I've never been in production but its easier to align eyelets singly onto
pins of an IC or in this case socket than try to align all 16 pins of an IC
into pin sized holes in eyelets already in an array in a pcb. IC socket pins
, turned or sprung, have location wells to assist this, but eyelets don't
