Problems solved by technology
[0004] The jet flow wave soldering furnaces on the market are all low-temperature tin furnaces (less than 350 degrees Celsius). With the continuous updating of electronic products, higher reliability, better high temperature resistance and low temperature resistance performance are required, and the volume is getting smaller and smaller. The requirements for soldering are getting higher and higher. Some transformers and inductance products need high-temperature jet wave soldering (less than 450 degrees Celsius), but low-temperature tin furnaces on the market can no longer meet this welding demand; high-temperature jet soldering tin furnaces are usually used as supporting equipment
The existing wave soldering furnace equipment needs regular maintenance, and it is difficult to clean after use. It needs to wait for the tin furnace to cool down before cleaning, and the maintenance takes a long time

Description
technical field [0001] The invention relates to the technical field of electronic welding equipment, in particular to a low-fluctuation and easy-to-maintain tin furnace pump and a wave soldering tin furnace. Background technique [0002] Jet wave soldering is also called jet soldering and high-speed wave soldering. It is applied in the field of PCB plug-in through-hole welding and automotive electronics industry equipment. The popular trend of welding, the scope of application is not limited to: military electronics, aerospace ship electronics, automotive electronics, digital cameras, printers and other multi-layer PCB through-hole welding with high welding requirements and complicated processes. [0003] Manual welding can also realize the welding of inserts, but the quality of manual welding is too dependent on the operator's work skills and proficiency, and the repeatability is poor, so it is not suitable for automated production. In the above background, selective solde...
