Ball grid array electronic component

A ball grid array electronic component printed by electrostatic deflection of molten metal droplets


A Ball Grid Array (BGA) electronic component, printed via electrostatic deflection of molten metal droplets approximately 150 microns in diameter. Droplets were generated with capillary stream breakup. The array was printed in .14 seconds with an accuracy of (+/-) 12.5 microns.

This research was supported by grants from the National Science Foundation (DMII 94-57205 and DMII 96-22400). (Year of image: 1996)
