Leading Benefits Of Liquid Soldering For Printed Circuit Boards

With how widespread soldering has become, many techniques have been developed to achieve a good solder bond. These techniques include the use of many materials and alloys and employ several methods to achieve a good, reliable bond on a chip or printed circuit board. The secret to achieving a good solder bond lies in selecting the right soldering materials from the get-go. In this article, you will learn about the leading benefits of liquid soldering for printed circuit boards.

What is liquid solder?

Liquid solder is the common name given to the technique used when the flux employed is water soluble. The flux is available in packages which can be dissolved in a suitable quantity of water to obtain a flux that has high flowage.

Benefits of liquid solder for printed circuit boards

There are amazing conveniences and benefits associated with liquid solder fluxes that one should be aware of:

• Fluxes only have one purpose on a printed circuit board – to clean it of all the dust, dirt, debris and oxidation. If soldering is done on an improperly cleaned printed circuit board, it could lead to the lessening of the board’s life, malfunctioning devices, short circuits, etc. Therefore, it is necessary that printed circuit boards are cleaned effectively. Liquid fluxes fulfill their purpose in the best way possible. They have a right amount of activity, which makes them readily react with any impurity present on the board and leave behind a clean, oxidation-free surface to work upon.
• Liquid fluxes have excellent wetting properties. It is because liquid fluxes are dissolved in water, that gives them a proper flowage over the entire circuit board. Liquid fluxes reach every nook and cranny on the board, not leaving even the minutest of crevices un-wetted. This is the primary reason why liquid fluxes are widely used.
• Liquid fluxes, being dissolved in water, typically never burn during soldering. This is an excellent property for a flux considering all the residue and soot that gets left behind by their pasty counterparts.

Liquid fluxes may require thorough cleaning under pressure after usage, but all the benefits listed above far outweigh this minor inconvenience.
