SOLDER: WHAT IS IT AND HOW TO USE IT

Electronics are the stars of this time and age. Daily routine seems impossible to go through without the everyday conveniences that various electronic devices make possible. The electronics industry today is one of the most thriving and happening industries in the world. Thanks to a certain technique that makes it possible to develop devices that can do practically anything, now the populace can sit back and enjoy the fruits of all of it. This technology is soldering. In this blog, you will learn about this revolutionary technique and the soldering materials that have changed the way electronics are perceived in this world.

What is solder?
Solder is typically an alloy used to create an electrically conductive bond between two metals. This alloy makes fusing two metals possible by melting and connecting the two surfaces. In order for this bond to be permanent and efficient, it is necessary for the connection surfaces to be clean and free of oxidation. There are many types of soldering materials available in the market, so that you can choose the one best suited for your needs.

•    Lead solder – This solder is composed of tin and lead, and is one of the most commonly used solders out there.

    Flux-core solder – this solder is packed with convenience. It has flux material at its core so the users don’t have to apply it prior to soldering.

•    Hard solder – these solders are typically made from copper fused with either zinc or silver. This alloy melts at high temperatures and is used for brazing.

•    Lead-free solder – this solder is an alloy that was developed to be lead-free and environment friendly. These alloys are made up of bismuth, indium, coppers, silver, etc.

How to use solder?
Solders are usually available as coils of solder wire. After you have heated up and cleaned the soldering iron, touch the solder wire to the tip of the iron and tin it – it helps achieve a better soldered joint. One can also find solder spheres in the market. To use solder balls, you need a stencil and flux paste. Alternatively, you can employ BGA JIG that already have embedded solder balls. If any of the above solder use is not suitable for your process, you can also employ fully automated machinery.
