A reflow oven is used for surface mount technology in electronics manufacturing. It allows for easier construction of devices and ensures correct fitting of components through reflow soldering techniques. There are different types, including infrared, convection, vapor phase, and industrial ovens. Homemade ovens are also an option but may have cooling difficulties.
A reflow oven is an electronic heating device used to mount electronic components on printed circuit boards (PCBs) through surface mount technology (SMT). This technique is widely applied in the electronics manufacturing industry because it allows for easier construction of electronic devices. There are several types of reflow ovens. They are vital to ensure that electrical components are fitted correctly and that electrical connections on the circuit board are secured using reflow soldering techniques.
Surface mount technology is the preferred technology in electronics manufacturing because it is cost effective compared to other techniques, such as through hole processes. While it is possible to solder most SMT components by hand, it is time consuming because each component must be soldered individually. This problem was solved with the invention of the reflow oven.
A reflow oven allows the user to control the temperature while heating the PCB and solder components together with the solder paste. To experience a good backflow, the temperature profile must be set systematically. This is done by preheating the oven first to ensure PCB temperatures are high enough to dry the solder paste. Immediately after achieving thermal stabilization, the PCB board is heated rapidly while ensuring that the temperature of the PCB is above the reflow.
Infrared and convection reflow ovens have multiple zones and their temperatures are individually controlled. Each zone consists of several heating and cooling sub-zones. The heat source is ceramic infrared heaters, and the heat is transferred by radiation.
A vapor phase oven is another type of reflow oven that heats the PCB with thermal energy. This energy is derived from the phase change of a heat transfer liquid which condenses on the PCB. The choice of liquid to use in the furnace is generally determined by the preferred boiling point of the solder being placed in the furnace.
An industrial reflow oven is used for loops that require rapid heating and cooling. The faster the heating process, the lower the thermal stress on the components. These ovens are typically used in situations revolving around very large circuit boards.
Many hobbyists often choose to build their own reflow ovens. These reflow ovens are often created by appliances, such as microwave ovens, that use infrared rays as a heat source. A disadvantage of homemade ovens is that the cooling process is difficult to implement.
