Description

Technical Field

[0001] This utility model belongs to the field of semiconductor integrated circuit manufacturing technology and relates to a substrate for testing adhesive removal rate. Background Technology

[0002] Integrated circuit (IC) substrates are widely used in various electronic devices. They are high-end products with significant technical challenges in the printed circuit board (PCB) industry, serving as the carrier for connecting and transmitting signals between bare chips and the PCB, providing protection and support, and forming heat dissipation channels. IC substrates are characterized by high density, high precision, high performance, miniaturization, and thinness, making them a key component in semiconductor packaging. Therefore, they have become an indispensable part of various electronic devices, with demand increasing daily and a very broad development prospect.

[0003] IC substrates have high performance requirements and are very demanding in terms of raw material selection. Conventional PCBs use flame retardant grade 4 (FR4) material, but the performance of FR4 material is far from meeting the performance requirements of IC substrates.

[0004] Currently, most IC substrates use bismaleimide and triazine (BT) material, which features high durability, low expansion, and ease of processing. However, BT material is relatively hard and has a high TG (thermal charge), resulting in a large amount of adhesive residue inside the holes after mechanical or laser drilling. Conventional chemical desmearing methods are insufficient to completely remove this residue; therefore, plasma desmearing is performed before the initial chemical desmearing process.

[0005] The advantages of Plasma descaling are mainly as follows: (1) High efficiency and environmental protection: Plasma descaling does not require the use of organic solvents, thus it is more environmentally friendly; (2) Strong adaptability: Plasma descaling can be used for products of different sizes and thicknesses; (3) Precise control: By controlling energy and time, the descaling rate can be precisely controlled; (4) Surface activation: Plasma treatment can form an active layer on the material surface, enhancing the adhesion, compatibility, and wettability of the material. However, Plasma treatment requires precise control of energy and time. Improper operation may result in insufficient or excessive descaling of the product. The setting of parameters such as energy and time for Plasma needs to be adjusted by adjusting the descaling rate. Different types of materials have different Plasma descaling capabilities, so it is necessary to set matching Plasma parameters for each material. At the same time, it is also necessary to monitor and adjust the descaling uniformity of the Plasma equipment every day.

[0006] Therefore, how to provide a degumming rate test carrier to improve the accuracy and efficiency of test results, achieve traceability of degumming rate test, and effectively improve the uniformity of degumming has become an important problem that needs to be solved by those skilled in the art.

[0007] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this application and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this application.

[0064] Please see Figure 1 The diagram shows a structural schematic of a test vehicle, including a base plate 102 and a slot 102. The slot 102 is formed on the base plate 102. When performing a descaling rate test, a descaling rate plate 104 needs to be fixed to the slot. Please refer to [link to relevant documentation]. Figure 2 There are two ways to fix it:

[0065] (1) Place the adhesive removal rate sheet 104 at the slot 102 of the vehicle, and attach the upper and lower edges of the adhesive removal rate sheet 104 to the base plate 102 of the vehicle using a 10mm wide high-temperature resistant tape 103.

[0066] (2) First, drill four first fixing holes 105 and second fixing holes 106 with a diameter of 1.0 mm on the outside of the four corners of the adhesive removal rate plate 104 and the carrier slot 102, respectively. Then, use fixing wires 107 to pass through the first fixing holes 105 and the second fixing holes 106 to fix the adhesive removal rate plate 104 to the carrier slot 102.

[0067] However, in the above two solutions, the first solution requires additional fixing tape 103 to be pasted on the upper and lower edges of the adhesive removal rate sheet 104, and the second solution requires additional fixing holes to be drilled on the adhesive removal rate sheet 104 and the carrier base plate 102. Both solutions are inconvenient to operate, resulting in low testing efficiency.

[0068] In addition, please see Figure 1 The test vehicle has nine slots 102, which cannot correspond one-to-one with the adhesive removal rate plate 104. That is, the adhesive removal rate plate 104 cannot record the amount of adhesive removed at each position, making the test process untraceable. As a result, it is impossible to determine the position with poor adhesive removal uniformity and to adjust the adhesive removal uniformity in a targeted manner.

