How Does Rework Station Works?

Since soldering joins important components, it requires high professionalism for quality work. A good solder joint should be smooth, concave shape and shiny. The joint should be at 40 to 70 degrees. If soldering is not done well, the customer of the product suffers the consequences. Rework stations help to deal with the soldering joint issues, faulty components, solder bridges, and upgrading or changing parts. Professionals well as people who are new to soldering make soldering issues. Soldering joint issues are among the leading issues that are sorted out in a rework station. The

rework station price in India for various soldering issues is affordable so you do not have to worry about inaccurate soldering joints.

Overheated Joints

Sometimes heated solder fails to flow and this leads to overheated joints. You need to be very careful when repairing the joint because the residue from the burnt flux can be problematic to deal with. Use isopropyl alcohol or the tip of knife and a toothbrush to remove and dust away the flux residue. To prevent overheating during the repair session, clean the joint and keep the iron tip hot and clean.

Disturbed Joints

After soldering, you should leave the surface undisturbed so that the joint can cool down properly. If you move the component before the joint dries out completely, the joint appears rough or frosted. This is called a disturbed joint.

A disturbed joint can be repaired in a rework station. Preheat the solder at the disturbed joint then leave it to cool without disturbing it. If you need to stabilize the board, use a vise.

Insufficient Wetting Pin

This occurs where the solder wets the pad and does not wet the pin. This happens when insufficient heat is applied to the pin and the solder fails to flow well. You can correct the situation by using more solder to the surface. Make sure that the solder iron tip touches the pad and pin when soldering. To prevent the problem from happening again, heat the pin and pad evenly.

Cold Joints

You should ensure that the solder melts completely to avoid the formation of cold joints. The joint is usually rough or looks like a lumped surface. If the joints are not repaired, they crack with time as they are very weak. In most cases, the joints have excess solder so you may need to draw out some of it.

Since the joints are weak, you should repair them to make them efficient and strong. Heat the solder again until it starts to flow again. Remove the excess solder before it starts to cool down. Ensure that the soldering iron is well heated before using and have some warm up time as strategies for preventing cold joints.

Excess solder

The joint results from using too much solder. The solder is incapable of wetting the pad or pin thus leading to an unreliable soldering. Use a solder sucker to remove the excess solder after melting it.

If you solder a lot of components, why not some up with a work station to help you correct any soldering mistakes?
