Would you like to learn how to solder wires to different types of “terminals” (contacts)? PIEK has developed a practical course in which the different types of terminals are discussed, how to swage/mount terminals into the printed circuit board, how [...]
Drag soldering is soldering with a hollow soldering tip (mini wave tip) or with a flattened tip (hoof tip), a drag soldering tip. Due to the surface tension (adhesion), a drop of tin (bead) remains in the cavity. You drag [...]
Last year, Piek showed the basics of hand soldering, and today we're taking things to a more fundamental level. We'll be talking about the right tools you’re going to need and how to choose them, as well as the proper care and [...]
