Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of flying probe testers, in particular to a two-wire needle holder for a flying probe tester. Background Art
[0002] A flying probe tester is an instrument designed for testing PCBs (printed circuit boards) with high-density component placement, numerous layers, high wiring density, and close test point spacing. It primarily tests the insulation and continuity of the circuit board. These testers typically utilize a "true value comparison location method" that provides real-time monitoring of the test process and fault points, ensuring test accuracy. Flying probe testers offer precise pitch, freedom from grid constraints, flexible testing, and high speed. However, existing test probes are prone to wire snags and damage due to their lack of elasticity. Existing pointed probe head components exhibit significant interference, a short service life, and difficulty in precise adjustment, resulting in low test accuracy. Therefore, we have redesigned a two-wire probe header for flying probe testing. Utility Model Content
