[0002] Currently, with the rapid development of high-end electronic materials and devices such as integrated circuits, power semiconductors, flexible display modules, high-energy-density batteries, and multifunctional sensors, increasingly stringent requirements are being placed on the performance stability and reliability of sensitive materials during high-temperature processing. The preparation of sensitive materials in liquids, slurries, thin films, thick films, and polymer coatings often requires strictly controlled high-temperature thermosetting processes to achieve key processes such as crosslinking, solvent removal, structural stabilization, or functional activation. Therefore, pre-evaluation of sensitive materials is necessary to determine and adjust their properties.

[0003] Traditional high-temperature curing chambers used for laboratory thermocuring are mostly based on forced-air convection heating. Furthermore, traditional thermocuring chambers are mostly unable to perform online testing and evaluation of electrical properties, thermal properties, and optical responses during the heat treatment process, which greatly limits their application in research and development and reliability assessment.

The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0035] This application provides an online thermosetting evaluation device 100 for experimental use, mainly for online evaluation of the properties of sensitive materials, so as to facilitate the evaluation and adjustment of the performance of sensitive materials during the thermosetting process in the experimental stage. Here, sensitive materials include, but are not limited to, polyimide materials, high-purity slurries, passivation coatings, etc.

[0036] Please see Figures 1 to 8 The experimental online thermosetting evaluation device 100 includes a housing 10, a door 20, a tray 30, a controllable atmosphere mechanism 40, and an infrared heat source 50. The housing 10 has an internal cavity 11 with multiple side walls 12, one of which has a first opening 13 communicating with the interior of the cavity 11. The housing 10 also has an interface 14 communicating with the cavity 11 for gas input or output. The door 20 is mounted on the side of the housing 10 with the first opening 13 and can rotate relative to the housing 10 to open or close the first opening 13. The tray 30 is housed within the cavity 11 and is used to hold the material to be evaluated. The controllable atmosphere mechanism 40 is connected to the interface 14 and is used to control the gas content within the cavity 11. Here, the gas can be oxygen, or a special inert gas such as nitrogen or argon. Multiple infrared heat sources 50 are configured, all emitting infrared rays. Multiple sidewalls 12 surround the tray 30, each sidewall 12 having at least one infrared heat source 50, so that the heat emitted by the infrared heat sources 50 surrounds the circumference of the tray 30. It is understood that this application utilizes the infrared rays emitted by the infrared heat sources 50 to penetrate into the sensitive material, inducing molecular vibrations and chemical reactions, achieving simultaneous internal and external heating, and avoiding over-curing of the sensitive material surface due to thermal gradients. Simultaneously, the presence of at least one infrared heat source 50 on each sidewall 12 creates a three-dimensional, surrounding heating space, resulting in more uniform heating of the sensitive material and preventing localized overheating or insufficient thermal curing. Furthermore, the rapid heating rate of the infrared heat sources 50 allows the accommodating cavity 11 to quickly reach the preset temperature, improving thermal curing efficiency. Furthermore, combined with the controllable atmosphere mechanism 40, the content of various gases (oxygen, inert gas) in the accommodating cavity 11 can be varied and controlled, thereby constructing different thermosetting environments to meet specific processing needs for different sensitive material systems (such as liquids / slurries / films / chips).

[0037] It should be noted that, through the configuration of the structure in this application, the heating rate inside the accommodating cavity 11 can be ≥10℃ / min, the temperature control range is RT+15℃ to 550℃, and the temperature resolution reaches ±0.1℃.

[0038] In one embodiment, the box 10 is generally rectangular or cylindrical in shape. In this embodiment, the box 10 is rectangular.

[0039] Furthermore, the length of the enclosure 10 is defined as W, the width as D, and the height as H; wherein W, D, and H satisfy the following conditions: 900mm≤W≤1100mm, 800mm≤D≤1000mm, and 1600mm≤H≤1800mm, respectively. That is, the experimental online thermosetting evaluation device 100 provided in this application has an external dimension with a height H less than or equal to 1.8m and a width D less than or equal to 1.1m. Thus, compared to commercially available experimental infrared curing ovens (mostly fixed, large, and heavy systems), this application is compact and lightweight, making it more suitable for deployment in laboratories and pilot-scale (intermediate testing) spaces.

[0040] Preferably, the value of W can be 900mm, 950mm, 1000mm, 1050mm, 1100mm, etc.; the value of D can be 800mm, 850mm, 900mm, 950mm, 1000mm, etc.; and the value of H can be 1600mm, 1650mm, 1700mm, 1750mm, 1800mm, etc. Of course, this is not limited to these values, and the values ​​of W, D, and H can be set according to actual needs.

