- a base material based on a polyimide film or a film base material impregnated with a matrix resin using glass cloth as a reinforcing material is generally used as an interposer. Due to high rigidity requirements, high dimensional stability requirements, low thermal expansion requirements, etc. in such applications, the use of film substrates using glass cloth is increasing. However, the anisotropy in the X and Y directions of the film substrate, which is caused by the difference in the structure between the warp and weft directions of the glass cloth, has been viewed as a problem. At the same time, the need for thinner packages makes it necessary to reduce the thickness of the interposer itself, and to reduce the thickness of the glass cloth used from 50 ⁇ to 20 ⁇ .
- the invention described in Japanese Patent Application Laid-Open No. 8-18179 is intended to improve solder heat resistance, and does not describe an effect on anisotropy in the X and Y directions. Further, the invention described in Japanese Patent Application Laid-Open No. 111-149656 is intended to prevent the resin from being perforated at the time of preparing the pre-preda, and has an effect on the anisotropy in the XY direction. There is no description.
- the invention described in Japanese Patent Application Laid-Open No. 2002-38365 includes a statement suggesting that the opening rate in the XY direction is increased and the anisotropy in the XY direction is reduced.
- the examples described in Tables 1 to 4 it was possible to sufficiently reduce the anisotropy in the XY direction. Absent.
- the examples include a description of a multilayer board composed of four layers of pre-preda. There is no description about the film substrate of the layer.
- An object of the present invention is to provide a thin glass cloth for a printed wiring board having excellent mechanical properties such as excellent isotropy and dimensional stability, and a film substrate using the glass cloth. It is in.
- the present inventors have made the warp yarn and the weft yarn of the glass cloth the same type of glass yarn, and the cross-sectional shape and shape of the warp yarn and the weft yarn ⁇ ⁇ ⁇
- the anisotropy in the XY direction of the film substrate using the glass cloth is greatly improved, and the average diameter and the number of single yarns constituting the yarn used are reduced.
- a film base material using the glass cloth has excellent isotropy and is thin as in the case of a film consisting only of a luster. Reached.
- the present invention is as follows.
- the ratio of the warp yarn width to the weft yarn width is 0.80 or more and 1.20 or less.
- the load was applied in the warp direction to the elongation in the weft direction.
- the glass cloth as described in 1 above which can be produced by flattening the glass cloth at a tension of 49 NZm or less per lm width of the glass cloth.
- a film base comprising one glass cloth described in any one of the above 1 to 4 and a matrix resin.
- FIG. 1 is a graph showing the results of measuring the elongation in the horizontal direction and the elongation in the vertical direction with respect to the load of a 2116 type glass cloth as an example of a glass cloth woven by the conventional technique.
- the same type of glass yarn means a yarn having the same type of glass such as E glass, the average single yarn diameter and the number of strands constituting the strand, and the same number of strands constituting the yarn.
- the tension of the warp yarn under tension tends to be smaller than the weft of the weft yarn.
- the warp yarn density is set to a high density such that the gap between adjacent warp yarns is substantially zero, the warp of the warp yarn may be larger.
- the cross-sectional shape of the warp yarn and the weft yarn are made equal, and the spun state of each yarn is made equal. If possible, it is considered that the anisotropy of the film base using the glass cloth can be reduced.
- the “cross-sectional shape” here refers to the width and thickness of the yarns that compose the glass cloth. This can be measured by embedding the yarn in an epoxy resin or the like and observing the cross section of the yarn cut out by cutting with an electron microscope. When the same type of glass yarn is used, if the yarn width increases due to processing or the like, the yarn thickness will decrease.Therefore, regarding the anisotropy in the XY direction, the cross-sectional shape can be represented by the yarn width. it can. In order to reduce the anisotropy of the film substrate using the glass cloth, the ratio of the warp yarn width to the weft yarn width constituting the glass cloth is preferably not less than 0.80 and not more than 1.20. Is preferably 0.90 or more and 1.10 or less.
- the glass cloth since the glass cloth has a woven structure, it has a characteristic that it is stretched in one direction of tension in the XY plane.
- the elongation is correlated with the amount of lip of the constituting yarn, and when the lip is large, the elongation with respect to the tension is also large.
- the stiffness of the yarn in a direction perpendicular to the direction also affects the elongation with respect to the tension in that direction (transition of the crimp).
- the lip of the constituting yarn has a great effect. Therefore, the swelling state of the entire glass cloth can be evaluated by the elongation percentage in the vertical direction and the elongation percentage in the horizontal direction with respect to the tension.
- the elongation rate with respect to the above-mentioned tension is evaluated by applying the method described in the section of 7.4 Tensile Strength of the JISR340 glass fiber general test method.
