Drag Finishing of Delicate Parts

For complex parts with high surface finish specs, production deburring and surface prep can be done using the drag finishing process whereby the parts to be deburred and finished are mechanically dragged through the media while attached to fixtures—thus preventing the parts from contacting one another.

Investigation of Tin Whisker Formation

Immersion tin and lead-free hot air solder leveling (HASL) coatings based on SnCu or SnAgCu alloys are widely used as surface finish materials for printed circuit boards (PCB). These coatings prevent the underlying copper from corrosion and preserve its solderability during lead-free assembly processes and for a long storage life of PCBs.
