Compact reflow oven handles lead-free
processing
The Solano is a full convection reflow oven for lead-free processing.
New from Dima SMT Systems is the Solano, a full convection reflow oven for lead-free processing Making a large oven capable for lead free soldering is not a big challenge; but keeping an oven within a limited size and still being able to produce a wide variety of boards lead free is a real challenge

Flexibility is key to handling lead-free reflow
The success of a reflow oven is not measured in its size or the number of heating zones, it is determined by the ability to create every possible reflow profile.
Upgrade kits boost dispensing robot versatility
Three new upgrade kits for the successful Dotmaster dispensing robot enable it to dispense lines, arcs, circles and spirals in addition to its standard dots.
Dima has succeeded in building a full convection circulating hot air oven capable of lead free soldering with only four top heating zones and one bottom heating zone.
Additional bottom heating zones can be added as an option.
The total tunnel length has been kept to only 2250mm including one cooling zone.

The Dispense Master is billed as a new standard in dispensing technology.
In such a compact oven it is extremely important to avoid IR emission sources that can cause uneven heating.
Uneven heating can cause lower-density components to heat up faster than larger ones.
This is a danger when using heating chambers made of heavy aluminium castings with the heating elements inside.
In the Solano this problem has been eliminated by sheeting the entire interior with thin, lightweight, mirror-like polished stainless steel with heating elements placed outside the chamber.
The circulating air speed within the Solano is 1-1.3m/s.
Slower air speeds can lead to imbalance between components and the air surrounding them.
Faster air speeds can cause chips to be misaligned or shifted during the reflow process.
The microprocessor controlled Solano can be used inline, or stand alone by using a vibration-free mesh belt or pin conveyor.
The pin conveyor is adjustable in width allowing PCB sizes ranging from 30mm up to a maximum of 450mm.
The mesh belt allows PCBs to a maximum width of 500mm.
The conveyor and belt speed of the Solano is adjustable from 50 to 800mm/min.
The Solano has five controlled heating zones and one cooling zone, each with a temperature control accuracy of 0.1C.
Consistent edge-to-edge temperatures are maintained regardless of component size or density.
An ioniser is fitted as standard in the cool down zone to eliminate the possibility of damage caused by static charges.
The Solano is equipped with a DimaSoft reflow profiler that is can store up to six different reflow profiles.
Up to 99 different heating programs can be stored in the microprocessor of the Solano.
Through the RS232 interface an optional PC with oven manager software can be connected providing unlimited storage capacity for profiles and programs.
The heating cells of the Solano can be removed from the top side without dismantling the process chamber, making the Solano extremely service friendly.
Easy exchangeable flux traps minimise the contamination of the oven.
