Description

Technical Field

[0001] The invention relates to the technical field of copper-clad laminates, and in particular to a glass fiber bundle twisting method, a device, a glass fiber cloth and a printed circuit board. Background Art

[0002] Printed circuit boards are widely used in electronic equipment. The core material of printed circuit boards is copper clad boards. The glass fiber cloth in copper clad boards plays a role in strengthening and providing specific electrical properties. Figure 1 As shown, a copper clad laminate is shown as an example, wherein copper foil 101 and copper foil 103 serve to connect signals, resin 102 serves to bond copper foil 101 and copper foil 103, and glass fiber cloth 104 serves two functions in the copper clad laminate: (1) to provide reinforcement to the copper clad laminate to prevent deformation of the printed circuit board processed by the copper clad laminate. Deformation of the printed circuit board may cause components assembled on the printed circuit board to fall off, thereby damaging the electronic equipment. Glass fiber cloth provides specific structural strength. (2) When high-speed signals are transmitted in the copper foil, electromagnetic waves are generated around the copper foil, which hinder the transmission of high-speed signals. This characteristic that hinders signal transmission is DK (dielectric constant) and DF (dielectric loss factor) in the parameters of the copper clad laminate. Another function of the glass fiber cloth is to provide specific DK and DF. Copper foil 101, copper foil 103, resin 102 and glass fiber cloth 104 jointly affect signal transmission. According to the percentage determined by the degree of influence, the influence of glass fiber cloth 104 on signal transmission accounts for about 60%.

[0003] As signal rates become higher and higher, the requirements for electrical performance strength and structural strength are also gradually increasing. In related technologies, the method of forming glass fiber bundles used cannot meet the relevant electrical performance requirements or structural strength requirements, and thus cannot meet the needs of electronic equipment.

[0020] This embodiment provides a method for twisting glass fiber bundles. Figure 2 As shown, the method comprises the following steps: S201. Obtain data of various glass fiber materials.

[0021] Specifically, obtaining data on a variety of different glass fiber materials refers to obtaining relevant data on glass fibers suitable for copper clad laminates, including DK, DF, Young's modulus and tensile strength of each material. As shown in Table 1, several common materials, including E glass fiber, S glass fiber, M glass fiber, D glass fiber and Q glass fiber, are shown as examples.

[0022] Table 1

[0023] S202. Based on the requirements and data of the electronic equipment, determine the types and proportions of several glass fiber materials to be selected.

[0024] Specifically, the requirements of electronic equipment include: electrical performance and structural strength. Based on electrical performance, the requirements may include: first degree, second degree, and fourth degree, wherein the fourth degree is higher than the second degree, and the second degree is higher than the first degree. Based on structural strength, the requirements may include: no requirement, third degree, and fifth degree, wherein the fifth degree is higher than the third degree.

[0025] Specifically, based on the requirements and data of electronic equipment, determining the types and proportions of several selected glass fiber materials means determining the types and proportions of selected glass fiber materials based on the requirements of the electronic equipment for electrical performance and structural strength using the acquired data, thereby providing a basis for subsequent twisting and forming glass fiber bundles.

[0026] S203, forming a glass fiber bundle by twisting based on the type and proportion.

[0027] Specifically, forming a glass fiber bundle based on the type and proportion by a twisting method means that after the type and proportion of the glass fiber material are determined, a plurality of glass fiber filaments are twisted into a glass fiber bundle by a twisting method.

[0028] The present invention provides a glass fiber bundle twisting method, device, glass fiber cloth, and printed circuit board. The method obtains data of glass fiber materials, responds to the needs of electronic equipment, determines the type and proportion of selected glass fiber materials, and forms glass fiber bundles by twisting. In this process, the glass fiber bundle is formed by mixing multiple glass fiber materials according to certain types and proportions, and on this basis, the different needs of electronic equipment are met, so that the twisting scheme of the glass fiber bundle meets the relevant electrical performance requirements or structural strength requirements.

[0029] In an optional embodiment, the requirements of the electronic device include: electrical performance, based on the requirements of the electronic device and data, the types and proportions of several glass fiber materials selected are determined, including: In response to the electrical performance reaching a first level, a first type combination of selected glass fiber materials is determined based on data; and a first proportion of the selected glass fiber materials is determined based on a first preset correspondence between the first level, the first type combination and a first proportion of each glass fiber material.

[0030] Specifically, the requirements for electronic equipment include electrical performance, which means that only electrical performance needs to be considered without considering structural strength, or there are certain requirements for electrical performance but the demand for structural strength is not obvious, that is, the electrical performance needs to reach the first level.

