Abstract
An electronic carrier board is provided, including a carrier, at least two paired bond pads formed on the carrier, and a protective layer covering the carrier. The protective layer is formed with openings corresponding in position to the two bond pads. The openings are aligned in the same direction and expose at least a first sidewall and a fourth sidewall of each of the two bond pads. The first sidewall and the fourth sidewall are both perpendicular to an alignment direction of the bond pads. A distance between the first sidewall of at least one of the bond pads and a corresponding side of a corresponding one of the openings is at least about 50 μm greater than a distance between the fourth sidewall of the at least one bond pad and a corresponding side of the corresponding opening.
