The Importance Of Reflow Soldering Oven

By Alyce Powell


Reflow soldering oven is one way to attach more than one electrical components to work on the contact pads with the use of the solder paste. This paste is usually a sticky substance which is a mixture of the powdered solder and flux. The whole thing is subject for good control which can melt and connect the full joints.

Heating is accomplished by passing the assembly throughout the reflow oven or under the lamp or by soldering each joint using a hot air materials, in most cases, it is a pencil. The soldering is the most common technique to attach the surface mount to the circuit board. You can also fill the holes with the paste then insert the materials through the paste.

You must practice how to do a wave soldering which is simpler and actually cheaper. This is not only for doing pure hole boards. When you choose to use the boards which contain the full mix of ever component, the process will eliminate all the problems while doing the assembly. It can also minimize the cost of the assembly.

The goal is to melt the solders and then heat all the adjoining surfaces. You can do it without trying to overheat and then totally damage the electrical tools. During the process of soldering, it will undergo several zones and the most common are recorded. These are called zones because each one has its own unique profile.

In the first zone, the maximum slope can be the relationship between time and temperature. It can also measure how fast it is on the PCB or know as printed circuit board. The zone is the longest procedure thus it has its corresponding rate. Avoid any type of damage by exceeding the rate of the slope.

The second is the thermal zone which is usually where the exposure happens. It is the period of removing the solder paste and then activates the flux. It is where the components begin to undergo oxide reduction on the leads and pads of the components. Having too high temperature can lead to oxidation of the paste and the termination of the components.

Then comes the process where it reaches its maximum rate. The important consideration to remember is the maximum temperature which will allow to undergo the whole process. Its limit is fully determined in the assembly. This is being recommended for the monitoring and keeping up the process.

The cooling zone is to gradually cool the processed board and then solidify all the solder joints. Proper cooling gives thermal shock to every component. The fast cooling rate is selected to have a fine structure that has a good quality unlike the others. The parameters being used must be considerable enough to analyze the results.

The discussed points are only few of the major considerations to be made to realize how important the reflow soldering oven is. One must do it correctly to avoid any type of potential problem that can happen anytime. To assure the safety, you must know what it takes to be safe. Avoid any regrets that you can have in the future. Make sure to do the correct method all the time.
