Selective Solder Paste Printing for BGA Components
Could we print paste only on the pads that have functional requirements? Could we skip printing on 50 or more of the interior pads since they serve no function? The Assembly Brother, Phil Zarrow and Jim Hall, discuss this topic and share their own experiences.

Continuous Improvement: The Task That Never Ends in the Cleaning World
The job of a cleaning agent is to remove an unwanted contaminant, or simply some kind of “dirt”. How can you efficiently remove that soil while minimizing total waste and improving worker safety? While that answer evolves based on updated impact studies and new regulations, the goal of removing those undesired contaminants remains fixed.
