In vapor-phase soldering (condensation soldering), soldering is accomplished using a hot vapor. In this case, the heat transfer in condensation soldering is up to ten times higher than with convection soldering. This means that with the Condenso series from Rehm even large, high-mass boards can be reliably processed in a stable atmosphere and with innovative vacuum technology. The CondensoXM smart vapor-phase soldering system can be integrated into any production environment – incorporated as an island solution for several production areas and loaded manually or loaded automatically using upstream handling systems. To ensure this optimum inline capability, the CondensoXM smart is equipped with an outer return transport for the goods carrier. This reduces cycle times and ensures optimum soldering results even with larger volumes. The CondensoXM smart can be opened on the operator’s side to load or remove assemblies, meaning that assemblies can be manually placed on or removed from a goods carrier which is already in the system. The goods carrier remains in the system, which enables ergonomic loading.
The CondensoXM smart can be equipped with an additional vacuum pump. This increases reliability, which is needed in particular for critical assemblies which make increased demands on the vacuum process. Moreover, two vacuum pumps can be used to shorten the cycle time and so increase productivity for vacuum applications under 10 mbar in particular. Virtually void-free soldering results can also be achieved with the vacuum option. After soldering, the assembly is passed on and into the cooling process. At the same time, process gas is extracted and cleaned. A large part of the Galden® can therefore be reused – a solution that is particularly material-friendly and environmentally friendly! A vacuum is created during extraction, which also ensures that soldering material is dried quickly. The extracted Galden® is filtered and cleared of impurities using granules. About 99.9% of the medium can be recovered as a result.
Flexible cooling options inside and outside the process chamber guarantee optimal cooling rates and the correct temperature for downstream production processes, such as x-ray inspection or functional testing.
