PALO ALTO, CA -- Agilent Technologies and the Advanced Development Group of Speedline Technologies are conducting joint research on the implementation of closed-loop process control for paste printing PCB assemblies. The research will use Agilent's post-print inspection systems and Speedline's Accela printer to measure process performance in Pb-free manufacturing.
 
Based on a recent joint Pb-free study, Agilent and Speedline determined that the positional accuracy of the paste deposit relative to the pad is a key element to ensure quality in fine-pitch and small-device Pb-free assemblies. This suggests that closed-loop process control could be advantageous for quality during the transition to Pb-free manufacturing.
