Description

Technical Field

[0001] This utility model belongs to the field of semiconductor packaging technology, specifically relating to a SIP baking and curing device. Background Technology

[0002] In the SIP packaging process, various types of packaging materials are used, such as epoxy resin, silicone gel, and underfill. These materials are used to fill the gaps between the chip and the substrate or to cover the chip surface in a liquid state to provide mechanical protection and electrical insulation. The baking and curing device heats these materials to cause a chemical reaction, thereby hardening them into a solid state, ensuring the stability and reliability of the packaging.

[0003] In some existing SIP baking and curing devices, operators typically need to monitor the temperature gauge in real time and manually open or close the cooling valves based on the temperature displayed on the gauge to regulate the temperature inside the oven and ensure that the temperature inside the oven remains constant. Operators may find it difficult to manually adjust the cooling valves in time according to temperature changes, resulting in large temperature fluctuations inside the oven. These temperature fluctuations may affect the curing quality of the encapsulation material, leading to insufficient curing or overheating damage. Utility Model Content

[0024] Embodiment

[0025] Refer to Figures 1-4 For the embodiment of the utility model, the embodiment provides a SIP baking and curing device, which can realize the effect that the toothed plate 205 is automatically opened or closed according to the real-time temperature change in the oven 100.

[0026] Oven 100;

[0027] It should be noted that the oven 100 can provide a uniform heating environment for the SIP package, by precisely controlling the temperature distribution, to ensure that each part of the entire package can be subjected to consistent heat, avoiding local overheating or overcooling, the oven 100 is the prior art, and the working principle of the present scheme is not described, and the person skilled in the art can clearly know the working principle.

[0028] The temperature control mechanism 200 comprises a fixed plate 201 fixedly connected to the top of the oven 100, a support shaft 202 fixedly installed on the outer surface of the oven 100 through a bearing, a first gear 203 fixedly sleeved on the outer surface of the support shaft 202, a gear ring 204 meshed with the outer surface of the first gear 203, toothed plates 205 respectively meshed with the inner surfaces of the four sides of the gear ring 204, fixed columns 206 respectively fixedly connected to the outer surfaces of the four sides of the fixed plate 201 and matched with the toothed plates 205, limiting blocks 207 fixedly connected to the outer surface of the gear ring 204, and a positioning plate 208 fixedly sleeved on the outer surface of the fixed plate 201.

[0029] Specifically, the heat dissipation opening of the oven 100 is arranged below the toothed plate 205, the outer surface of the first gear 203 extends to the inner side of the positioning plate 208, and the toothed plate 205 is rotatably sleeved on the outer surface of the fixed column 206.

[0030] It should be noted that when the support shaft 202 rotates, the first gear 203 can be driven to rotate synchronously, so that the first gear 203 drives the gear ring 204 to rotate, and the gear ring 204 drives the toothed plate 205 to rotate with the fixed column 206 as the center, so that the heat dissipation opening of the oven 100 is opened.

[0031] Further, the temperature control mechanism 200 further comprises a limiting groove 209 arranged on the outer surface of the positioning plate 208 and matched with the limiting block 207, and a driving assembly 210 capable of automatically controlling the opening and closing size of the toothed plate 205 according to the internal temperature change of the oven 100.

[0032] Preferably, the driving assembly 210 comprises a fixed box 210a fixedly connected to the top of the oven 100, a thermal expansion block 210b fixedly installed on the inner wall of the fixed box 210a, a sliding block 210c in sliding contact with the inner wall of the fixed box 210a and matched with the thermal expansion block 210b, and a connecting rod 210d fixedly connected to the outer surface of the sliding block 210c.

[0033] It should be further noted that the thermal expansion block 210b can rapidly expand in volume after being heated and can rapidly recover after cooling without manual intervention. After the thermal expansion block 210b expands, the sliding block 210c can be extruded, so that the sliding block 210c drives the connecting rod 210d to move linearly.

[0034] It should be noted that the driving assembly 210 further comprises a rack 210e fixedly connected to the penetrating end of the connecting rod 210d, and a second gear 210f engaged with the outer surface of the connecting rod 210d and matched with the support shaft 202.

[0035] When the connecting rod 210d moves linearly, the rack 210e is driven to move synchronously, and the rack 210e drives the second gear 210f to rotate.

[0036] Further, the driving assembly 210 further comprises a spring 210g sleeved on the outer surface of the connecting rod 210d, a support frame 210h fixedly connected to the top of the oven 100 and matched with the rack 210e, and a plurality of ventilation grooves 210i opened above the oven 100 and matched with the thermal expansion block 210b.

[0037] It should be noted that the ventilation grooves 210i are used to transfer the temperature inside the oven 100 to the fixed box 210a, and then the fixed box 210a transfers the temperature to the thermal expansion block 210b.

[0038] Specifically, the outer surface of the limiting block 207 is in sliding contact with the inner wall of the limiting groove 209, the outer surface of the connecting rod 210d is in sliding contact with the inner wall of the fixed box 210a, the outer surface of the second gear 210f is fixedly connected with the outer surface of the support shaft 202, the spring 210g is located on the inner side of the fixed box 210a, the outer surface of the rack 210e is in sliding contact with the inner wall of the support frame 210h, and the plurality of ventilation grooves 210i are located directly below the fixed box 210a.

[0039] In use, the SIP package is placed inside the oven 100 for baking and curing, part of the hot air inside the oven 100 rises to the outside of the oven 100 through the ventilation grooves 210i, and transfers the temperature to the fixed box 210a, and then the fixed box 210a transfers the temperature to the thermal expansion block 210b.

[0040] When the temperature inside the oven 100 is too high: the thermal expansion block 210b is rapidly expanded in volume after being heated, the thermal expansion block 210b is extruded against the sliding block 210c, the sliding block 210c drives the connecting rod 210d and the rack 210e to move linearly while extruding the spring 210g, then the rack 210e drives the second gear 210f to rotate, the second gear 210f drives the support shaft 202 and the first gear 203 to rotate synchronously, the first gear 203 drives the gear ring 204 to rotate, and the gear ring 204 drives the gear plate 205 to rotate with the fixed column 206 as the center, so that the heat dissipation port of the oven 100 is opened.

[0041] When the temperature inside the oven 100 returns to normal: the thermal expansion block 210b cools down, the sliding block 210c, the connecting rod 210d and the rack 210e are reset by the reaction force of the spring 210g, the rack 210e drives the second gear 210f, the support shaft 202 and the first gear 203 to reset, and then the first gear 203 drives the gear ring 204 and the toothed plate 205 to reset, so that the heat dissipation port of the oven 100 is closed.

[0042] In summary, through the cooperation between the various components in the temperature control mechanism 200, the toothed plate 205 can be quickly and automatically opened or closed according to the real-time temperature change inside the oven 100 without manual intervention, thereby dissipating heat or insulating the inside of the oven 100, greatly reducing the temperature fluctuation, avoiding the phenomenon of temperature overshoot or overcooling caused by manual operation, and achieving the effect of avoiding human temperature control error and ensuring the consistency of the quality of each batch of products.
