i3070 Series 5i Inline In-Circuit Testers (ICT) operates automatically without human intervention on the printed circuit board assembly (PCBA) manufacturing floor. The Inline ICT automatically loads and unloads the PCBA onto the In-Circuit Test fixture within the handler and the Pressor in the handler will push the board on the probes on the fixture to start test. To prevent the board get damage accidental due to improper alignment above the fixture, the alignment check can be enabled before the Pressor activates to push the board onto the probes on the fixture. There are several methodologies to check the board placement alignment, this application note describes a method using touchless laser sensor.
