Resistance Reflow Soldering is a hot bar bonding process (thermo-compression bonding) in which heat is produced by passing an electrical current through either the parts which are to be soldered or through a thermode (reflow soldering tip) which heats the parts by conduction. The amount of heat produced and the force applied by the thermode are carefully controlled. The solder required at the joint is applied, in controlled amounts, in the form of solder paste, solder pre-forms, or by re-flowing the solder on pre-tinned parts. Flux or a cover gas is generally required for production line resistance reflow soldering, although some users report acceptable results without using either.
AIT has been the industry leading manufacturer of resistance reflow soldering thermodes and hot bars for the thermo-compression bonding industry for many years. Many customers find AIT because they are trying to save cost on consumable tooling, without sacrificing quality. AIT utilises a full climate-controlled inspection department to ensure high quality tools. AIT markets a product line of resistance reflow soldering tools and welding electrodes, but still over 50% of their business is in custom-designed tools for thermo-compression bonding applications.

Further Information
What are Reflow Soldering Thermodes
Reflow soldering thermodes, also known as hot bars, are precision heating tools used in resistance reflow soldering and thermo‑compression bonding processes.
They generate controlled heat and pressure to reflow solder at the joint interface, forming reliable electrical and mechanical connections in electronic assemblies such as wire‑to‑pad, flex‑to‑PCB, and fine‑pitch interconnects.
Key characteristics of reflow soldering thermodes include:
- Thermodes generate heat by electrical resistance and transfer it to the joint by direct contact.
- Temperature, time, and applied force are precisely controlled to ensure consistent solder reflow and joint quality.
- Thermode shape and material selection influence heat distribution, joint uniformity, and tool life.
- Reflow soldering thermodes are used in hot bar bonding applications requiring accurate, repeatable, and localised heating.
