In Military Depot environments, a single component can cost thousands of dollars, a circuit card 10 times that, and older electronic modules may be priceless because they are no longer manufactured! Metcal prevents inadvertent damage due to improper repair/rework techniques, improves product quality, increases productivity and reduces repair costs with its patented SmartHeat technology. As SmartHeat maintains

a constant tip temperature, automatically delivering the exact amount of power required for the task, consistent results are guaranteed and component/PCB damage is virtually eliminated. Unlike conventional soldering/desoldering irons, SmartHeat does not require calibration & virtually eliminates the risk of thermal overshoot/undershoot.

SmartHeat^® Delivers Direct Power
First & foremost, the success of a conduction soldering iron depends upon the availability and controlled flow of thermal energy into the connection during the two critical phases - flux activation and intermetallic bond formation. Conventional ceramic or wire-wound heaters attempt to control this process by managing indirect parameters, such as idle tip temperature. In contrast, SmartHeat administers heat directly from the heater to the joint. Metcal tip cartridges detect the thermal load and instantly adjust the power in order to deliver the right amount of heat precisely where it is needed. If the soldering iron tip cools while transferring heat to a joint, SmartHeat immediately responds by safely increasing the power to maintain a constant tip temperature. As a result, electronic workers are relieved of regulating the tip temperature, thus eliminating the risk of thermal damage to the component or to the PCB.

Trouble-Free Tip Replacement
The heat-resistant pad supplied with the unit allows you to easily insert and remove the soldering iron tip cartridge or desoldering tip, within 3 seconds! The swiftness and simplicity of this process ensures there is no loss of productivity, no need for additional tools and no reason for two soldering systems to be heating at the same time.

No Calibration Required!
To meet the demands of temperature stability, conventional ceramic, wire-wound and tip-cartridge heater systems depend on the sensor, heater and operator set point controls. Each of these elements is subject to drift and instability requiring frequent calibration to ensure compliance. By contrast, the repeatability of Metcal SmartHeat Technology is inherently determined by the molecular properties of the heater material and does not shift over time, ensuring long term stability without the need for calibration. As the heater’s alloy dictates the temperature, calibration is not required. Indeed, there are no dials, buttons, digital displays or calibration tools, typical of other systems, with which you can adjust SmartHeat’s temperature. This avoids all risk of unauthorized operator intervention. A letter to confirm SmartHeat’s self-calibration capacity is available by clicking here.

SmartHeat soldering systems comprise three basic elements: a high frequency power supply, a tip cartridge and a hand-piece. The cartridge contains the solder tip, a heater and the wire coil. the temperature of the heater (a copper bar coated with a magnetized iron/nickel alloy) reaches a certain level (its Curie Point), it stops absorbing energy and the temperature becomes constant. Energy from the power supply feeds a steady current to the coil. This creates an electrical field from which the heater absorbs energy, turns it into heat and transfers it to the iron/nickel alloy. When soldering has drawn heat from the heater to the extent that the tip begins to cool, the alloy reacts by taking on more energy in order to reheat the tip. In this way, SmartHeat self-regulates the tip temperature to within ±1.1ºC of a set point regardless of thermal load & without any need for adjustment.
