Height for Wave Soldering ERLANGER, KY — Most wave soldering systems have one or two solder nozzles that generate

a turbulent wave. This configu- ration is suitable for most prod- ucts, but it has limitations, such as soldering boards with masks. Depending on the thickness


of the masks and size of the cutouts, it is not easy to guaran- tee that every solder joint will be wetted reliably. Also, reproduc- ing the process can be difficult if the distance between covered SMT components and THT pins is very small. SEHO has developed auto-


matic nozzle height adjustment for wave soldering, providing an innovative solution for these ap- plications. The height of each nozzle can be adjusted by soft-


justment provides additional process stability, as all joints are reliably wetted and component- specific and defined solder peel- off is enabled. In the MWS series, the sys-


tem is linked to its sector-solder- ing feature. This function allows program parameters to be set for pump revolution speed (wave height) and conveyor speed for


up to 16 segments of a PCB. Contact: SEHO North Amer- ica, Inc., 1445 Jamike Avenue,
