  • Because there is no commonly accepted test of direct tensile strength for concrete, indirect tests must be made to guarantee the safety of roads, bridges and other concrete structures. Flexural…

  • Tensile strength tests determine how much of a pulling force you can apply to an object. You can observe how the object will stretch, and at which points it will show the most flexibility in…

  • Soldering and brazing are processes for bonding two or more pieces of heated metal together with a molten filler metal that forms an extremely strong bond. Flux is a chemical cleaner applied to the…

  • Without soldering, today's day-to-day life would be very different. Most types of consumer gadgets, including televisions, mobile phones, MP3 players and computers, contain electronic circuit boards…

  • Reflow soldering is a soldering process commonly used on electronics and computers. It employs solder paste comprising alloy powder and flux. Circuitry or other components are attached temporarily to…

  • Several methods are available to test soldered connections under different conditions. Solder ball/shear pull strength tests address grain coarsening in solder. Solder ball hot pull tests can focus…

  • Brother Intellifax 4100 is a fax machine with a number of surface mount LEDs used as status indicators. These LEDs can burn out with time, and it may be desirable to re-solder their equivalent onto…

  • When lead molecules in lead solder combine with oxygen molecules in the air the result is a dull gray to black tarnish that covers the surface of your soldering job. In many situations this isn't a…

  • New solder is generally bright and shiny, like a brand-new dime. Sometimes, however, you might not want your solder to look new. For instance, the appearance of a new soldering job can draw visual…

  • In the jewelry industry, silver and gold alloys are used to attach metals and stone holders to rings, necklaces and brooches. The following will guide you through using silver alloy to work on silver…
