Hot Bar Soldering

Hot bar reflow soldering is a selective soldering process where two pre fluxed solder coated parts are heated using a heating element called a thermode or a hot bar to a sufficient temperature to melt the solder.

Hot bar soldering in this method resistance soldering a heated stamp also cal led bar or thermode is pressing with an adjustable programmable force on the two parts to be joined one lying on top of the other. The temperature of the stamp transfers the required heat into the joint to be soldered.

Low voltage high amperage electricity is run through a metallic thermode that is designed to have higher electrical resistance along the soldering face. Design tips for successful hot bar reflow soldering. The electricity heats the thermode face to a predetermined temperature.
