[0002] Bonding equipment is a core component in semiconductor manufacturing and microelectronic packaging, primarily used to achieve electrical connections between chips and substrates or precise bonding between materials. However, current bonding equipment typically uses indirect heating when heating is required. The heating element cannot directly transfer heat to the product being bonded, leading to energy waste during the heating process. More importantly, this indirect heating method easily transfers heat to unheated areas, potentially causing deformation of these non-heated parts of the bonded product, thus increasing the overall defect rate and hindering production.

[0025] Please refer to Figures 1 to 7 The present invention provides a device for local heating and fixing of bonding products, including an extrusion assembly 1, a carrier plate 2, and a heating base assembly 4.

[0026] In this embodiment, a plurality of products 3 to be bonded are arranged on the carrier plate 2. The extrusion assembly 1 is used to extrude each product 3 to be bonded when needed to complete the bonding. The heating base assembly 4 is used to heat each product 3 to be bonded when needed to assist in completing the bonding.

[0027] Furthermore, the carrier plate 2 is provided with a number of cutouts 9, each cutout 9 corresponding to each product 3 to be bonded. Each product 3 to be bonded is located in the corresponding cutout 9. The extrusion assembly 1 is located above any product 3 to be bonded. The heating base assembly 4 is used in conjunction with the extrusion assembly 1 and is located below the corresponding product 3 to be bonded.

[0028] The extrusion assembly 1 includes a pressure plate 11 and several pressure claws 5. The pressure plate 11 is located above the corresponding product 3 to be bonded, and protrusions 6 are integrally formed on both ends of the upper surface of the pressure plate 11. In actual operation, each protrusion 6 is connected to an external pressure device to provide the pressure required for bonding. A clearance opening is provided in the middle of the pressure plate 11, and each pressure claw 6 is detachably and fixedly arranged at the edge of the clearance opening. The lower end of each pressure claw 6 contacts the upper end face of the corresponding product 3 to be bonded, and each pressure claw 6 corresponds one-to-one with the places on the corresponding product 3 to be bonded that need to be extruded. In this way, when the pressure plate 11 is pushed by the external pressure device through the protrusions 6, each pressure claw 6 can perform bonding extrusion on the corresponding product 3 to be bonded.

[0029] Furthermore, the heating base assembly 4 includes a base body 10 and several heating bosses 7. The base body 10 is located below the corresponding product 3 to be bonded and is adapted to the pressure plate 11. The lower end face of the base body 10 is connected to an external lifting assembly, so that the height of the base body 10 can be controlled by the external lifting assembly. Each heating boss 7 is detachably and fixedly mounted on the upper end face of the base body 10, and each heating boss 7 corresponds one-to-one with the part of the product 3 to be bonded that needs to be heated. In this way, the upper end of each heating boss 7 can be made to contact the lower end face of the corresponding product 3 to be bonded by the external lifting assembly, thereby achieving support and heating.

[0030] It should be noted that each heating boss 7 is electrically connected to an external heating control power supply, so that the operation of each heating boss 7 can be controlled by the external heating control power supply.

[0031] Each heating boss 7 is provided with several air holes 8, and each air hole 8 is connected to an external high-pressure air source. In this way, when the work starts, the corresponding product to be bonded 3 can be adsorbed through each air hole 8, thereby ensuring that the corresponding product to be bonded 3 is fixed during heating.

[0032] The working method of the device for local heating and fixing of bonding products in this utility model is as follows: the product 3 to be bonded is placed in the hollow opening 9, and then the extrusion component 1 and the heating base component 4 work simultaneously to accurately heat the part that needs to be heated while extruding and bonding.
