These pillars serve multiple functions: they transfer heat from high-power components to cooling systems, reducing operating temperatures by 20-35\u00b0C; they strengthen the board&#8217;s structure to prevent solder joint failures in high-vibration environments; and they provide electromagnetic shielding to protect sensitive signals.<\/p>\n\n\n\n<p>Manufactured with precision laser drilling, the pillars maintain tight height tolerances within \u00b10.05mm.
