Abstract
The utility model discloses a printed circuit board with a stamp hole structure, which is formed by splicing a plurality of single plates. Gaps are arranged between the single plates and between the single plates and craft sides, and connection plates are connected between the single plates and between the single plates and the craft sides. Each connection plate is connected with the single plates or the craft plates through two groups of stamp holes. The two groups of stamp holes are arranged at the connection positions between two sides of the connection plates and the single plates or between the two sides of the connection plates and the craft sides respectively. The hole diameter of the stamp holes is 0.2 to 0.5 mm, and a distance between the stamp holes is 0.4 to 1 mm. The utility model further discloses an electronic terminal, which comprises the single plates divided from the printed circuit board. The printed circuit board adopts the stamp holes with smaller hole diameter and hole distance, and burrs are smaller after board division so that negative effects of the burrs on assembling are reduced. In addition, board division can be conducted through a board division machine by adjusting the width of the gaps. The electronic terminal adopts the single plates divided from the printed circuit board so that the burrs are smaller, and effects on the assembling are small.
