What is Hot Bar Reflow Soldering / Pulse Heat

Pulse Heat is an instantaneous heating method of hot bar reflow soldering, which can instantaneously solder, thermocompression bonding, and resin welding by heat and pressure using resistance heat generated by applying electric current to a metal heating element called the heater chip/heater tool. This is an original method unique of Nippon Avionics.

The Pulse Heat Unit consists of the pulse heat power supply that controls the current, the reflow head that holds and applies pressure to the parts to be welded, and the heater tip/heater tool that contacts the parts to be welded and generates resistance heat.

Compared to the constant heating method, it has less thermal effect on peripheral components and is widely used for narrow pitch soldering and thermo-compression bonding of ACF.

Features of Hot Bar Soldering Machine Pulse Heat Unit

The main application of the Hot Bar Soldering machine Pulse Heat Unit is for soldering electronic components such as information terminals.

Provides temperature control by feeding back the temperature of the heater tip/heater tool. The set temperature profile can be reliably reproduced. Models that can control the amount of melting are also available.

Application examples

  • Heat seal joining and ACF joining for flat panels, such as LCD and touch panel.
  • Soldering of CCD or CMOS used in mobile phones and digital cameras.
  • Soldering of FPC and printed wiring board inside a PC or a video camera.
  • Soldering of insulated wire for HDD or manufacturing of AV equipment, such as the DVD player, or home appliances.
  • Gang soldering of ground bar of ultra fine wire co-axial cable.
  • Heat caulking of lenses and circuit boards
