概要（Overview）

The a3Di is a new inspection tool designed and built in Great Britain by Amfax Limited. This innovative 3-Dimensional laser metrology system accurately profiles a PCBA and all of its components to validate the completed assembly against the 3D CAD design model. The a3Di system is unaffected by component types, PCB color, lighting, height, position or board warpage ensuring accurate and repeatable measurement inspection results with near zero false calls. Interested in taking your printed circuit board assembly operations to the next level of quality? The a3Di utilizes absolute 3D measurements to inspect your PCBA’s. Metrology precision in PCBA inspection can help you eliminate process defects; defects you might not know are there. While the a3Di finds more true defects, its precision and measurement based programming limit false calls and the need for human intervention. The a3Di provides extensive process data to feed an SPC system the information required to quickly verify and validate that your assembly operations can pass a customer quality audit with minimal data collection effort. Quality processes start with accurate inspections. a3Di inspection programs are generated from CAD (ODB++ files), they are typically debugged and green-lighted in a few hours. If all of component models are resident in the a3Di library, then programming can be completed in less than 1 hour.
