ASSCON’s vapor phase soldering systems based on newest technologies (Image 4) have eliminated the disadvantages inherent to early condensation systems, soldering with unsaturated vapor and injection systems. By employing saturated vapor not only for the heating but also the pre-heating phase, any risk of oxidization is eliminated. In addition, precise medium temperature settings eliminate overheating of the product in any stage of the soldering process. Variable temperature gradient control provides optimum pre-heat and soldering for any product. The intelligent, but mechanically simple vertical structure of today’s saturated vapor soldering systems allows for automatic identification of the end of the soldering process.And finally one of the most important benefits: As almost all other process parameters remain constant when soldering in saturated vapor, the only parameter an operator needs to set is the required temperature gradient. The technology does not require setting multiple parameters as is necessary when soldering by injection or with unsaturated vapor. Therefore saturated vapor soldering with variable temperature gradient adjustment achieves maximum process stability and repeatability – factors that are especially important when considering today’s switch to lead-free manufacturing.

Void-free soldering with a new vapor-phase with vacuum technology

Voids in solder joints are largely a function of differential pressure between vapor pressure of the gases inside of the joint and environmental conditions. By entering joints still in their liquid state into decompression chambers, voids can be eliminated.

Vapour Phase Process

The modern production of electronic assemblies in SMD-technology is unthinkable without the efficient printing process, placement process and particularly the soldering technology. In particular, for a high and constant product quality the soldering technology is of utmost importance. From the start of the SMD-technology there have been two processes competing constantly with each other.
