The hot bar Welding, pulse heat units are designed to solder electric components. These systems consist of a reflow head which holds the object and applies pressure and force while the pulse heat power supply then uses the current.
Pulse heating is an instantaneous heating method. Electric current is released from the power supply and then applied to a heater tip. The heater tip heats ups by resistance, and the heat then melts the solder. When the solder has melted, the current is turned off, and the solder is cooled. Once the solder has cooled completely, the heater tip raises up away from the workpiece.
This creates highly reliable joining without Solder Reflow applies and maintains pressure on the workpiece until the solder hardened. Constant pressure allows for the pieces to set before the head releases pressure.
We offer multiple pulse heat power supplies, various reflow heads, and many different heater tips. Contact us to further discuss your specific requirements.
Advantages of the hot bar pulse heat systems:
- This method is most suitable for reliable soldering and thermo-compression bonding because heating and cooling are done while applying pressure
- Good repeatability of heating temperature and time requires no skilled workers
- Partial heating in short time allows reducing thermal damages
- Great for working with lead-free soldering

Applications for Hotbar – Pulse Heat Unit:
Hot Bar Reflow System Features:
High Reliability Joining – Because heating and cooling takes place while the pressure is being applied, the work position is not shifted during joining.
Variable Temperature Profile – Because the heating is local and instantaneous, thermal impact to the peripheral components is restrained.
High Reproducibility – Digital PID control enables good reproducibility of temperature and time. As a result, no skill of the operator is required
Pb Free Compatible – Pb free solder is accommodated by setting to high temperature and long heating time
User Interface – RS-232C&I/O is standard equipped, making the unit easy to be connected to external equipment such as incorporating into an automated system
Ample Monitoring Functions – Temperature monitoring: Upper and lower limit (average, peak), Profile detection error: Over-heat, Thermocouple disconnection, etc
Other Standard Functions – Number of stored settings: 15, Head vertical and cooling air control signal, Auxiliary thermocouple input, Counter function
