  • Measurement system
    Patent number: 11204242
    Abstract: A measurement system is provided, including a measurement machine and a computer. The measurement machine is configured to measure a thickness T1 of a to-be-tested circuit board and a drilling depth D1 of the to-be-tested circuit board. The computer calculates a length S1 of a residual conductive portion in a back drilled hole of the to-be-tested circuit board according to a thickness T of a reference circuit board, a drilling depth D of the reference circuit board, a length S of a residual conductive portion in a back drilled hole of the reference circuit board, the thickness T1 of the to-be-tested circuit board and the drilling depth D1 of the to-be-tested circuit board.
    Type: Grant
