OLDERWAVE SETTING
1. Check the smart or mainwave nozzle is correctly levelled. Easy to do by reducing the
pumpspeed to the point that the solderflow is breaking from the nozzle rim. The solder must
break over the total width. Use the screws in front and rearside of the sump to correct.
2. Adjust the nozzle rim to the inside of the finger groove (s).
b = board thickness
p = protruding lead length solderside
c = clearance between lead and nozzle rim (
≥
1 mm 0.04”)
s = c + p + 1/2*b
3. Place the Vitronics Soltec glass test plate (partnr. 627.3785) in the conveyor. Distance s from
the nozzle rim. (See figure above). Make sure that the underside of the glassplate is at the
same distance as the underside of the PCB.
4. Set smart or mainwave on continuous. Raise the smart/mainwave to the point that the
contactlength L is the desired length. Adjust the backplate if necessary.
The conveyor speed can be calculated: V = L / t.
Example: Contactlength L = 40 mm.
Desired soldertime t = 2 sec.
Conveyor speed: V = 40/2= 20 mm/s = 120 cm/min.
