Definitions
- the present invention relates to a three-dimensional circuit board.
- circuit boards have achieved miniaturization of electronic devices by reducing the distance between circuit patterns, that is, the pitch to the limit, in accordance with the needs of so-called light, thin, and small fields, thereby realizing miniaturization of electronic devices, and saving resources and energy
- a circuit pattern is formed on both the front and back surfaces of the circuit board, and a conductor layer of a through hole for electrically connecting the circuit patterns is formed.
- drilling of this through hole has been done by mechanical work using a drill.
- the through hole has been formed at the same time as the circuit board by injection molding.
- Patent Document 1 JP-A-61-239694
- Patent Document 2 JP-A-63-128181
- Patent Document 3 U.S. Patent No. 4424095
- FIGS. 5 to 7. The circuit patterns 21, 31,. 41, 41 are formed, and a through-hole 51 is formed to electrically connect the circuit patterns on both sides, and the diameter of this through-hole is on the order of several tens of microns.
- a cylindrical pin for through-hole molding is used for the mold, and the diameter of this pin is on the order of tens of microns, for example, 30-50 microns. I have.
- the inner diameter of the circular through-hole 51 is the same straight shape, and the ratio of the thickness of the circuit board 21 to the inner diameter of the through-hole 51, the so-called aspect ratio, is limited to about 5 times. If it is less than 5 times, the force that enables the deposition of electroless plating. If it exceeds 5 times, the deposition of the electroless plating is difficult or impossible.
- the pitch of the circuit patterns 31 on the circuit board is reduced, so that the inner diameter of the through hole 51 must be as small as several tens of microns as described above. I can't get it.
- the aspect ratio is high, when molding a circuit board with a molding die, the mold, especially the pin for through-hole molding, cannot withstand the resistance to liquid injection flow, and accidents often occur that cause breakage. As a result, the aspect ratio is increased, and a problem occurs that the deposition does not exceed the deposition limit of electroless plating.
- a problem to be solved by the present invention is that a three-dimensional circuit board capable of preventing breakage of a molding pin of a mold, ensuring plating deposition, and thereby narrowing a circuit pitch to the limit. Is to provide.
- a first feature of the three-dimensional circuit board according to the present invention is that a predetermined circuit pattern made of a conductive material is formed on both the front and back surfaces of the circuit board made of an insulating material.
- the conductor layer of the through-hole for electrically conducting the through-hole is formed, and the shape of the through-hole is that it is long in the circuit extending direction narrowing in the direction between adjacent circuit patterns.
- the shape in which the through-hole also exposes the circuit pattern force is that it is long in the circuit extending direction narrowing in the direction between adjacent circuit patterns, and examples thereof include a rectangle and an ellipse.
- a second feature is that the through hole has a shape tapered shape in a cross section in the thickness direction of the circuit board.
- This tapered shape means that the through hole is tapered in the direction between the adjacent circuit patterns and further expanded in the circuit extending direction of the circuit pattern, or in the direction between the circuit patterns or the circuit extending direction.
- the opening is tapered in one of the directions.
- a third feature is that a partition is formed on a circuit board between circuit patterns. This is because, as described above, since the circuit pitch is formed to be extremely narrow, paste-type solder is used when, for example, lead terminals are soldered and mounted on this circuit pattern. There is a danger of short-circuiting between adjacent circuit patterns due to splashing, and this partition is to prevent this scattering.
- a fourth feature is that the through-hole is a blind through-hole that fills the inside of the through-hole.
- the effect of the present invention is to prevent breakage of a mold, especially a molding pin, and to ensure deposition of plating, thereby making it possible to narrow the circuit pitch to the limit. Furthermore, it is possible to prevent the solder from scattering at the time of mounting, thereby preventing a short circuit. In particular, if the through-holes are blind through-holes, the flux cleaning step at the time of solder mounting can be omitted and the outflow of solder can be prevented, so that the reliability of the three-dimensional circuit is further improved.
- FIG. 1 A plan view of a circuit board
- FIG.2 Enlarged sectional view taken along line a-a in Fig. 1.
- FIG. 8 is a plan view showing another embodiment.
- FIG. 10 is a bottom view in another embodiment.
- the structure of the three-dimensional circuit board 1 according to the present invention will be described with reference to FIGS. 1 to 3.
- the surface of the circuit board 2 made of an insulating material has a conductive material force as shown in FIG.
- the predetermined circuit patterns 3, 3,... Are formed, and the predetermined circuit patterns 4, 4,.
- the inner surface shape of the through holes 5, 5,... Is long in the direction between the adjacent circuit patterns 3, 3, that is, in the circuit extending direction narrowing in the left-right direction in FIG. 1, that is, in the vertical direction in FIG. is there.
- the shape of the lower end opening 5c as well as the upper end opening 5b of this through hole is not a force, but the circuit extending direction narrows in the direction between the adjacent circuit patterns 4, that is, the horizontal direction in FIG. Long in the vertical direction. That is, it has a rectangular shape.