- a test piece with a diameter of about 30 mm and a length of about 250 mm is taken from the warp yarn direction and the weft yarn direction of the woven fabric, and two grip portions having a width of 25 mm are taken.
- the test piece is held at two points, and the test piece is pulled at about 200 mm / min and the load at break is determined.

- the test piece is set to a width of 35 mm
- the length is set to 1885 mni.
- the rate of increase in the gap between the grips when a load is applied ((interval under load minus interval under no load) / None The elongation was determined from the distance X 100 during loading. Fig.
- the weft of the glass cloth in order to reduce the anisotropy of the film base material using the glass cloth, the weft of the glass cloth must be set so that the load per 25 mm is in the range of 25 to 10 ON.
- the ratio of the elongation in the warp direction when the load is applied in the warp yarn direction to the elongation in the warp direction when a load is applied in the warp direction is 0.80 or more and 1.20 or less. Is preferably 0.90 or more and 1.10 or less, more preferably 0.95 or more and 1.05 or less.
- the thickness of the glass cloth is thin, but if it is made thinner than a certain extent, it is not possible to achieve the required properties in terms of strength. Specifically, the thickness is preferably from 10 to 50 ⁇ m, more preferably from 15 to 30 ⁇ m.
- the average single yarn diameter is preferably from 3.0 ⁇ m to less than 6.0 ⁇ m, more preferably from 3.0 ⁇ m to less than 5.0 ⁇ m.
- the smaller the single yarn distribution of the yarn bundle in the Z direction the thinner the yarn. For this purpose, a state in which the yarn bundle is sufficiently widened is preferable.
- the number of single yarns in the yarn bundle is small in order to reduce the distribution of single yarns in the Z direction and sufficiently widen the state.However, in order to handle glass yarns, the number of single yarns should be at least 5 °. is necessary. Therefore, in order for the yarn bundle to be sufficiently widened to form a thin cloth, the number of glass yarns is preferably 204 or less and 50 or more, more preferably 100 or less and 50 or more. The above is more preferable. Also, in order to be used as a glass cloth, it is important to have a glass cloth structure without bending and misalignment. Therefore, it is preferable that the yarns constituting the glass cloth have adjacent yarns in the same direction arranged as closely as possible.
- the “sufficiently widened glass thread” means a glass thread in which the intervals between adjacent threads are arranged as closely as possible.
- the twist number of the glass thread is 0.5. It is preferable to reduce the number of twists to less than the number of turns / inch, preferably 0.3 to 0 times.
- the yarn width can be easily expanded and the thickness of the glass cloth can be reduced. Further, since the yarn is flattened and the cross-sectional shape of the yarn itself approaches the shape of a flat plate from an elliptical shape, the distribution of glass fibers in the glass cloth can be made more uniform.
- fiber opening by water pressure, fiber opening by high-frequency vibration using a liquid medium, continuous ultrasonic processing, and pressurization by a roll are applied to the yarns constituting the glass cloth. It is preferable to perform flattening. By performing the flattening process, the yarn width is increased, and it becomes easy to form a structure in which adjacent yarns of both the warp yarn and the weft yarn are practically arranged without gaps. Further, since the yarn is flattened and the cross-sectional shape of the yarn itself approaches the shape of a flat plate from the elliptical shape, the distribution of the glass fibers in the glass cloth can be made more uniform, as in the case of the low twist yarn described above.
- Spraying is a fiber-spreading process that is performed using a high-pressure water spray that is sprayed from a nozzle having a divergent angle.
- the nozzles used for spray processing are roughly divided into fan nozzles, uniform fan nozzles, filled cone nozzles, and empty cone nozzles. The widening of the filaments and weaving intersections in the yarn bundle is achieved by fan nozzles or uniform fan nozzles. Is preferred.
- a filled conical nozzle is used, the amount of water injected into the glass cloth is significantly different between the area directly below the nozzle and the end of the sprinkling flow, so the glass cloth is misaligned by the high-pressure water concentrated just below the nozzle. May occur.
- an empty conical nozzle is used, the impact force on the amount of injected water is significantly lower than that of a sector nozzle, so the efficiency of flattening is reduced.
- a nozzle having a divergence angle in the range of 10 ° to 150 ° is preferable, but a nozzle having a divergence angle in the range of 50 ° to 110 ° is more preferable.
- nozzles with a divergence angle of less than S10 ° the degree of divergence of the filament and weave intersection in the yarn bundle is small, and for nozzles with a tangent greater than 150 °, the distance from the center of the nozzle to the end of the sprinkling flow is extremely long. Therefore, the impact force when the water stream collides with the glass cloth is significantly different between the center of the nozzle and the end of the sprinkling flow.
- Nozzles used for spray processing are preferably arranged in a staircase arrangement such as a staggered arrangement, an irregular staggered arrangement, or a combination of a staggered arrangement and an arrangement inclined at a fixed angle.

