Smart Heat Soldering Set SmartHeat® Technology by OK International/Metcal has allowed for more control during soldering without having to use higher tip idle temperatures as you otherwise would. So, how does it work? SmartHeat® Technology determines the exact thermal demands for individual solder joints and delivers the necessary amount of thermal energy at the rate needed to produce a reliable connection. In doing such, the risk of electronic component damage is decreased, which is especially important with higher thermal demands of lead-free practices.

What makes SmartHeat® Technology different?

1. Delivers Direct Power – The flux activation and intermetallic bond formation are the two most important phases of conduction soldering. As opposed to traditional ceramic heaters that typically adjust the tip idle temperature to deal with heightened lead-free requirements, SmartHeat® technology senses the specific thermal needs and delivers accordingly.

2. Stored Thermal Energy Transfer – Because stored energy is directly correlated with tip mass and tip idle temperature, other heater soldering systems approach higher demands by raising tip idle temperature. However, SmartHeat® systems are able to distribute thermal energy at lower temperatures and lower the risk of component damage.

3. Reduces Risk of Overshoot – Thermocouple sensors and ceramic heaters used in other technologies often produce temperature discrepancies, along with unstable solder connections. SmartHeat®, though, detects the energy requirements before temperature deviation becomes a problem.

4. Provides Temperature Stability – Other ceramic heater systems rely on the sensor, heater, and operator set point controls to provide temperature stability, but these can be inconsistent. The repeatability of SmartHeat® technology is automatically established by the molecular properties of the heater material, which provides stability over time.

5. Precision Tip Selection – Because the tip is the main tool used to provide thermal energy from the heater to the pad, tip selection is of utmost importance. OKI’s Power Meter can determine specific pad energy requirements, which allow you to narrow down your choices when choosing a tip.

6. Perfect for Lead-Free – Reliable lead-free soldering connections are based upon high thermal demands. Because SmartHeat® technology allows for more accurate control, you can produce more stable connections at low operating temperatures required by lead-free applications.

7. Increase Tip Life and Value – Since SmartHeat® allows you to solder at lower temperatures, and tip selection is easier with the Power Meter, you will enjoy longer and more valuable tip lives.

What is OKi’s SmartHeat Technology?

OKi Metcal SmartHeat Technology

Many of OKi’s new soldering systems including the OKi PS-900 feature SmartHeat Technology. This technology is basically ESP for your soldering system. Any system that features the SmartHeat will sense the thermal requirement needed for each job and then deliver the correct thermal energy needed to create a reliable joint without using a super high temperature. This sensing reduces the risk of component damage.

Below are some of the benefits of OK International’s SmartHeat Technology.

  • Transfer of Stored Thermal Energy – Conventional soldering systems store the thermal energy in the tip and once the tip touches the pad, the energy rushes into the pad. But SmartHeat Technology allows the system to act differently depending on the pad’s thermal demands which once again gives the operator the thermal energy needed at the lowest temperature possible.
  • Reduced Risk of Undershoot and Overshoot – SmartHeat detects the energy requirement and then controls that energy to avoid an unreliable joint or damage to PCBs or components.
  • Temperature Stability Over Time – The molecular properties of the material used in the heater don’t shift over time and that’s why SmartHeat systems do not need recalibrated or recertified.
  • Rating System to Help with Tip Selection – Choosing the correct soldering tip is important, after all it’s how all the energy travels from the heater to the pad. That is why OKi developed the conductivity factor rating system to provide operators with the guidance they need. Also, OKi’s power meter can quantify the energy requirements needed for the pad.
  • Ideal for Lead-Free – The thermal energy needed for lead-free soldering is greater than the energy needed for leaded solders. Systems with SmartHeat offer the thermal energy needed for lead-free but at lower operating temperatures.
  • Longer Tip Life – High tip temperature combined with oxidation and flux corrosion can rapidly deteriorate the working life of a soldering tip. A soldering system with SmartHeat Technology operates at a lower temperature so soldering tips are less affected by chemical interactions and the high heat.
