- Patent Document 1 JP-A-9 130050
- Patent Document 2 JP 2002-47594
- FIG. As shown in (C), a deep dent sometimes remained in the center of via hole 60.
- the ratio was sometimes formed by all the no-holes, but it was more powerful to form a part. Filled vias with deep dents are not suitable for stacked vias that stack vias on the upper layer or conductor circuits on the upper layer, so the electrical characteristics deteriorate or the circuit breaks, resulting in electrical connectivity.
- the front and back electrical connection is performed by forming a plating film.
- a plating film is formed by electrolytic plating.
- the plating solution in the through hole may become uneven, or the plating film may stop growing and there may be a portion where the plating film is not formed. For this reason, the circuit in the through hole is deformed due to the uneven thickness of the plating film, which is not the desired shape of the plating film to be formed. In some cases, electrical connectivity may be reduced due to damage.
- the present invention has been made to solve the above-described problems, and the purpose of the present invention is to easily form a substantially flat filled via in forming a filled via and a through hole. It is to propose a plating apparatus and a plating method that can be used.
- the substantially flat filled via mentioned here means that the electrical connection reliability after the heat cycle test (-55 degrees X 5 minutes 125 degrees X 5 minutes 1000 times) even in a stacked via structure in which vias are formed on the vias. ) Trouble level of wrinkles (The rate of resistance change relative to the resistance value before the heat cycle test is (Within 10%).
- these can also be used as a plating apparatus and a plating method for forming a film in a hole in order to fill a concave portion with respect to covering.
- the present invention relates to a plating method and a plating apparatus for performing electrolytic plating while moving an insulator with respect to a coating surface in which the insulator is brought into contact with or partially in contact with the coating surface.
- the object to be covered has only been immersed in the solution. For this reason, it is impossible to eliminate liquid flow variations and irregularly generated bubbles during the formation of the plating film. As a result, it was difficult to make the plating film uniform, especially the growth of the plating film around the via hole. Also, the promotion of plating deposition in the recesses deteriorated due to changes in the plating solution composition and accumulation of impurities. As a result, filled vias with deep dents were sometimes created. This tendency tended to increase when the via hole diameter was small (150 ⁇ m or less) or when the gap between via holes was a gorgeous pitch.
- the insulator is brought into contact with or partially in contact with the surface to be covered, so that the growth of the plating film is slowed or stopped at the contacted part.
- the plating film grows in the portion where the insulator does not contact. For this reason, the plating power of the opened portions such as via holes and through holes grows.
- the conductor circuit which is a conductor portion other than the via holes does not become too thick. In other words, plating in via holes and through-holes is a force that can be reliably formed.
- the liquid flow of the plating solution can be made constant.
- the plating solution is sent to a via hole or a through hole that is being formed depending on the type of insulator, the moving condition of the insulator, the composition of the plating solution, and the plating condition.
- the plating solution is forcibly supplied to the via hole or the through hole, and the contact of the plating solution with the surface to be covered increases, so that the growth of the plating film is not hindered.
- these insulators are preferably moved along the surface to be covered.
- the insulator may be moved in the vertical and horizontal directions of the substrate with respect to the surface to be plated, or the insulator may be moved in a non-vertical and horizontal direction (for example, an oblique direction).
- move the mating surface It is possible to move the insulator relative to each other.
- the desired result can be obtained by adjusting the moving speed of the insulator, the size of the insulator, the contact ratio of the insulator to the surface to be fitted, and the like.
- the moving speed of the insulator is preferably 1.0 to 8, OmZmin. Below 1.0 mZmin, the liquid flow cannot be changed, and the result may be the same as not using an insulator. 8. If OmZmin is exceeded, the liquid flow may not be changed because the moving speed of the insulator increases. Therefore, it will be inferior to the result obtained by moving. If the moving speed is between 5.0 and 7. OmZmin, which is the most desired range, the liquid flow cannot be changed locally. When manufacturing printed wiring boards, there is an area that is not a product on the outer periphery of the product area (product area). The moving speed here is the moving speed of the insulator in the product area.
- the size of the insulator 20 in the width direction (X2) is 1: 0.9 when the length in the width direction (XI) of the substrate 30 that is a body to be attached is 1.
- ⁇ 1: 1.5 is desirable. If it is less than 0.9, the effect of the insulator does not reach both ends, so the result may be the same as when the insulator is not used. 1. If the value exceeds 5, the supply of the plating solution to the substrate may be hindered, which may cause variations in the plating film at the via hole and through hole. It is most desirable that the ratio is 1.0 to 1.2. This is because the plating film is less likely to vary.
