Nozzle geometries

Nozzle technology for selective mini wave soldering

Individual, product-specific solder nozzles are a key component of the EUTECT mini-waves and guarantee reliable and cycle time-optimised solder wetting of the components and substrates to be soldered.

Benefit

EUTECT provides product-specific nozzles for the respective soldering task. Customised, single-sided solder nozzles generate the best possible solutions for the respective challenge.

Performance

For an optimum soldering result, it is important that the geometry of the soldering nozzle, together with the nitrogen bonnet, is matched to the product to be soldered. We therefore develop and design a specific soldering nozzle with a customised gas hood geometry for each customer-specific application. A product-specific soldering nozzle, in combination with product-specific titanium masking and workpiece carriers, enables maximum solder joint quality with a long service life and optimised cycle times.

Modularity

Different soldering nozzles are available:

Point nozzle
Double point nozzle
Line nozzle
Ring nozzle
Matrix nozzle

Significance of the nozzle geometry

Product-specific nozzle geometries play a central role in the soldering process, as they enable the exact placement and dosage of the solder. The shape of the nozzle determines how precisely the solder is applied, especially for small or closely spaced components. A precisely fitting geometry ensures even solder distribution and reduces reworking. Product-specific nozzle geometries also allow the processing of complex PCB layouts. The entire soldering process can be optimised and costs saved thanks to the precise design and production of the geometry.

Customised nozzle geometries

EUTECT not only offers standardised nozzle geometries, but also individual designs that are specially developed for the requirements of the solder joint. Different parameters must be taken into account. For small solder joints or assemblies with high packing densities, the nozzle geometry can be designed to be correspondingly delicate, while larger components with corresponding heat requirements require larger geometries. Furthermore, different solder alloys result in different flow behaviour of the solder, which is influenced by the nozzle geometry. The soldering temperature and duration must also be taken into account when designing the geometry, as the geometry contributes to optimum heat transfer and directly influences the soldering quality.