[0041] In one embodiment, the volume of the accommodating cavity 11 is set to A, where A satisfies: 150L ≤ A ≤ 250L. Here, the value of A can be 150L, ​​180L, 200L, 230L, 250L, etc. Of course, it is not limited to this, and the value of A can also be set according to actual needs.

[0042] Please continue reading. Figure 4 and Figure 5 Along the length direction X of the housing 10, the accommodating cavity 11 has opposing first sidewalls 111 and second sidewalls 112; along the width direction Y of the housing 10, the accommodating cavity 11 has opposing third sidewalls 113 and fourth sidewalls 114; and along the height direction Z of the housing 10, the accommodating cavity 11 has opposing fifth sidewalls 115 and sixth sidewalls 116, with the fifth sidewall 115 located below the sixth sidewall 116. A first opening 13 is formed on the third sidewall 113. Infrared heat sources 50 are provided on the first sidewall 111, second sidewall 112, fourth sidewall 114, sixth sidewall 116, and the side of the door 20 facing the interior of the accommodating cavity 11. Thus, at least five sidewalls 12 of the accommodating cavity 11 have infrared heat sources 50, meaning heat sources are present around the tray 30, as well as at the bottom or top, thereby forming multi-point, multi-angle temperature control and achieving highly uniform heating.

[0043] Preferably, an infrared heat source 50 can also be provided on the sixth side wall 116, so that each side wall 12 of the accommodating cavity 11 is provided with an infrared heat source 50, thereby allowing the tray 30 to be fully and three-dimensionally covered by the infrared heat source 50, further improving the uniformity of heating.

[0044] Here, the accommodating cavity 11 is generally rectangular. Of course, it is not limited to this; the accommodating cavity 11 can also be cylindrical, in which case at least one infrared heat source 50 is provided on the upper and lower side walls 12 of the cylinder. Four, five, or six infrared heat sources 50 can be provided on the peripheral walls of the cylinder.

[0045] Please see Figure 5 Multiple infrared heat sources 50 are configured on the side wall 12, and these multiple infrared heat sources 50 are arranged at intervals. This configuration can increase the heat generation at a single side wall 12, resulting in a higher and faster heating rate within the accommodating cavity 11.

[0046] Here, on one side wall 12, the number of infrared heat sources 50 can be set to two, three, or four. Of course, the number is not limited to this example; the number of infrared heat sources 50 can also be set according to actual needs.

[0047] Furthermore, a mounting groove 121 with a second opening is recessed on the sidewall 12, and the second opening is connected to the accommodating cavity 11; the corresponding infrared heat source 50 is installed into the corresponding mounting groove 121. In this way, the installation of the infrared heat source 50 can avoid encroaching on the space of the accommodating cavity 11, so that it has enough space to accommodate the sensitive material to be cured.

[0048] As a preferred embodiment, a reflector can be installed in the mounting slot 121 to reflect the infrared heat source 50, thereby forming a closed thermal radiation system and ensuring that the heating uniformity is controlled within ±1%.

[0049] Please see Figure 6 and Figure 7 The housing 10 is also equipped with a wire through-hole 15 and a rotating plate 16 covering the wire through-hole 15. The wire through-hole 15 is used to thread a wire harness so that the wire harness is electrically connected to an external monitoring device, thereby allowing the monitoring device to monitor the state of sensitive materials in real time during the heat treatment process. The rotating plate 16 is located at the wire through-hole 15 and is rotatably connected to the housing 10, used to cover or open the wire through-hole 15. In other words, when the wire through-hole 15 is not needed, the rotating plate 16 can be rotated to close the wire through-hole 15, thereby activating the protection function; when the wire through-hole 15 needs to be used, the rotating plate 16 can be rotated to open the wire through-hole 15.

[0050] In one embodiment, a sleeve 151 is provided in the wire through hole 15, one end of the sleeve 151 extends out of the wire through hole 15 and forms a retaining edge 152, the retaining edge 152 is attached to and fixedly connected to the surface of the housing 10; wherein, the rotating plate 16 is rotatably connected to the sleeve 151. Here, by providing the sleeve 151, the wire harness can be better led out, and at the same time, the sleeve 151 can be used to protect the wire harness.

[0051] Furthermore, the enclosure 10 is also provided with a baffle 17, which forms an accommodating space 171 with the enclosure 10. The wire hole 15 is located in the accommodating space 171, so that the wire hole 15 is shielded and protected by the baffle 17.

[0052] Preferably, the baffle 17 is detachably connected to the housing 10.

[0053] Optionally, the baffle 17 and the housing 10 can be detachably connected using threaded or snap-fit ​​fittings. It should be noted that threaded fittings can be bolts or screws, etc.

[0054] In one embodiment, the baffle 17 has flanges 172 at both ends, which are fitted to the housing 10 and connected in a detachable manner. This fitting method improves the stability of the baffle 17 during installation.

