July, 2020 ElEctronic Mfg Products SEHO Debuts Mini-Wave Solder Nozzle


Erlanger, KY — SEHO Systems has launched its LongLife mini-wave sol- der nozzle. The patent-pending noz- zle is compatible with both SEHO se- lective soldering systems and other brands. The LongLife solder nozzle is


manufactured in a special process that does not damage the cubic metal


Maintenance requirements for


the new nozzle are also reduced. The LongLife solder nozzle does not need to be cleaned or reactivated through- out a complete production shift. There is also no activation needed prior to production start. The nozzle is simply inserted, the pump is turned on and production can begin. The LongLife nozzle is ready to solder in seconds. The nozzle also offers some


advantages from a process standpoint. The consistent noz- zle wall enables improved heat energy transfer to the solder joint and the wave height is con- stantly kept stable, ensuring higher overall process stability. The nozzle also improves

matrix. As opposed to the manufac- turing process of a conventional cut surface, this new process does not change the arrangement of atoms at the surface of the nozzle material. The mini-wave solder nozzle is also coated with a special gold alloy, offer- ing some outstanding characteristics. According to the company, the


lifetime of the new nozzle is more than three times that of conventional solder nozzles, under the same condi- tions. This leads to remarkable an- nual cost savings.


soldering quality. In the case of poorly activated solder nozzles, the nozzle center may shift, re-


sulting in solder bridges or washed away SMD components. The Long - Life solder nozzle, however, perma- nently offers perfect activation. The new nozzle also helps to


conserve resources. Its materials usage is quite low and, due to re- duced wear and elimination of chem- ical activation materials, oxides and dross are reduced as well. When combined with SEHO’s


ultrasonic solder nozzle cleaner, maintenance staff are protected, since the process requires no sol-