[0031] Specifically, in response to the electrical performance needing to reach a first level, based on the data, determining the first type combination of glass fiber materials to be selected means using the acquired data to determine the type combination of glass fiber materials that is consistent with the electrical performance reaching the first level. Taking the data shown in Table 1 as an example, two of E glass fiber, D glass fiber or Q glass fiber are usually selected for combination, and the determination is made based on the first level of electrical performance that needs to be reached. For example, when higher electrical performance is required, more Q glass fiber needs to be added.

[0032] Specifically, based on the first preset correspondence between the first degree, the first type combination and the first ratio of each glass fiber material, determining the first ratio of the selected glass fiber material means, based on the first preset correspondence, after determining the first degree and the first type of the selected glass fiber, determining the ratio of each glass fiber. Similarly, taking the data shown in Table 1 as an example, the first type combination can be a combination of two of E glass fiber, D glass fiber or Q glass fiber, and the first ratio can be 40%, 60%; 50%, 50% or other ratios, and a typical ratio is 50% E glass fiber and 50% D glass fiber or 50% E glass fiber and 50% Q glass fiber, such as Figure 3 As shown, 301 represents E glass fiber, and 302 represents D glass fiber or Q glass fiber.

[0033] In an optional embodiment, a glass fiber bundle is formed by twisting based on the type and ratio, including: Based on the first type combination and the first ratio, at least two glass fiber materials corresponding to the first type combination and the first ratio are twisted together to form a glass fiber bundle.

[0034] Specifically, based on the first type combination and the first ratio, at least two glass fiber materials corresponding to the first type combination and the first ratio are mixed and twisted to form a glass fiber bundle, which means twisting a determined type of glass fiber material in a determined ratio to form a glass fiber bundle of a mixed twisting scheme, forming a glass fiber bundle such as Figure 3 Fiberglass bundles shown.

[0035] In an optional embodiment, the requirements of the electronic device include: electrical performance and structural strength. Based on the requirements and data of the electronic device, the types and proportions of several glass fiber materials to be selected are determined, including: In response to the electrical performance needing to reach a second level and the structural strength needing to reach a third level, a second type combination of selected glass fiber materials is determined based on the data; based on a second preset correspondence between the second level, the third level, the second type combination and the second ratio of each glass fiber material, a second ratio of the selected glass fiber material is determined, wherein the second level is higher than the first level.

[0036] Specifically, the requirements for electronic equipment include electrical performance and structural strength, which means that the requirements for electrical performance and structural strength are basically equal, that is, the electrical performance needs to reach the second level and the structural strength needs to reach the third level, which is equivalent to requiring certain electrical performance and certain structural strength at the same time.

[0037] Specifically, in response to the electrical performance reaching the second level and the structural strength reaching the third level, based on the data, determining the second type combination of the selected glass fiber materials means using the acquired data to determine the type combination of glass fiber materials that is consistent with the electrical performance reaching the first level and the structural strength reaching the third level. Taking the data shown in Table 1 as an example, three types of E glass fiber, S glass fiber or M glass fiber, and Q glass fiber are usually selected for combination, and the determination is made based on the second level of electrical performance and the third level of structural strength. For example, when higher electrical performance is required, more Q glass fiber needs to be added, and when more structural strength is required, more S glass fiber or M glass fiber needs to be added.

[0038] Specifically, based on the second preset correspondence between the second degree, the third degree, the second type combination and the second ratio of each glass fiber material, determining the second ratio of the selected glass fiber material means determining the ratio of each glass fiber after determining the second degree, the third degree and the second type combination of the selected glass fiber based on the second preset correspondence. Similarly, taking the data shown in Table 1 as an example, the first type can be a combination of three of E glass fiber, S glass fiber or M glass fiber, and Q glass fiber, and the second ratio can be 40%, 30%, 30%; 50%, 25%, 25% or other ratios, and a typical ratio is 40% E glass fiber, 30% D glass fiber, and 30% Q glass fiber, such as Figure 4 As shown, 401 represents E glass fiber, 402 represents D glass fiber, and 403 represents Q glass fiber.

[0039] In an optional embodiment, a glass fiber bundle is formed by twisting based on the type and ratio, including: Based on the second type and the second ratio, at least two glass fiber materials corresponding to the second type and the second ratio are twisted together to form a glass fiber bundle.

[0040] Specifically, based on the second type combination and the second ratio, at least two glass fiber materials corresponding to the second type combination and the second ratio are mixed and twisted to form a glass fiber bundle, which means twisting a determined type of glass fiber material in a determined ratio to form a glass fiber bundle of a mixed twisting scheme, forming a glass fiber bundle such as Figure 4 Fiberglass bundles shown.

