Problems solved by technology

When the temperature meets the requirements of small components, the large components cannot reach the melting temperature and soldering cannot be achieved; when the temperature meets the requirements of large components, the small components will be exposed to excessive temperature and cause burning, so how to balance the volume The temperature of large components and small components during soldering and the utilization of heat are improved, which is a great challenge to the SMT process

Abstract

The invention discloses a welding device and a welding method. The welding device comprises a furnace body, multiple hot wind nozzles and at least one welding jig. A furnace cavity is formed in the furnace body. The multiple hot wind nozzles are arranged at the bottom of the furnace cavity. The at least one welding jig is detachably arranged above the multiple hot wind nozzles. A gap exists between the at least one welding jig and the hot wind nozzles. The at least one welding jig is used for conducting shielding and heat transfer guidance when the multiple hot wind nozzles conduct heating and welding on at least two elements of different sizes so that welding of the at least two elements of the different sizes can be completed at the same time.

Description

technical field [0001] The invention relates to a welding device and a welding method, in particular to a welding device and a welding method for simultaneous heating and welding of components with different volumes. Background technique [0002] SMT is Surface Mounting Technology, which is the most popular process technology in the electronic assembly industry. It is a method of installing surface mount components without leads or short leads on the surface of the PCB board, and then soldering the components and the PCB board together through solder paste alloy through reflow; in addition, it combines traditional components Compressed into only a few tenths of the device, thus realizing the high density, high reliability, miniaturization, low cost and automation of production of electronic product assembly. [0003] The patent No. is that the patent of JP 1998-209630A discloses a welding device (see figure 1 ), including: printed circuit board 11 and components 16 and 17 ...
