The feasibility of high-volume microminiature component manufacturing using Type 5 and 6 pastes.
Once a bitter foe of the West, the Southeast Asian nation has become a haven for electronics manufacturing.
Scanning multiple depths at once saves time and gives more accurate data at each depth.
A JEDEC tray filled with components of a single type is moved onto the stage of an automated acoustic microimaging system. The transducer begins scanning the tray, pulsing ultrasound into the components thousands of times a second and receiving the return echoes. Analysis of the echoes will identify components having internal anomalies that disqualify them from use. At the end of the line, those components will be removed.
A printing investigation revealed unexpectedly stable and adequate paste transfer levels for metric 0201 components.
