QUICKSILVER VERTICAL LEVELERů..take a closer look
- Compared to similar sized systems Quicksilver (QS) uses approx
10kw less power. 10-20kw per hour is used during normal operation
depending on duty cycle (panels processed per hour). The QS is well
insulated, having a sump capacity of 235kg (610mm x 610mm Lead Free
solder machine) compared with up to aprox 320kg for other systems.
The surface area of the solder that is exposed to the atmosphere
(chilling area) is relatively small in the Quicksilver. The QS
design allows solder to weir over a relatively narrow channel
(dividing the dip and pump zone) aprox 100mm when the pump is
running at maximum. Most other systems employ a design similar to
that of wave soldering machines. Solder overflows around the full
periphery of the solder pot into a channel that surrounds it. This
creates more dross and also has a greater cooling effect on the
solder, requiring more heat energy to maintain temperature.
- QS is the only machine to incorporate a highly efficient,
patented combined airknife/heat exchanger. There is less heat loss
because the air knife section is an integral part of the heat
exchanger. Incoming air to the aluminium block heat exchanger passes
through a series of ports providing maximum efficiency, ensuring
there is little or no air that is not directly heated by the heat
Most, if not all other systems employ a remote heat exchanger
container fitted with heaters. The air is passed through a large
bore pipe that is in contact with the heaters. While the air is
hottest at the wall of the pipe, the air at the centre of the pipe
is cooler. As a result the air has to be heated far higher than the
290C air operating temperature of the QS. In most cases remote heat
exchangers require air to be continuously fed to the knives in an
effort to keep them hot.
- QS incorporates an easy maintenance swing out solder pump. This
takes less than 1 minute to access the pump compared to aprox 15
plus minutes for other systems. The pump is located in the pump
zone. It transfers solder down a flow pipe to the bottom of the dip
zone. Multiple exit holes within the base of the flow pipe allow
solder to freely circulate upwards across the entire dip zone
eliminating any static or cold spots.
- Swing Back upper section is provided allowing total sump access
for cleaning and pump zone heater replacements.
- Easy to use operator controls (even with gloves on). In addition
to the touch screen controls the QS also has large push button
controls for increasing/decreasing dwell time for preheat (first dip
if selected) and second dip cycles.
- Optional Patented profile panel clamping system. Only the QS is
capable of reworking routed panels that have soldered features up to
the extreme edges of the panel. All other machines require an area
void of circuit features to enable it to be clamped.
- QS Air knives are precision engineered. The tips are
manufactured from high carbon tool steel coated with titanium
nitride (a gold looking coating similar to coatings used on the more
expensive drill bits). This provides an extremely hard and chemical
resistant coating. The tips are machined with a preset gap and
therefore no need to make any adjustments. The tips are the same
technology as used with the Alchemy horizontal systems. The result -
although the panel is immersed at 90 degrees to the airflow, the
quality of coverage and uniformity is superior to other equipment
offering a 45 degree panel dipping process.
- QS has a smaller footprint.
- Combined extraction/flux containment box with drain (optional).
This is a neat way of collecting spent and airborne flux and having
a central extraction point in one container.
- The sump is made from Boiler Plate (carbon steel) and therefore
is not affected by the aggressive nature of the lead free alloy to
the same degree as stainless steel. The pump housing and impeller
are meonite (cast steel).