- the arrangement pitch of the nozzles is appropriately adjusted according to the spread width of the high-pressure water spray, the distance from the nozzle to the glass cloth, the degree of overlap between the adjacent high-pressure water sprays, and the like.
- the columnar flow process is a fiber opening process performed by columnar flow high-pressure water jetted from a group of nozzles having pores with a diameter of 0.1 to 0.5 mm.
- the nozzles used for columnar flow machining are preferably linear nozzles and plate nozzles, each of which is individually arranged in large numbers.
- a large number of nozzles having pores can be arranged. If these nozzles are arranged in a single row, it becomes difficult to uniformly inject the columnar high-pressure water over the entire surface of the glass cloth.Therefore, the nozzle groups should be shifted in the width direction over multiple rows. Is preferred. Further, it is preferable that the nozzle group itself be swung or circularly moved in order to prevent the impact force of the jet water from being localized on the glass cloth.
- NZ cm 2 ⁇ 100 ON / cm 2 is preferred, 5 ON / cm ⁇ 800 More preferably NZc m 2, most preferably Rere is 50 N / cm 2 ⁇ 500 N / cm 2. If the pressure of the water used during the flattening process is less than 10 NZ cm 2, the effect of widening the yarn bundle and the weaving intersection of the glass cloth cannot be obtained, and if V is larger than 1000 N / cm 2 , The weave of the warp yarn and the weft yarn constituting the glass cloth may shift due to the widening force.
- processing is performed by applying ultrasonic waves to the glass cloth through the medium using an ultrasonic vibrator that vibrates at a specific frequency. Is preferably performed.
- the medium transmitting the ultrasonic wave can be appropriately selected within a range in which the effect of the flattening process is achieved, and is preferably water, an organic solvent such as alcohol, or water in which an organic solvent is dispersed.
- the frequency of the ultrasonic transducer is preferably 10 to 100 kHz, more preferably 15 to 70 kHz, and most preferably 20 to 50 kHz. When the frequency is less than 10 kHz, the uniformity of the widened state is poor, and when the frequency is higher than 100 kHz, the widened state is low.
- the output of the ultrasonic oscillator for driving the ultrasonic vibrator is 20 to 5000 W, preferably 100 to 1500 W, and more preferably 200 to 1000 W.
- An example of such an apparatus is an ultrasonic oscillator manufactured by Phoenix Series manufactured by Riki Ijo Corporation.
- both the glass cloth and the ultrasonic vibrator are immersed in a tank containing a liquid, and the ultrasonic vibrator is used by the ultrasonic oscillator.
- the glass cloth is flattened by generating ultrasonic waves from the glass cloth.
- the transmission of ultrasonic waves to the glass cloth in this opening process is not performed through direct contact between the glass cloth and the ultrasonic vibrator, but through the medium. It is preferable to arrange them so that they do not touch each other.
- the distance between the glass cloth and the ultrasonic vibrator is preferably in the range of 1 to 30 cm, more preferably in the range of 1 to 10 cm.
- the distance between the glass cloth and the ultrasonic vibrator is less than 1 cm, the processing state of the glass cloth may be locally deformed, resulting in poor appearance. If the distance is larger than 30 cm, the loss until the energy of the ultrasonic vibrator is transmitted to the glass cloth increases.
- the distance between the ultrasonic transducer and the ultrasonic transducer be determined in consideration of conditions such as the type of glass cloth, the type of liquid, the frequency of the ultrasonic transducer, the output of the ultrasonic oscillator, and the direction of ultrasonic transmission.
- the number of the ultrasonic vibrator may be one or plural.
- the above-described fiber-spreading process using a liquid as a medium by high-frequency vibration can be performed by either a continuous method or a patch method.
- a continuous method for example, a method is adopted in which an ultrasonic vibrator is fixed in a tank filled with a liquid, and a glass cloth is run so as to pass through the tank.
- the traveling speed of the glass cloth is appropriately set within a range in which the processing effect of the present invention is achieved, and is preferably 0.1 to 100 mZmin.
- the arrangement of the ultrasonic vibrator and the glass cloth is usually set so that the width direction of the vibrator is perpendicular to the running direction of the glass cloth, but it is set so that it forms an angle of several tens of degrees. Is also good.
- the time required for immersing the glass cloth in the liquid and performing fiber opening processing is appropriately set under conditions within a range in which the effects of the present invention can be achieved, but is preferably about 0.01 to 30 seconds.
- the tension applied to the glass cloth for transport should be 49 N / m (5 kg /) or less per 1 m width of the glass cloth. And more preferably 2 ON / m (2 kg / m) or less.
- a tension detection method using a tension detector generally used in the film field.
