With all Condenso series systems, the soldering process

takes place in a hermetically sealed process chamber made

of aluminium or a mix of stainless steel and aluminium. The

processchamberisttedwithhigh-qualityelectricpanelhe-

aters that ensure optimum process conditions. The assem-

bly is heated up to soldering temperature by injecting and

vaporising Galden

. Steam allows for optimum heat transfer

to the soldering material. The heating systems’ target

temperature value remains constant. Therefore, excellent,

reproducible soldering results are ensured. The Galden

fully extracted after the soldering process, and air is blown

in via a nozzle system to gently bring the assemblies to

lower temperatures before the actual cooling process. The

systemscanbeoptionallyttedwithaviewingwindowor

camera so that the soldering process can be observed and

analysed. Soldering defects can be detected and eliminated

in a timely fashion as a result.

The residues that remain in the soldered joint can

escape more easily due to the vacuum. The Con-

soldered joints with a surface binding proportion

of up to 99 %. Vacuum can also be drawn during

the melt phase, even before the actual solder-

ing process. This doesn’t just allow the Galden

steam to be evenly distributed in the process area,

but also enables the solvent and moisture to be

de-gassed from the solder paste. In addition, the

atmosphere can also be varied in the process

chamber throughout the whole dwell time as well

the temperature.
