System for placement of circuit panel having interconnected board units

A board placement system for a printed circuit board having multiple interconnected printed circuit board units, comprising:

• a reference platform including a work surface and an opening formed in said work surface;
• a micro-adjusting unit provided within said reference platform, and including a micro-adjusting table, and a support seat which is disposed on said micro-adjusting table, which is located within said opening, and which is flush with said work surface, said micro-adjusting table being capable of bringing said support seat to move and rotate relative to said work surface;
• a measuring unit disposed on said reference platform and including a camera for measuring planar precision, and a laser for measuring levelness;
• and
• a computer device connected electrically to said micro-adjusting unit and said measuring unit, and capable of driving said measuring unit to move along a predetermined work path.
