Mobile phone power adapter PCBs<\/strong> are getting smaller every year. Faster charging requirements, adoption of GaN technology, and more compact product designs are pushing components closer together than many manufacturers expected a few years ago.<\/p>\n\n\n\n

On paper, the design looks efficient.<\/p>\n\n\n\n

On the production floor, it often creates a different discussion.<\/p>\n\n\n\n

Engineers start noticing small but frustrating problems:<\/p>\n\n\n\n

Cracked solder joints.<\/p>\n\n\n\n

Damaged edge components.<\/p>\n\n\n\n

Micro-stress around sensitive ICs.<\/p>\n\n\n\n

Unexpected yield drops.<\/p>\n\n\n\n

And sometimes the depaneling process becomes the last place people investigate.<\/p>\n\n\n\n

The issue is that power adapter boards are no longer simple rectangular PCBs with large empty margins. In many cases, components sit only a few millimeters\u2014or even less\u2014from the board edge.<\/p>\n\n\n\n

A separation process that worked perfectly in 2022 may not be sufficient in 2026.<\/p>\n\n\n\n
