What is a fundamental requirement for component lead orientation according to IPC-A-610?

The fundamental requirement for component lead orientation according to IPC-A-610 is that leads must be correctly aligned to ensure reliable solder connections. Proper alignment is crucial because it affects the quality and integrity of the solder joint. When leads are correctly oriented, they can make a proper connection with the pads on the printed circuit board (PCB), which enhances the reliability of the assembly and reduces the risk of defects such as cold joints or incomplete soldering.

Ensuring that leads are oriented correctly supports proper heat transfer during soldering, which is essential for achieving strong mechanical and electrical connections. This also helps in maintaining the correct dimensions and positions of components, contributing to the overall functionality and performance of the electronic assembly.
