Solder reflow requires strict temperature control to get the needed tight joining. Infrared heat is ideal for the reflow process because:

• IR allows you to target exactly the area you want the solder reflow to occur.
• Infrared heat also offers the advantage of being essentially instant on and instant off, saving energy.
• Infrared solder reflow can be performed in an oven that allows multiple zones individually controlled for temperature.
• With IR, solder reflow is fast, as much as six time faster than other kinds of heat.
