Circuit board segmentation type flying probe test unit and test method

The invention discloses a circuit board segmentation type flying probe test unit and a test method. The circuit board split type flying probe testing unit comprises a plurality of n flying probe testing machines which are located on the same horizontal line and connected in pairs, the flying probe testing machines are connected through a horizontal conveying device which moves horizontally, and the horizontal conveying device is used for conveying a circuit board with the length of m of the first flying probe testing machine entering the flying probe testing unit to the first flying probe testing machine; the flying probe test modules pass through n flying probe test machines in sequence, and each flying probe test module is arranged between (m/n) * (x-1) and (m/n) * x of the length of the inner closed plane and is used for testing the length of the circuit board between (m/n) * (x-1) and (m/n) * x. According to the circuit board split type flying probe testing unit, split type testing of one circuit board ca
