Abstract

The embodiment of the invention relates to the technical field of electronic equipment, in particular to a printed circuit board and an intelligent terminal. The printed circuit board comprises an insulation substrate, and the insulation substrate is provided with a function test wire, test points and cursor positioning points. At least one cursor positioning point is electrically connected with the function test wire. According to the printed circuit board, the number of the test points is reduced, so that the area of the printed circuit board is reduced, and the intelligent terminal comprising the printed circuit board meets the requirement for being thin.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of electronic equipment, and in particular to a printed circuit board and an intelligent terminal. Background technique [0002] Printed Circuit Board (PCB) is the carrier of all electronic products. It installs various integrated circuits, components and connectors, and is interconnected by multi-layer wiring to form various electronic components. [0003] With the increasing automation of the smart terminal manufacturing process, more and more test points need to be set on the printed circuit board to detect the product yield of each production step in the manufacturing process. In addition, the printed circuit board also needs to include multiple cursor alignment points (Mark points) to meet the requirements of Surface Mounted Technology (SMT). In order to cooperate with the production and use of test fixtures, the size and spacing of each test point must meet certain requiremen...
