2) the problem that the solder can only be uploaded regionally is solved by adopting a dispensing mode;
3) the glue is rolled by the roller and then passes through the powder pool, so that the problem of large solder uploading loss is solved;
4) solder does not need to be prepared in advance, so that the requirement of solder preparation on technical personnel is reduced, and the requirement of the use of the solder on the environment is also met;
5) the same performance is achieved, the amount of used welding flux is greatly reduced, and the material cost is reduced;
6) the solder blending work and the drying work are reduced, the production period is shortened, and the production cost is reduced;
7) the problem of carrier hole blocking is solved;
8) the available foil tape cutting mechanism is cut into tapes with fixed length for rolling, thereby ensuring the consistency of the tightness of the carrier and the production efficiency and improving the stability of the quality of the carrier.
