Metal post bonding using pre-fabricated metal posts

A method comprising:

• pushing a metal-post row to a capillary, wherein the capillary comprises a slot and a cutting edge at an end of the slot, wherein the metal-post row comprises a plurality of metal posts interconnected by weak portions;
• retrieving a metal post from the metal-post row, wherein the retrieving comprises cutting-through one of the weak portions that connects the metal post to a neighboring one of the plurality of metal posts, with the cutting-through performed using the cutting edge of the capillary;
• and
• bonding the metal post to a surface metal feature of a package component using the capillary, wherein the capillary is configured to move along with the metal post during the bonding the metal post.

A method comprising:

• pushing a metal-post row to a capillary, wherein the capillary comprises a slot and a cutting edge at an end of the slot, wherein the metal-post row comprises a plurality of metal posts interconnected by weak portions, wherein the metal posts are bent to have zig-zagged shapes;
• retrieving a metal post from the metal-post row, wherein the retrieving comprises cutting-through one of the weak portions that connects the metal post to a neighboring one of the plurality of metal posts, with the cutting-through performed using the cutting edge of the capillary;
• and
• bonding the metal post to a surface metal feature of a package component using the capillary.
