Nitrogen Selective Soldering Machine NP-350-N
Highlights selective soldering machine NP-350-N:
Due to increasing product changes in electronics production, it is necessary to exchange solder nozzles or readjust solder pots by hand. The new HB NP-350-N sets new standards with regard to flexibility - the solder module is available for NP-350-N selective soldering systems.
The solder pot is installed on independent axe. In this way, the pot can be moved and adjusted individually in x/y/z-direction. In addition, to meet all tomorrow´s requirements HB offers an upgrade package for the NP series module which allows to independently solder two individual joints at the same time.The solder pot can be added flexible according to the requirements of customers.
Q:What is the function and principle of wave soldering preheating?
A:1.In the process of wave soldering, the flux is activated firstly, and then the metal surface oxide film, grease and other impurity are removed.
2.In order to prevent spray when the PCB cross solder pot, the solvent and water in the flux should be removed.
3.Removed the water in the PCB.
4.Increase the temperature of the PCB and components, which can prevent PCB from cracking.
