, for example: a printed circuit board can be placed in every set number of grooves (the number of intervals can be the same or different), or arbitrarily select several grooves corresponding to Place a printed circuit board.

The first side plane of the hanging basket frame 1 includes a first guide rail 11, and the first guide rail 11 is immovably or movably installed between the upper stop bar 12 and the lower stop bar 13 of the first side plane. The angle between the guide rail 11 and the base 2 is arbitrary, preferably, the first guide rail 11 is perpendicular to the base 2 . In this way, the first guide rail 11 can guide the clip bar 3 to move up and down or back and forth, that is, the clip bar 3 can move up and down along the first guide rail 11 , and can also move back and forth against the first guide rail 11 .

Moreover, the first guide rail 11 can be at any position on the first side plane, preferably, the first guide rail 11 is located at a position corresponding to the center of the length of the printed circuit board. As shown in FIG. 2 , the first guide rail 11 is located in the middle of the first side plane and is perpendicular to the base 2 .

Each groove on the clip bar 3 can also accommodate an edge of a printed circuit board at most, that is, the width of each groove on the clip bar 3 is greater than the thickness of the board, and at the same time less than 2 times the thickness of the board.
