Problems solved by technology
[0002] At present, most solder paste interlayer welding and connection processes use liquid solder paste for dispensing welding operations. Due to the limitations of liquid solder paste storage and use methods: 1. The amount of solder paste dispensed is unstable; 2. The solder paste produced by dispensing is round and inconsistent with the shape of the material to be welded; 3. The liquid solder paste is pressed by the upper and lower layers, resulting in uneven thickness after solidification; 4. The usage of a can of liquid solder paste is limited, and continuous dispensing is not possible Welding, changing the solder paste will affect product quality and production capacity; 5. After the solid solder paste sheet is directly heated to the center point, the solder paste layer will be completely melted and scattered, and the thickness will be thinner

The invention relates to a welding process and welding equipment. The welding equipment includes a laser generator and an adjustable reflector, and the scanning trajectory of the laser beam is controlled by adjusting the reflector to complete welding. The welding process method firstly heats and melts the solid solder paste sheet in the middle, and then controls and adjusts the mirror to move the laser beam to melt around the solder paste sheet, so as to ensure that the thickness of the solder paste layer remains unchanged during welding; the solid solder paste The storage and transportation of the chips are more convenient, the cost is low, and the vibrating plate can be used on the equipment to continuously feed the solid solder paste chips.
