Abstract

The invention discloses a nitrogen filtering recovery system of a reflow oven, comprising a gas inlet (1) and a gas outlet (2), wherein a gas filtration device (3) and a negative pressure power device (4) are sequentially connected between the gas inlet and the gas outlet; the nitrogen filtering recovery system is characterized in that the gas filtration device (3) is arranged in a sealing way, the negative pressure power device (4) is independently arranged outside the gas filtration device (3), and the gas filtration device (3) is communicated with the negative pressure power by a pipeline. The system has obviously excellent filtering effect, reliable sealing performance and convenient assembly and disassembly, can be used for recovering scaling powder in a centralized way, and is applied to the field of gas circulating purification technology of the reflow oven.

Description

technical field [0001] The invention belongs to the technical field of reflow soldering furnace gas circulation purification, and in particular relates to a nitrogen filtration recovery system of a reflow soldering furnace which can be easily maintained and cleaned. Background technique [0002] Surface mount technology (SMT) can be carried out on a fully automated production scale, and components can be mounted on both sides of the PCB to achieve high-density assembly; even the smallest size components can be precisely mounted, so high-quality products can be produced PCB assembly. Surface mount technology (SMT) can be divided into two types according to the soldering method: reflow soldering and wave soldering. [0003] Generally, SMD components are mounted by reflow soldering. First, use the printing machine to scrape the solder paste on the pads on the printed circuit board; then, use the placement machine to press the chip components to the corresponding soldering pos...