- the size of the insulator 20 in the moving direction (Y2) is 1: 0.2 or more, assuming that the length in the height direction (Y1) of the substrate 30 that is the body to be attached is 1. Is desirable. Since the moving direction (Y2) is the size of the insulator 20, the size of the insulator 20 does not have a significant effect on the fitting quality. However, if it is less than 0.2, the load applied to the board becomes too large and the quality of the fitting is lowered. From.
- the contact ratio of the insulator is preferably 1: 0.25 to 1: 1 when the size of the substrate is 1. If the contact ratio is less than 0.25, the effect of the insulator does not reach both ends, and the result may be the same as when the insulator is not used. It is most desirable that the contact ratio is 1: 0.5 to 1: 1. This is because the plating film is less likely to vary.
- the contact ratio means that, when a porous resin (sponge) having an uneven surface is used as an insulator, a pressure is applied and a convex portion is pressed. Protruding contact area and total area (convex Part contact area + non-contact area of the recess). Similarly, as shown in FIG.
- the contact pressure of the insulator is such that when a porous resin (sponge) is used as an insulator as shown in FIG. 14 (A), or the brush is an insulator as shown in FIG. 14 (B).
- a porous resin sponge
- the ceramic is used as the insulator, desired be pressed to apply a pressure of about 30gZcm 2,.
- the insulator it is desirable to use one selected from long fibers, porous materials, and fibrous materials.
- Metal can be formed on the entire surface to be covered. After forming a metal film on the entire surface, a desired circuit pattern (conductor circuit) can be formed by etching or the like.
- Via holes or through holes can be formed by electrolytic plating.
- a resist by using a resist, a desired circuit pattern can be formed in the resist non-formation portion.
- a resin brush can be used as the long fiber constituting the insulator. In this case, the hair tip is brought into contact with the covering surface.
- the resin brush PP, PVC (vinyl chloride), + PTFE (tetrafluoroethylene), etc., which is resistant to plating chemicals, can be used.
- rosin and rubber may be used.
- porous material constituting the insulator a porous ceramic such as SiC, a porous resin such as sponge or PE (polyethylene) can be used.
- porous resin it is possible to use, for example, a polyimide film in which a micropore is formed by applying tension to the polyimide film.
- a resin fiber such as a vinyl chloride woven fabric or a non-woven fabric as a fiber constituting the insulator.
- the insulator it is also preferable to slide the insulator with respect to the surface to be covered.
- the plating solution can be circulated evenly by the plating forming portion such as via hole, and a substantially flat filled via can be formed.
- the plating apparatus 10 includes a plating tank 12 filled with a plating solution 14, a circulation device 16 for circulating the plating solution 14, and a porous resin (sponge) that contacts the plating surface on the surface side of the printed wiring board 30.
- a metal layer 52 is formed on the interlayer insulating layer 50, a plating resist 54 is formed on the metal layer 52 (see FIG. 11A), and then electrolysis is performed by electrolytic plating with the plating apparatus 10 shown in FIG. Thickening the adhesive film 56 shows the state of the film (see Fig. 11 (B) and (C))
- Example 1-1-1 when the electrolytic plating film 56 gradually increases in thickness, the insulator 20 is brought into contact with or partially in contact with the surface to be covered, so that the contacted part is not Electrolysis The growth of the attached film 56 is slowed or the growth of the plating film is stopped. On the other hand, in the portion where the insulator 20 does not contact, the electrolytic plating film 56 grows, and when the insulator 20 contacts the insulator, the precipitation of the plating is stopped or suppressed. Thus, a filled via 60 having a substantially flat surface can be easily manufactured.
- the plating circuit at the opening of the via hole has a growing force.
- the conductor circuit 58 which is a conductor portion other than the via hole does not become too thick.
- the staking in the via hole is a force that is reliably formed.
- the conductor circuit by the plating method and the staking apparatus of the prior art that does not use the insulator 20.
- a plating film having a relatively small thickness compared to the thickness can be formed.
- a conductor circuit having a higher density than the conventional one can be formed.
- a conductor circuit can be formed at a fine pitch, which is advantageous for increasing the density.
- the insulator 20 having a porous resin (sponge) force can make the liquid flow of the plating solution, particularly the liquid flow around the via hole, in a certain direction. For this reason, variations in plating film formation around the via hole can be eliminated. Therefore, in the case of forming a via hole, it is difficult to form a recess in the via hole.
- FIG. 11 (D) shows a conductive circuit connected to the lower conductive circuit 34 and the via hole 60 after the resist 54 is peeled off and the metal film 52 is removed by etching after the electrolytic plating film 56 is formed.
- FIG. 11 (E) is a sketch enlarging the portion of the electrolytic plating film 56 indicated by a circle D in FIG. 11 (D).
- FIG. 15B is an enlarged sketch of the portion of the electrolytic plating film 56 indicated by a circle F in the prior art filled via 60 (FIG. 15A) formed without using the insulator 20.
