In circuit test adapter for circuit boards uses mirrors to steer UV laser beam to ionise fine channels to test points

摘要

An in circuit test adapter for circuit boards (8) uses mirrors (38) to steer UV (Ultraviolet) light (2) to ionise the air in fine conducting ion channels leading to the circuit board measurement points (41, 44) for contactless current transmission from signal source with the charge carrier set in motion through charged electrodes.