[0069] Therefore, this utility model provides a degumming rate testing carrier, which can improve the accuracy of test results and facilitate operation to improve testing efficiency by adding fixing components and traceability codes. At the same time, it can also realize the traceability of degumming rate testing and effectively improve the uniformity of degumming.

[0070] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0071] It should be emphasized that the term "including / comprises" as used herein refers to the presence of a feature, whole, step, or component, but does not exclude the presence or addition of one or more other features, wholes, steps, or components.

[0072] Features described and / or illustrated for one embodiment may be used in the same or similar manner in one or more other embodiments, combined with features in other embodiments, or substituted for features in other embodiments.

[0073] In the detailed description of the embodiments of this utility model, for ease of explanation, the schematic diagrams illustrating the device structure may be partially enlarged without adhering to the general scale, and the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. Furthermore, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0076] It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of the present invention. Therefore, the illustrations only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0077] This utility model provides a descaling rate testing carrier. Please refer to [link / reference]. Figure 3 The diagram shows the structure of the adhesive removal rate testing carrier of this utility model, including an adhesive removal rate plate 201, a carrier base plate 202, a fixing component, and a traceability code. The carrier base plate 202 has a carrier slot 203, and the fixing component is symmetrically arranged on both sides of the carrier slot 203. The traceability code includes a first traceability code 204 and a second traceability code 205 that correspond to each other. The first traceability code 204 is disposed on the carrier base plate 202 and located above the carrier slot 203, and the second traceability code 205 is disposed on the adhesive removal rate plate 201.

[0078] For details, please refer to Figure 4Each of the aforementioned fixing components includes an L-shaped intermediate pad 206, a surface cover 207, and a fixing screw 208. The L-shaped intermediate pad 206 is located between the vehicle base plate 202 and the surface cover 207, and the thickness of the L-shaped intermediate cover is greater than the thickness of the adhesive removal rate plate 201. The fixing screw 208 passes through the surface cover 207 and the L-shaped intermediate pad 206 and is threadedly connected to the vehicle base plate 202. The thickness of the L-shaped intermediate cover is greater than the thickness of the adhesive removal rate plate 201 to ensure that the adhesive removal rate plate 201 can be inserted into the fixing component. At the same time, there is a gap between the adhesive removal rate plate 201 and the vehicle base plate 202 and the surface cover 207, so that the edge of the adhesive removal rate plate 201 and the area where the vehicle base plate 202 and the surface cover 207 overlap will also be subject to Plasma adhesive removal without affecting the Plasma adhesive removal effect.

[0079] For details, please refer to Figure 5 The L-shaped intermediate pad 206 includes a vertical portion 2061 and a horizontal portion 2062. Part of the horizontal portion 2062 is located below the carrier slot 203. The length L1 of the vertical portion 2061 is 66mm, the width W1 of the vertical portion 2061 is 8mm, the length L2 of the horizontal portion 2062 is 2mm, and the width W2 of the horizontal portion 2062 is 2mm.

[0080] For details, please refer to Figure 6 The carrier base plate 202, the L-shaped intermediate pad 206, and the surface cover plate 207 on both sides of the carrier slot 203 together form a slot space. When the adhesive removal rate test carrier is working, the adhesive removal rate piece 201 only needs to be inserted into the corresponding slot 203, making it more convenient and flexible to pick up and put in the adhesive removal rate piece 201, thereby improving the efficiency of the test. The first traceability code 204 uses No.1-No.9, and the second traceability code 205 uses 1-9. When inserting the adhesive removal rate piece 201, the insertion position can be determined by the corresponding first traceability code 204 and second traceability code 205. Specifically, for example, if the second traceability code 205 on the adhesive removal rate piece 201 is 1, then the adhesive removal rate piece 201 is inserted into the carrier slot 203 where the traceability code is No.1. Therefore, after the test is completed, the test process can be traced through the first traceability code 204 and the second traceability code 205, so as to accurately determine the location of uneven glue removal, thereby allowing targeted adjustments to areas with problems in glue removal rate and improving the uniformity of glue removal.