- the shape of the through hole 5 is not limited to a rectangular shape, but may be an elliptical shape that is long in the vertical direction. For this reason, a pin for forming the through hole 5 having such a shape can be used with a diameter larger than that of the conventional pin, and the risk of breakage of the pin is reduced.
- the cross section of the circuit board 2 in the thickness direction expands from the open end 5b on the front surface of the through holes 5, 5,. It is tapered. Therefore, the opening end 5c opening in the circuit pattern 4 on the back surface of the circuit board 2 is approximately twice as large as the opening end 5b on the front surface, as is clear when comparing FIG. 1 and FIG. Has become. At the same time, the width of the circuit pattern 4 on the back surface of the circuit board 2 is about twice as large as the width of the circuit pattern 3 on the front surface.
- the tapered shape of the through hole 5 refers to the direction between the circuits with the adjacent circuit patterns 3, 3,..., 4, 4,.
- the shape has a tapered shape that expands in the circuit extending direction of the circuit patterns 3 and 4 that are not only in the left-right direction of 3, but in both the vertical direction of FIGS.
- the shape is not limited to such a shape that is expanded in both directions, and is not limited to any one of the directions between adjacent circuit patterns 3, 3 It may be a tapered shape that is widened toward.
- the aspect ratio may be For example, even if it becomes 10 times, it is practically about 5 times, so that the catalyst solution or the electroless solution smoothly circulates and flows in the through holes, and ensures catalyst deposition and plating deposition.
- the through-hole forming pin itself can also be formed in a trapezoidal cross section, so that the risk of breakage is significantly reduced.
- the pitch of the circuit patterns 3 and 4 has been extremely narrowly reduced to near the limit.
- this solder since there is a risk that the paste-like solder may scatter and short-circuit between adjacent circuit patterns, a partition 6 is formed between the circuit patterns to prevent the scatter.
- FIGS. Fig. 4 (A) shows a primary molded product 20 formed by injecting a plating grade liquid crystal polymer into the cavity with the mold closed, and the external shape of the primary molded product is the circuit board 2 which is the final product.
- the liquid crystal polymer an aromatic polyester is used.
- FIG. 4 (B) the surface of the primary molded product 20 becomes a surface 20a roughened by chemical etching.
- the etching treatment is performed, for example, by heating an aqueous alkaline solution in which ionic soda or ionic potassium is dissolved at a predetermined concentration to a predetermined temperature and immersing the primary molded article 20 for a predetermined time. Thereafter, the primary molded product 20 is inserted into the mold again. At this time, in the mold, a cavity having a shape having a predetermined gap is formed on the outer periphery of the primary molded article 20. In a state where the mold is closed, an axylene alkyl group-containing polyvinyl alcohol-based material is used as a masking agent.
- a resin for example, “Ekomati AX” (trade name of Nippon Synthetic Chemical Industry Co., Ltd.)
- a catalyst 8 made of palladium, gold, or the like is applied to the roughened surface 20a of the secondary molded product 200.
- This catalyst is applied by a known method.
- the secondary molded article 200 is immersed in a mixed catalyst solution of silver and noradium, and then activated with an acid such as hydrochloric acid or sulfuric acid to deposit palladium on the surface.
- a relatively strong reducing agent such as stannous tin is adsorbed on the surface and immersed in a catalyst solution containing a noble metal ion such as gold.
- a catalyst solution containing a noble metal ion such as gold.
- the through holes 5 are tapered as described above. Therefore, the catalyst solution circulates smoothly and gold is reliably deposited on the surface.
- the secondary molded article 200 is heated in hot water to elute the portion of the mask 7 formed by the secondary molding into the hot water. This means that if the secondary molded product 200 is placed in hot water at 80 ° C for 10 minutes, “Ekomati AX” will be completely eluted in the hot water. Therefore, as shown in FIG.
- circuit patterns 3 and 4 are formed by attaching the catalyst-applied portion.
- the through holes 5 are tapered as described above, Since the electroless solution smoothly circulates and flows in the hole, plating can be reliably formed.
- chemical copper plating or chemical nickel plating is used for this plating.
- the step of forming a conductive circuit by heat treatment to remove moisture inside is completed, and the three-dimensional circuit board 1 is completed.
- an electronic element is solder-mounted on one circuit pattern, for example, the upper circuit pattern 3, and the circuit pattern 4 on the opposite side is used as a contact in this method. Flux and soldering power during soldering Pass through the through hole 5 and flow out to the contact surface of the circuit pattern 4, which may hinder the function as a contact.
- the through-hole 5 is filled with the plating 30, and the inside of the filled plating has a cone-like hollow shape.
- the lower end of the attachment is a circuit pattern 40 on the lower surface.
- Other configurations are the same as those of the above-described embodiment, and are denoted by the same reference numerals. Therefore, according to this embodiment, the flux cleaning step at the time of solder mounting can be omitted, and the outflow of solder can be prevented, so that the reliability of the three-dimensional circuit is further improved.
- the present invention can be used as a connector for connecting a foldable portion between a circuit portion of a foldable mobile phone and a liquid crystal display surface via a coaxial cable.
