摘要

PURPOSE: A circuit board having an inspection coupon is provided to reduce an inspection time by inspecting a circuit pattern of the circuit board using the inspection coupon, thereby improving productivity of the circuit board. CONSTITUTION: A circuit pattern (12) is formed on a board area (10). A dummy area (20) is extended from the board area and is formed. One or more inspection coupons (22) are formed in the dummy area. The inspection coupon comprises multiple line patterns. The inspection coupon is formed into a shape which is similar or equal to a part of a micro-pattern among the circuit patterns.