[0081] It should be noted that the traceability code markings must all use green lasers. This is because green lasers are cold light sources, unlike conventional mechanical drilling and CO2 laser drilling. They do not generate a lot of heat, which can prevent a large amount of glue residue from being generated in the marking area, thereby avoiding affecting the test results of the amount of glue removed.

[0082] As an example, the thickness T2 of the L-shaped intermediate pad 206 ranges from 0.1mm to 10mm, and the thickness of the adhesive removal rate sheet 201 ranges from 0.4mm to 1.5mm. In this embodiment, the thickness T2 of the L-shaped intermediate pad 206 is 2mm, and the thickness of the adhesive removal rate sheet 201 is 1mm.

[0083] As an example, the thickness T1 of the vehicle base plate 202 ranges from 0.1mm to 10mm, and the thickness T3 of the surface cover plate 207 ranges from 0.1mm to 10mm. In this embodiment, the thickness T1 of the vehicle base plate 202 is 2mm, the thickness T2 of the L-shaped intermediate pad plate 206 is 2mm, and the thickness T3 of the surface cover plate 207 is 2mm.

[0084] For example, please refer to [link / reference]. Figure 3 The number of vehicle slots 203 is multiple, and a pair of fixing components are symmetrically arranged on both sides of each vehicle slot 203. In this embodiment, the number of vehicle slots 203 is nine. In other embodiments, the number of vehicle slots 203 can also be other suitable numbers, which can be determined according to the specific situation. No further restrictions are imposed here.

[0085] As an example, each of the fixing components has a plurality of fixing screws 208, and the plurality of fixing screws 208 are arranged at intervals along the long side of the surface cover plate 207. In this embodiment, each of the fixing components has two fixing screws 208.

[0086] As an example, the fixing screw 208 is a hexagonal screw.

[0087] As an example, the length L3 of the vehicle base plate 202 ranges from 200mm to 700mm, and the width W3 of the vehicle base plate 202 ranges from 200mm to 700mm. In this embodiment, the length L3 of the vehicle base plate 202 is 516mm, and the width W3 of the vehicle base plate 202 is 415mm. In other embodiments, the length L3 and width W3 of the vehicle base plate 202 can be other suitable values. For example, the length L3 of the vehicle base plate 202 is 200mm, 300mm, 400mm, or 700mm, and the width W3 of the vehicle base plate 202 is 200mm, 300mm, 400mm, or 700mm. No further restrictions are imposed here.

[0088] For example, please refer to [link / reference]. Figure 6 The length L4 of the carrier slot 203 is greater than the length L5 of the adhesive removal rate sheet 201, and the width W4 of the carrier slot 203 is less than the width W5 of the adhesive removal rate sheet 201.

[0089] As an example, the length L4 of the carrier slot 203 ranges from 10mm to 150mm, and the width W4 of the carrier slot 203 ranges from 10mm to 150mm. In this embodiment, the length L4 of the carrier slot 203 is 70mm, the width W4 of the carrier slot 203 is 66mm, the length L5 of the adhesive removal rate sheet 201 is 69mm, and the width W5 of the adhesive removal rate sheet 201 is 69mm.

[0090] As an example, the length L6 of the surface cover 207 is 66mm, and the width W6 of the surface cover 207 is 10mm.

[0091] As an example, a first through hole (not shown in the figure) is provided in the surface cover plate 207, and a second through hole 209 is provided in the vertical portion 2061 of the L-shaped intermediate pad plate 206 (see [reference]). Figure 5 The central axes of the first through hole and the second through hole 209 coincide with each other, so that the fixing screw 208 is threadedly connected to the carrier base plate 202 through the first through hole and the second through hole 209.

[0092] As an example, the diameter of the first via is in the range of 0.1mm to 5mm, and the diameter of the second via 209 is in the range of 0.1mm to 5mm.

[0093] For example, please refer to Figure 7 The length L7 of the first traceability code 204 ranges from 2mm to 20mm, and the width W7 of the first traceability code 204 ranges from 2mm to 20mm. The length of the second traceability code 205 ranges from 2mm to 20mm, and the width of the second traceability code 205 ranges from 2mm to 20mm. In this embodiment, the length L7 of the first traceability code 204 is 20mm, the width W7 of the first traceability code 204 is 10mm, the length of the second traceability code 205 is 5mm, and the width of the second traceability code 205 is 10mm.

