MetCal Connection Validation – The Next Generation of Soldering

Making solid connections between electrical components on a board is an important part of many hardware projects. A good solder joint forms an alloy at the surface of the PCB and the component lead. During soldering, a solder connection on a circuit board can quickly turn into a real...
