A pick and place machine (30) having morphing vacuum tip (10) comprises a chamber (24) having a sealed first port (25), a filter (22) on a second port (27), and a vacuum (12) on a third port (23), a needle (28) pierced through the sealed first port and through the filter on the second port, wherein a vacuum (14) is placed on the portion of the needle piercing through the sealed first port. Finally, the morphing vacuum tip additionally comprises a non-porous bag (18) having a plurality of fine particles (16) within the bag and an external portion of the bag surrounding a periphery of a portion of the needle pierced through the filter on the second port, the non-porous bag having an open portion being exposed to an external side of the filter on the second port of the chamber, wherein the vacuum on the third port sucks air out of the non-porous bag and the filter prevents the plurality of fine particles from entering the chamber.
