Wave soldering refers to the flow of molten solder (lead-tin alloy) into the solder wave required by the design through an electric pump or an electromagnetic pump.
It can also be formed by injecting nitrogen into the solder pool to make the pre-installed components.
The printed board realizes the soft soldering of the mechanical and electrical connection between the soldering ends of the components or the pins and the pads of the printed board through the solder wave.
The main purpose of wave soldering with nitrogen filling is to reduce the amount of oxidation of the solder.
Selective wave soldering, the gassing ring should be replaced after some time.
After a period of use, the precision of the seals for the gassing ring and gasification ring will decrease, and the quality of the gas output will not be very good.
Nitrogen Generator Desktop Selective Wave Soldering The Selective wave soldering nitrogen sealing ring is made of graphite material, which has a sealing function, and also has a silicone material, but the silicone material is easily damaged.
