The picture shows a cold solder joint. This is a defect for all product classes as described in IPC-A-610, J-STD-001, etc. The cause of this problem could be: Dirty/oxidized soldering tip Too little/no flux Incorrect soldering temperature Soldered too quickly [...]
Why do you need to clean a PCB after soldering? The flux residues that remain on the circuit board can cause short circuits. The picture shows what happens if you don't clean. This is a defect for all classes per [...]
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 [...]
