A Ball Grid Array (BGA) electronic component

May 7, 2010
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.
