the power of SmartHeat
With little resistance to generate heat, the temperature begins
to drop–but only until it drops below the Curie Point. Then the
skin effect resumes and heating recommences. This can occur
with remarkable speed.
The selection of a material with a given Curie Point results in a
device that will produce and maintain a specific self-regulated
temperature. The result? A system that requires no calibration and
responds dynamically to loads.
SmartHeat technology simplified
We all know what happens when the sun shines on a black
surface like asphalt: The surface absorbs the sun’s energy and
heats up. Conversely, white concrete reflects the sun’s energy
and does not heat up as much. The asphalt heats more because
a black surface is better at absorbing energy than a white one.
Now, imagine what would happen if asphalt could absorb energy
until it reached a pre-set temperature, and then turn white to
reflect the energy away. When the temperature dropped a few
degrees, it would turn black again. You would have a road that
could regulate its own temperature and never overheat or
become icy.
This analogy is close to the way SmartHeat technology works.
The “asphalt” is made from a metal alloy which has the ability
to absorb energy from an electrical field and turn it into heat.
When the alloy reaches a certain temperature, it stops absorbing
energy – in our analogy, it turns white – and its temperature
stops rising. When a solder joint draws heat from the heater, the
alloy reacts immediately by becoming “black” again to take on
more energy and reheat.
At the Curie Point, the skin loses its magnetic

properties, and the skin effect vanishes.
To sum it all up:
Because Metcal Systems use SmartHeat technology,
Metcal can make anyone a rework expert in less time than you’d think
Even a novice can rework difficult boards
with just a morning of basic training
from one of our expert distributors or
representatives.
Metcal’s patented technology and
precision-engineered design assure
consistent results. Tip cartridges like
the SMTC-x147 (hoof) multi-lead speed
soldering cartridge make attaching
QFP-208’s easier than you’ve ever imagined. Removal is just as
quick and easy.
No Calibration makes ISO 9000 compliance easy
Because the interchangeable SmartHeat
heater and temperature self-regulating alloy, SmartHeat
Systems require no calibration.
By specifying the tip cartridge, you’ve specified most of your
process. Just choose the correct tip cartridge, insert it into the
handpiece, and flip one switch. Compare that to the myriad of
dials, readouts, buttons, and calibration tools and procedures of
other systems. This makes compliance with ISO 9000 simple. A
“no-calibration” letter is available on request.
The easiest tip cartridge swap in the industry
Tip cartridges slip in and out with no tools, so you can go quickly
from removing a 100-pin QFP to cleaning up pads with one
of Metcal’s blade tip cartridges and desolder braid, to rapidly
soldering a fine pitch component with our “hoof” tip cartridge.
It’s like having a complete rework station at every bench.
Reduces your maintenance costs
SmartHeat
use no separate control circuits and minimal parts. When you
change a tip cartridge, it’s like getting a whole new system.
They are incapable of overshoot.
There is no need for calibration – ever.
They deliver high throughput at lower temperatures
And you get an easy to use, versatile conduction tool for all
your rework needs.
