Basic Configuration of Pulse Heat Unit (Hot Bar Bonder) and Role of Each Part

The object to be joined is held down and the electric current is flown while the pressure is being applied, and heat is generated by resistance heating.

  • Pulse Heat Power Supply: Electric current is flown to the heater tip or the heater tool.
  • Reflow Head: The object to be joined is held down and a force is applied. The applied force is adjusted by a spring.
  • Heater Tip & Heater Tool: This is the part that becomes hot by resistance heating.
    The one with a relatively small area is called”heater tip” and a larger area is called “heater tool”.
  • * In addition to the above, we have various monitors which measure applied pressure

Pulse Heat Power Supply

Select a power supply with suitable welding capacity depending on the material or the shape of the object to be joined and the required quality level.

Standard Type

        Displacement Type             General Purpose Type         High Power Type






Reflow Head

Select a head having a force suitable to the object to be joined and suitable to the heater tip/heater tool to be used.

Heater Tip Type          Heater Tool Type

Heater Tip/Heater Tool

Select the size and shape suitable to the object to be joined. If necessary, it can be machined for custom shape.
A material to which the solder will not stick and easy to heat with high resistance value is used.
