Abstract

The invention discloses a method for checking hole problems of a printed circuit board. The method comprises the following steps of checking when a pad is smaller than a hole; checking the deflection of a bonding pad; checking the hole of which the diameter is greater than or equal to the preset diameter; checking a non-circular hole or an octagonal pad; checking the hole metalizing; checking lead tin on a via hole; checking green oil on the via hole; checking jumper ID (identification); checking an embedded blind via. The method has the advantages that the hole problems of the printed circuit board can be automatically checked; the operation is simple, convenience and rapidity in use are realized, the response speed is high, the check efficiency is high, and the check accuracy is high.

Description

technical field [0001] The invention relates to the technical field of printed circuit boards, in particular to a method for checking hole problems of printed circuit boards. Background technique [0002] The printed circuit board software Altium Designer is an integrated electronic product development system launched by the original Protel software developer Altium, which mainly runs on the Windows operating system.
