What kind of flux should i use

In addition, water soluble flux tends to be a more aggressive oxidizer than is usually required. Organic flux is more reactive than rosin activated flux and is thus a stronger cleaner. Note: You can also find inorganic water soluble flux, which is even more powerful than water soluble flux. No-clean flux is a mixture of organic resins — aside from rosin — mixed with certain inorganic agents. The behaviors and properties of no-clean fluxes can vary significantly depending on their respective chemical composition; for example, some no-clean fluxes leave a tremendous amount of residue, which is unattractive, though it is no threat to the surface.

George Leger has a Masters in Electrical Engineering from Stanford University, worked in private industry pioneering surface-mount technology and in government research labs for twenty years, published several papers on surface-mount technology, co-authored papers published in national symposiums on accelerator technology, was past president of SMTA and an adjunct professor at the community college level, holds a patent, and is a certified microchip design partner, serving as a consultant to many companies developing electronic circuits.

Some detergents can also be compatible with the type of flux you have. Thus, you need to check the specifications of flux. My hobby is electronic circuits and soldering irons. Alloys containing less than a quarter of chromium and nickel are easy to fuse. Moreover, these alloys can create strong bonds with other metal elements, excluding aluminum and magnesium.

Understanding the process and preparation Remember that some nickel-plated alloys can form carbides…. Being an owner of SolderingIronGuide and a soldering semi-expert for many years, I know for sure that irons are so hard to maintain.

People who are new to soldering usually neglect the maintenance of their irons, though it is an obligatory thing to do. Why do…. When you are soldering two wires together, it is essential to know the proper way to hold a soldering iron. If you do not have the correct grip on the tool, then there is a higher chance that your connections will come undone or create an electrical short circuit.

This article will teach you how…. Since a voltage regulator offers a controlled and steady voltage for the microprocessor, you may power Arduino Nano in two ways: Mini USB cable: The USB cable is the most common and therefore the simplest way to power the Arduino Nano board. Thanks for sharing the content. Soldering flux is actually activated with the help of the heat of the soldering operation to remove the last layer of oxidized metal so that the solder will wet the base metal and produce a good joint.

Glad to learn about the application of flux on soldering electronics. Thanks for sharing the blog Tom. Can you help me? When we perform soldering process finish, our gold surface is deformed.

Do you know some reason for this problem? Hello, Thuan! Once the solder has flowed along the joint, and the metal surfaces have been heated sufficiently to join together, turn off the torch and let the gold cool. After a couple of minutes, quench it further in the water bath. Use copper tools to lower the gold slowly into the pickle bath, and wait a few minutes for most of the discoloring fire-scale on the surface to be removed.

Remove the gold from the pickle, rinse in the water bath, and inspect. You may need to polish or file off excess solder or fire scale to achieve the appearance you desire. When we do soldering process, the gold layer is deformed. Please advise me for this. Many thanks. Thanks for showing how to use flux when soldering electronics! Soldering flux is activated by the heat of the soldering operation to remove the last layer of oxidized metal so that the solder will wet the base metal and produce a good joint.

Universal advice for buying a flux agent for electronics: eventually, the major thing to remember is that the least aggressive i. Such an additional layer during a soldering job will make sure that oxides are under the control and form a great bond. The SRA Rosin Paste Flux is offered in a small container holding 2-ounce flux to complete all of your soldering applications.

Water-soluble flux provides good soldering results because they have good flux activity. They have good wetting action ability to remove oxides and prepare a clean surface for soldering. However, they may be too aggressive, calling for extra precaution during cleaning of the PCB Assemblies to avoid flux contamination.

The main function or use of flux in any Printed Circuit Board Assembly or rework is to clean and remove any oxide and impurities from the board. These oxides deposited on the board may not permit good solder joints.

If the solder joint is poor, there will be poor electrical conduction or poor flow of electricity through the circuit. Solder flux helps to de-oxidize metals copper tracks on the PCB and leads of electronic components and helps better soldering and wetting. The activators in the flux promote wetting of the molten solder to the surface mount lands and component terminations or leads by removing oxides and other surface contaminants. Alpha Cookson trusted manufacturer and supplier of all types of solder flux.

Several factors determine the type of flux to be used during soldering:. After the soldering process is over, it is important to clean the board to remove any unwanted flux residue that can affect the performance of the board and can even cause electrical short circuit. In case of fluxes that need cleaning after soldering, solvent cleaning or aqueous cleaners can be used.

Most soldering flux manufacturers and vendors also supply flux cleaners.