- this tension detection method two guide rolls (hereinafter, referred to as guide roll 1 and guide roll 2) and one tension detection roll are arranged at the apexes of an isosceles triangle so as to be bilaterally symmetrical. So that passes through guide roll 1, tension detection roll, and guide roll 2 in this order.
- the tension detecting roll the resultant force of the tension acting on the guide roll 1 side, the tension acting on the guide roll 2 side, and the gravity acting on the tension detecting roll acts as a load on the tension detecting roll downward.
- the tension applied to the glass cloth can be obtained by calculation from the measurement value of the load sensor set under the mouth.
- the above-described tension detector constantly monitors the tension in the warp yarn direction and transports the glass cloth before and after the equipment that performs the flattening process.
- a method of controlling the rotation speed of the drive roll arranged for the above by a tension control device can be preferably used. When the tension detected by the tension detector is higher than the set value, the tension control device sets the rotation of the front drive roll in the traveling direction to be slow and the rotation of the rear drive roll to be fast, and the detection is performed.
- the tension in the warp yarn direction is controlled by setting the rotation of the front drive roll in the traveling direction to be faster and the rotation of the rear drive roll to be slower. It is.
- a flattening force under lower tension instead of a commonly used roll-type transfer device, for example, Japanese Patent Application Laid-Open No. 11-507995 discloses A horizontal conveyor type transfer device can be preferably used.
- Japanese Patent Application Laid-Open No. 2002-38367 discloses a method of spreading under low tension.
- the spreading rate of the warp yarn to the weft yarn described in the examples (spreading ratio ⁇ yarn width) X100 / (25 / density).) From the calculation of the ratio of the warp yarn width to the weft yarn width, only 0.59 to 0.67 was obtained. This value is insufficient to eliminate the anisotropy in the XY direction, which is the object of the present invention.
- the ratio of the average width of the warp yarn to the average width of the weft yarn is 0.80.
- a glass cloth of 1.20 or less can be obtained. Since the specific tension value is not described in JP-A-2002-38367, the cause of such a difference is not clear, but in the invention described in JP-A-2002-38367, the roll type is not opened. It is presumed that the fiber conveyor was used and the tension on the glass cloth could not be reduced as much as the horizontal conveyor type described above.
- the flattened glass cloth is dried with an infrared heater, hot air dryer, or the like. Drying conditions are preferably at 100 to 200 ° C. for about 10 seconds to 2 minutes. If the tension applied to the yarn during drying is large, the glass yarn that has been sufficiently widened by the flattening process described above may return due to the tension, and therefore, under the same tension conditions as the flattening process. Drying is preferably performed.
- the glass cloth wound on the roll removes the binder, glue, etc. applied to the surface by high-temperature desizing. Thereafter, in order to increase the adhesion to the matrix resin to be impregnated, a silane coupling agent is preferably applied and dried. Furthermore, as a usual surface treatment of glass cloth, a treatment to harden the texture of the glass cloth, for example, to increase the amount of adhesion, to use a treatment agent with a high coating property, or to use a silane cup generally used as a treatment agent By increasing the degree of polycondensation of the silanol groups of the ring agent, or by carrying out a treatment having a glass yarn filling effect, the handleability of glass cloth is improved.
- Matrix resins used include epoxy resins, unsaturated polyester resins, polyimide resins, bismaleidotriazine resins, thermosetting resins such as cyanate resins, polyphenylene oxide resins, polyetherimide resins, and fluorine resins. And the like, or a resin mixture thereof. Further, a resin in which an inorganic filler such as aluminum hydroxide or talc is mixed in the resin may be used. However, for the purpose of the present invention, the matrix resin is preferably a resin having excellent flexibility.
- the physical properties of the glass cloth in the examples and the comparative examples, the method of preparing a laminated board using the glass cloth, and the test method were measured by the following methods.
- the measurement was performed according to JIS R 324.
- the elongation at the time of applying a load was measured according to the above-mentioned method which applied JISR340.
- the glass cloth is embedded in cold-cured epoxy, polished to cut out the glass thread cross section, and the warp and weft threads are measured with an electron microscope (S-570, manufactured by Hitachi, Ltd.) at a magnification of 22. At 0x, each cross-sectional photograph was taken. The yarn width was measured for each of 150 warp yarns and weft yarns, and the average value was calculated as warp yarn width and weft yarn width.
- brominated bisphenol A-type epoxy resin 504 (produced by Japan Epoxy Resin Co., Ltd.) 85 parts by weight (solid), cresol nopolak epoxy resin 180 (Japan epoxy resin Co., Ltd.) 15 parts by weight (solid), N, N-dimethylformamide 12 parts by weight, methoxyethanol 12 parts by weight, dicyandiamide 2.5 parts by weight, 2-ethyl-4-methylimidazole 0 .2 parts by weight were blended to prepare an epoxy resin varnish.