[0055] like Figure 7 As shown, interface 14 is located within the accommodating space 171. Thus, interface 14 can also be shielded and protected by the baffle 17. Additionally, a rotating plate 16 can be provided at interface 14, allowing it to be shielded when not in use.

[0056] Please continue reading. Figure 1 The door 20 and the body 10 are connected by a hinge. Furthermore, a sealing ring is provided at the door 20 and / or the first opening 13. When the door 20 rotates relative to the body 10 and closes the first opening 13, the door 20 and the body 10 are sealed together by the sealing ring, thereby preventing heat loss from the accommodating cavity 11 through the first opening 13.

[0057] Furthermore, a latch can be provided on the door 20. When the door 20 is closed, it can be locked to the box body 10 by the latch, thereby preventing the first opening 13 from being passively opened due to factors such as the pressure inside the internal accommodating cavity 11 or accidental operation by external personnel, which would affect the quality of sensitive material evaluation.

[0058] Here, the latch 21 can be an electronic lock or a mechanical lock.

[0059] Please see Figures 5 to 7The controllable atmosphere mechanism 40 is mainly used through interface 14 to control the flow rate of nitrogen, argon or special inert gas into the accommodating cavity 11, as well as the positive pressure flow and vacuum pumping in the accommodating cavity 11, so that the oxygen content in the accommodating cavity 11 is controlled within ≤20 ppm, making the environment more suitable for the treatment of oxygen-sensitive materials.

[0060] In one embodiment, the controllable atmosphere mechanism 40 includes at least a first sensor 41 and a second sensor 42, both of which are installed within the accommodating cavity 11. The first sensor 41 detects the oxygen concentration within the accommodating cavity 11, and the second sensor 42 detects the concentration of an inert gas within the accommodating cavity 11. Here, the inert gas can be nitrogen, argon, or the like.

[0061] Of course, the controllable atmosphere mechanism 40 also includes an electric valve, an inert gas generator, a first pipeline, and a second pipeline. The inert gas generator is connected to the interface 14 through the first pipeline and is signal-connected to the second sensor 42. An electric valve is installed on the first pipeline to control its opening and closing. One end of the second pipeline is connected to the interface 14, and the other end is connected to a vacuum pump or the atmosphere. An electric valve can also be installed on the second pipeline. Here, when it is necessary to evacuate the accommodating cavity 11, the electric valve on the second pipeline opens, and the vacuum pump evacuates the accommodating cavity 11 through the second pipeline and the interface; when it is necessary to control the inert gas content, the electric valve on the first pipeline opens, and the inert gas generator introduces inert gas into the accommodating cavity 11 through the second pipeline and the interface.

[0062] In one embodiment, the infrared heat source 50 is configured as an infrared heating lamp, and the wavelength of the infrared heating lamp is configured as mid-wave and / or far-wave. This configuration allows the infrared heat source 50 to effectively penetrate into the sensitive material for thermal curing and synergistically improves the thermal curing effect.

[0063] Preferably, the wavelength of the infrared heat source 50 is set to 3-14 micrometers. Specifically, the wavelength of the infrared heat source 50 can be 3 micrometers, 4 micrometers, 5 micrometers, 6 micrometers, 7 micrometers, 8 micrometers, 9 micrometers, 10 micrometers, 11 micrometers, 12 micrometers, 13 micrometers, 14 micrometers, etc. Of course, it is not limited to these, and the wavelength of the infrared heat source 50 can also be set according to actual needs.

[0064] Please refer to the detailed information. Figure 4 The experimental online thermosetting evaluation device 100 also includes a sliding mechanism 60, which is installed inside the accommodating cavity 11. The tray 30 is disposed on the sliding mechanism 60 and can slide out or into the accommodating cavity 11 through the first opening under the action of the sliding mechanism 60. In this way, it is convenient for the tray 30 to slide out and be placed into the accommodating cavity 11, thereby making it easier for the user to operate the tray 30.

[0065] Specifically, the sliding mechanism 60 includes a slide rail 61, a slider 62, and a mounting base 63. The first opening 13 is located on the side wall 12 of the receiving cavity 11 in the width direction Y of the housing 10. The slide rail 61 extends along the width direction Y of the housing 10 and is mounted on the side wall 12. The slider 62 slides in cooperation with the slide rail 61, and the mounting base 63 is mounted on the slide rail 61. The tray 30 is mounted on the mounting base 63. When it is necessary to take out or put in sensitive materials, the door 20 can be opened first, and then the tray 30 can be pulled. Under the action of external force, the tray 30 drives the slider 62 to move along the slide rail, thereby allowing the tray 30 to slide out or into the receiving cavity 11 through the first opening 13.

