Solder nozzles are a central element of selective soldering. They work precisely at the contact point between the solder and the assembly. Nevertheless, they are often underestimated. As the world market leader in the field of selective soldering, Kurtz Ersa also has extensive know-how on the subject of solder nozzles.
Problems with the service life?
Ersa has made the wettable solder nozzle socially acceptable. Initially ridiculed, its advantages in the process have long since made the wettable soldering nozzle the industry standard. The disadvantage of wettable nozzles has always been their limited service life. Due to ageing processes, the wettability of the surface decreases and the soldering properties deteriorate. This process is unavoidable, but can be delayed by the quality of the nozzles and optimized process control.
Ersa original solder nozzles are manufactured according to Ersa specifications from precisely selected materials. The final coating is applied in-house in order to have absolute control over the quality of the wettable surface. This ensures optimum service life in the field. The second important aspect for the service life of solder nozzles is the conditions in the process. As these are different for every customer and every application, there are no general statements about the service life of a solder nozzle. However, Ersa supports every customer in optimizing the respective environment. With the help of experienced experts, you too can get the most out of your solder nozzles!
One size does not fit all
Solder nozzles are like suits. First of all, you have to find the right size (for your application). In exceptional cases, the only thing that helps is a tailor-made suit. And as with a suit, a little bigger or a little smaller may be fine, but you won't be really happy with it.
Ersa therefore offers a large number of standard soldering nozzles. Different diameters (4.5 to 35 mm), different lengths (up to 90 mm long), variants for fine pitch or power electronics. There is already a suitable nozzle for many requirements. And if nothing fits, our specialists also develop special nozzles for more complex applications together with the customer. This cooperation has not only resulted in numerous patents, but also in successful production processes.
