Einstein's photo-electric effect is the main physical phenomenon used in Laser Direct Testing technology.
When a high energy photon meets an electron in a metal pad, the electrons becomes excited, and can escape with residual kinetic energy.
Beamind's exclusive LDT technology not only drives away electrons from trace-ends but is also able to return them back to trace-ends.
Electrons movement means electrical current generation.
Beamind's unique LDT technology efficiently detects opens from this electrical current circulating through traces.
In this fashion, Beamind converts UV light from laser beams into electrical current in a full non-contact way to test IC Package substrates and other complex HDI PCBs for Opens & Shorts.