[0041] In an optional embodiment, the requirements of the electronic device include: electrical performance and structural strength. Based on the requirements and data of the electronic device, the types and proportions of several glass fiber materials to be selected are determined, including: In response to the electrical performance needing to reach a fourth level and the structural strength needing to reach a fifth level, based on the data, a third type combination of glass fiber materials is determined; based on the data, a twisting position corresponding to each glass fiber material combined with the third type is determined; based on the twisting position, a third proportion of the selected glass fiber materials is determined, wherein the fourth level is higher than the second level, and the fifth level is higher than the third level.

[0042] Specifically, the requirements for electronic equipment include electrical performance and structural strength, which means that the requirements for electrical performance and structural strength are both high, that is, the electrical performance needs to reach the fourth level and the structural strength needs to reach the fifth level, which is equivalent to requiring better electrical performance and greater structural strength.

[0043] Specifically, in response to the electrical performance reaching the fourth level and the structural strength reaching the fifth level, based on the data, determining the third type combination of the selected glass fiber materials refers to using the acquired data to determine the type combination of glass fiber materials that are consistent with the electrical performance reaching the fourth level and the structural strength reaching the fifth level. Taking the data shown in Table 1 as an example, Q glass fiber, D glass fiber, and S glass fiber are usually selected for combination, determined according to the fourth level of electrical performance and the fifth level of structural strength, and arranged in a certain layout.

[0044] In an optional embodiment, when two glass fiber materials are used, based on the third type combination, the third ratio and the corresponding twisting position of each glass fiber material, at least two glass fiber materials corresponding to the third type combination and the third ratio are twisted to form a glass fiber bundle, including: placing a glass fiber material with high structural strength inside and a glass fiber material with high electrical properties outside, and twisting two glass fiber materials corresponding to the third type combination and the third ratio to form a glass fiber bundle.

[0045] In a further optional embodiment, when more than three glass fiber materials are used, based on the third type combination, the third ratio and the corresponding twisting position of each glass fiber material, at least two glass fiber materials corresponding to the third type combination and the third ratio are twisted to form a glass fiber bundle, including: twisting more than three glass fiber materials corresponding to the third type combination and the third ratio to form a glass fiber bundle in a manner that the structural strength of the glass fiber material increases from the outside to the inside and the electrical properties of the glass fiber material increase from the inside to the outside.

[0046] Specifically, since better electrical performance and greater structural strength are required in this case, combined with the characteristics of the glass fiber cloth in the printed circuit board, that is, the copper foil is distributed on the upper and lower sides of the glass fiber cloth, the material with better electrical performance is distributed on the periphery of the glass fiber bundle, which is closest to the copper foil for signal transmission, to ensure better electrical performance; while inside the glass fiber bundle, it is far away from the copper foil and surrounded by the other two glass fiber materials, which will not affect the electrical performance, while its own high-strength characteristics can be brought into play; in the middle of the glass fiber bundle, a third glass fiber material is distributed, and because it is farther away from the copper foil than the glass fiber material on the outside, it has less impact on the electrical performance, but can also play a role in improving the electrical performance. Therefore, based on the data, determining the twisting position corresponding to each glass fiber material of the third type means determining, based on the data, the material with the best electrical properties, the material with the highest structural strength, and the material with electrical properties in between the two in each third type of glass fiber material, thereby determining that the twisting position corresponding to the material with the best electrical properties is the periphery of the glass fiber bundle, surrounding the other two glass fiber materials; the twisting position corresponding to the material with the highest structural strength is the inside of the glass fiber bundle, surrounded by the other two glass fiber materials; the twisting position corresponding to the material with electrical properties in between the two is the middle of the glass fiber bundle, sandwiched by the other two glass fiber materials, forming a Figure 5 Fiberglass bundles shown.

[0047] Specifically, determining the third ratio of the selected glass fiber materials based on the twisting position means wrapping each glass fiber material layer by layer from the inside to the outside based on the determined twisting position to determine the third ratio of the selected glass fiber materials. Figure 5 As shown, 501 represents Q glass fiber, 502 represents D glass fiber, and 503 represents S glass fiber.

[0048] In an optional embodiment, a glass fiber bundle is formed by twisting based on the type and ratio, including: Based on the third type combination, the third ratio and the corresponding twisting position of each glass fiber material, at least two glass fiber materials corresponding to the third type combination and the third ratio are twisted to form a glass fiber bundle.

[0049] Specifically, based on the third type combination, the third ratio and the corresponding twisting position of each glass fiber material, at least two glass fiber materials corresponding to the third type combination and the third ratio are twisted to form a glass fiber bundle, which means twisting the determined type of glass fiber material at the corresponding twisting position in a determined ratio to form a glass fiber bundle of the twisting scheme, forming the glass fiber bundle as shown in FIG. Figure 5 Fiberglass bundles shown.
