What is a reflow furnace?

and Reflow Pec is an electronic heating device that is used to install electronic components on plates with circuits (PCB) through surface mounting technology (SMT). This technique is widely used in the electronics production industry because it allows for easier construction of electronic devices. There are several types of reflow furnaces. They are helpful to ensure that the electrical components are properly mounted and that the electrical connection on the circuit board is provided by soldering techniques.

Surface assembly technology is the preferred technology in electronics because it is cost -effective compared to other techniques such as processes through the opening. Although it is possible to solder most of the SMT components manually, it is very time consuming, because each component must be soldered individually. This problem was solved by the invention of the reflow furnace.

Refrow oven allows the user to control the temperature, so far healing of printed joints and soldering together with the soldering waistthat. To experience a good reflow, thermal profiling must be set systematically. This is done first by preheating the oven to ensure that the PCB temperatures are hot enough to dry the solder paste. Immediately after reaching thermal stabilization, the PCB board heats up rapidly and at the same time ensures that the PCB temperature is higher than the reflow.

Infrared and reflow convections have more zones and their temperatures are checked individually. Each zone consists of several sub -zones for heating and cooling. The source of heating consists of ceramic infrared heaters and heat is transmitted by radiation.

steam steam is another type of reflow furnace that heats the PCB plate with thermal energy. This energy is derived from the phase change of the heat transfer liquid that condenses on the PCB. The choice of liquid to be used in the oven is generally determined by the preferred boiling point in the soldered alloy placed in the ovenwould be.

For circuits that require quick heating and cooling, an industrial reflective oven is used. The faster the heating process is completed, the less thermal voltage is placed on the components. These furnaces are generally used in situations that revolve around very large plates with circuits.

Many fans often decided to build their own furnaces. These reflow furnaces are often made of household appliances such as microwave furnaces that use infrared rays as a heat source. One of the disadvantages of the domestic furnaces is that the cooling process is difficult to implement.
