Brazing and Soldering

Brazing is ideally suited for joining of dissimilar metals and is performed at relatively low temperature. But even a properly-designed joint can turn out imperfectly if the correct brazing process steps are not followed. These brazing procedures boil down the brazing process to six basic steps. There are six fundamentals of brazing that every brazer should follow to ensure consistent and repeatable joint quality, strength, hermeticity, and reliability. For the sake of simplicity, we'll discuss these six brazing process steps mainly in terms of "manual brazing," that is, brazing with hand-held torch and hand-fed filler metal. But everything said about manual brazing applies as well to mass production brazing. The same brazing process steps must be taken, although they may be performed in a different manner.

Soldering is a technique where a precisely focused laser beam provides controlled heating of the solder alloy leading to a fast and non-destructive of an electrical joint. The process uses a controlled laser beam to transfer energy to a soldering location where the absorbed energy heats the solder until it reaches its melting temperature leading to the soldering of the contact and this completely eliminates any mechanical contact.

Soft soldering using laser radiation is becoming more and more significant in the field of selective soldering techniques. Fast power controllability combined with a contactless temperature measurement to minimize thermal damage make the diode laser an ideal tool for this application. These advantages come into full effect when soldering of increasingly small parts in temperature sensitive environments is necessary. Laser soldering is a solution for applications that require selective solder joints such as connecting a circuit board to external terminals or for repair work.