[0094] This utility model also provides a method for preparing a descaling rate test carrier, comprising the following steps:

[0095] S1: First, manufacture the vehicle base plate 202.

[0096] Specifically, the vehicle base plate 202 has dimensions of 516mm × 415mm and a thickness of 2mm. Nine vehicle slots 203 are evenly distributed on the vehicle base plate 202, and the dimensions of the vehicle slots 203 are 66mm × 70mm.

[0097] S2: Use a green laser to burn out the first traceability code 204: No.1-No.9 at the upper center of the slot 203 on the carrier. Similarly, use a green laser to burn out the corresponding second traceability code 205: 1-9 in the upper right corner area of ​​the adhesive removal rate sheet 201.

[0098] As an example, the font size of the first traceability code 204 is 20mm × 10mm.

[0099] S3: Form the L-shaped intermediate pad 206, and drill two second through holes 209 with a diameter of 1.0 mm in the vertical part 2061 of the L-shaped intermediate pad 206.

[0100] As an example, the thickness of the L-shaped intermediate pad 206 is 2mm, the length of the vertical portion 2061 of the L-shaped intermediate pad 206 is 66mm, the width of the vertical portion 2061 of the L-shaped intermediate pad 206 is 8mm, the length of the horizontal portion 2062 of the L-shaped intermediate pad 206 is 2mm, and the width of the horizontal portion 2062 of the L-shaped intermediate pad 206 is 2mm.

[0101] S4: A layer of the surface cover plate 207 is superimposed on the L-shaped intermediate pad plate 206, and two first through holes with a diameter of 1.0 mm are drilled in the surface cover plate 207.

[0102] As an example, the surface cover 207 has a thickness of 2 mm, a length of 66 mm, and a width of 10 mm.

[0103] S5: Use the fixing screws 208 to fix the vehicle base plate 202, the L-shaped intermediate pad 206 and the surface cover plate 207 together.

[0104] As an example, the fixing screw 208 is a hexagonal screw with a length of 6mm, and there are a total of four fixing screws 208 on both sides of each of the vehicle slots 203.

[0105] Through the above steps S1 to S5, the adhesive removal rate test carrier can be manufactured. The size of the adhesive removal rate sheet 201 is still 69mm × 69mm, and the thickness of the adhesive removal rate sheet 201 is 0.4mm to 1.5mm. When using the adhesive removal rate test carrier, the adhesive removal rate sheet 201 can be directly inserted into the slots on both sides of the slot 203 of the carrier after preparation. Neither tape nor fixing strap is used for fixation. At the same time, there is a gap between the adhesive removal rate sheet 201 and the carrier base plate 202 and the surface cover plate 207, so that the edge of the adhesive removal rate sheet 201 and the area where the carrier base plate 202 and the surface cover plate 207 overlap will also be subject to Plasma adhesive removal without affecting the Plasma adhesive removal effect.

[0106] In summary, the adhesive removal rate testing carrier of this utility model includes an adhesive removal rate plate, a carrier base plate, fixing components, and traceability codes. The carrier base plate has a carrier slot, and the fixing components are symmetrically arranged on both sides of the slot. Each fixing component includes an L-shaped intermediate pad, a surface cover plate, and fixing screws. The L-shaped intermediate pad is located between the carrier base plate and the surface cover plate, and its thickness is greater than that of the adhesive removal rate plate. The fixing screws penetrate the surface cover plate and the L-shaped intermediate pad and are threadedly connected to the carrier base plate. The traceability codes include a first traceability code and a second traceability code, which are corresponding to each other. The first traceability code is located on the carrier base plate above the carrier slot, and the second traceability code is located on the adhesive removal rate plate. This adhesive removal rate testing carrier improves the accuracy of test results, facilitates operation to improve testing efficiency, and enables traceability of the adhesive removal rate test, effectively improving the uniformity of adhesive removal. Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0107] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