[0066] Furthermore, the number of slide rails 61 is set to two, and the two slide rails 61 are spaced apart in the length direction X of the housing 10. The mounting base 63 is connected to the two slide rails 61 respectively through the slider 62. In addition, in the height direction Z of the housing 10, the slide rails 61 are mounted on the bottom side wall 12 of the accommodating cavity 11.

[0067] Preferably, a handle 64 is provided on one side of the first opening 13 of the mounting base 63. In this way, the operator can easily push and pull the mounting base 63 through the handle 64.

[0068] Please see Figure 1 , Figure 2 as well as Figure 5 As shown, the experimental online thermosetting evaluation device 100 also includes an observation window 70 and a sealing cover 80. The observation window 70 is located on the housing 10, and a high-temperature resistant transparent plate 71 is installed at the observation window 70, which can block and seal the observation window 70. The sealing cover 80 is movably connected to the housing 10 and is used to open and close the observation window 70. It can be understood that by setting the observation window 70, the operator can easily detect the thermosetting process of sensitive materials from a visual perspective in real time without affecting the thermosetting process, and observe the morphology, color change, bubbling, desorption, and other states of the sample, so as to adjust and control the thermosetting process parameters in a timely manner based on the window effect. At the same time, the sealing cover 80 seals the observation window 70. Of course, when the user does not need to observe, the sealing cover 80 can be placed on the observation window 70 to prevent the heat in the accommodating cavity 11 from escaping through the observation window 70. When the user needs to observe, the sealing cover 80 can be opened and the current thermosetting state of the sensitive material in the accommodating cavity 11 can be observed through the high-temperature resistant transparent plate 71, making it more convenient to use.

[0069] Furthermore, in the height direction Z of the enclosure 10, the observation window 70 is located at the top of the enclosure 10. This arrangement allows the operator to observe changes in sensitive materials from a top-down angle, thus providing a wider field of vision and making use and observation more convenient.

[0070] Here, the high-temperature resistant transparent plate 71 can be a component such as quartz glass or high-silica glass.

[0071] Please continue reading. Figure 1 The sealing cover 80 is rotatably connected to the housing 10 via a hinge. This structure is simple, low-cost, and more convenient to use. Alternatively, the sealing cover 80 can be rotatably connected to the housing 10 via a pivot.

[0072] Furthermore, such as Figure 8 As shown, the sealing cover 80 includes a main body 81 and an insulation layer 82. The main body 81 is movably connected to the box 10, and the insulation layer 82 is disposed inside the main body 81 to improve the insulation effect of the main body 81. Here, the insulation layer 82 is made of a heat-sensitive material, such as ceramic fiber blanket, polycrystalline alumina fiber, chromium-containing fiber blanket, etc.

[0073] A handle 83 is provided on the sealing cover 80. Here, the handle 83 is used by the operator to hold and control the opening and closing of the observation window 70 by the sealing cover 80. It should be noted that the form of the handle 83 is not limited; it can be a groove, a protrusion, or a door handle-like feature, and there is no limitation here.

[0074] In one embodiment, the experimental online thermosetting evaluation device 100 further includes a lighting lamp disposed inside the accommodating cavity 11 to illuminate the interior of the accommodating cavity 11, thereby facilitating an observer to observe changes in the sensitive material through the high-temperature resistant transparent plate 71.

[0075] Here, the light can be a constantly lit light, or its switch can be linked to the opening and closing of the sealing cover 80; that is, the light turns on when the sealing cover 80 is open and turns off when the sealing cover 80 is closed. Specifically, the opening and closing of the sealing cover 80 can be detected by a sensor, and the light switch can be controlled by the sensor signal. Furthermore, since the interior of the accommodating cavity 11 is a high-temperature environment, a high-temperature resistant lamp is selected for the light.

[0076] Please continue reading. Figures 1 to 3 The experimental online thermosetting evaluation device 100 also includes casters 200, which are located at the bottom of the housing 10 in the height direction Z. Thus, the casters 200 facilitate the deployment and movement of the experimental online thermosetting evaluation device 100 within cleanrooms or research platforms, making its use more flexible and versatile.

[0077] In one embodiment, after the experimental online thermosetting evaluation device 100 is moved into position, to facilitate the adjustment and use of the experimental online thermosetting evaluation device 100, this application also provides a horizontal adjustment mechanism. This mechanism can adjust the casters 200, thereby ensuring that the position of the experimental online thermosetting evaluation device 100 after movement is relatively horizontal and stable. Here, the horizontal adjustment mechanism can be configured as an upgrade mechanism, thereby adjusting the position of the casters 200 through an upgrade method; of course, it is not limited to this, and the horizontal adjustment mechanism can also be other mechanisms capable of horizontal position adjustment, which will not be elaborated here.

[0078] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0079] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
