Keeping Wave and Selective Soldering Up to Date
By Markus Walter, CEO, SEHO Systems GmbH
currently available are based on vac- uum technology, but this technology has a problem: the heat transfer is really restricted and the vacuum is applied after the peak heating zone. To eliminate the voids, vacuum tech- nology uses the difference between 1 bar (14.5PSI) and almost zero air pressure. At SEHO, we have gone in a dif-
V
ferent direction — working with an elevated pressure in the peak zone, up to 4 bar (58PSI), and then lower- ing it to atmospheric pressure (1 bar). The result is a force that is three times stronger than standard atmospheric pressure, which elimi- nates the voids as well as providing increased flexibility in working parameters. And while the High Pressure MaxiReflow is made for inline applications, it can also be used as a standard inline reflow sys- tem with high throughput if the pres- sure process is deactivated. With this technology in place, the customer will really be ready for the future.
Soldering Developments Since its founding in 1976,
SEHO has become the worldwide contact partner whenever soldering is involved. Company solutions are

based on performance, flexibility, efficiency and technical progress. SEHO’s business activities and pro- duction organization are oriented according to the principles of sus-
tomers with a competitive advan- tage.
Since the company’s founding
more than 37 years ago, SEHO has introduced numerous innovations in
system in the PowerSelective machine. SEHO started a partner- ship with a company that has long- standing experience in optical inspection, making it possible to inte- grate a proven solution into its selec- tive soldering systems. This coopera- tive venture effectively merged the company’s expertise with the part- ner’s experience in optical inspection. The result is a turnkey solution that has just one interface. SEHO recently introduced its
PowerWave N2 wavesoldering sys- tem, transferring experience from
the high-end MaxiWave line into a more affordable concept. New fea- tures of the system include program- mable distances between the solder nozzle and conveyor. In addition, the company has also introduced a void- free solution based on high-pressure technology.

the field of soldering, such as solder- ing in Nitrogen atmospheres.
Incorporating AOI in Soldering A recent development is the
implementation of an AOI inspection
cally reduces Nitrogen and energy consumption by using an insulated tunnel design concept which ensures that emissions from the heaters remain in the process chamber and will not be released to the production environment. The power consump- tion has been reduced by as much as 15 percent. The optimized N2 gassing
