production eyeletting of component leads

[N_Cook]

Are they just slid over the pins , relying on friction while
handling/placement and then at soldering it is assumed solder will get
between the lead and eyelet as well as between eyelet and pcb pad ?

Mark Bass amps (Italy) use no-name 0.25 inch input sockets (4 numeral molded
underneath and 3 pin holes each side of the body) . Eyeletted before
soldering but after desoldering with fresh solder, to aid pressed/eyeletted
removal , 2 of the pins have no wetting and dull finish other than solder on
the cut ends. One pin active , other pin just physical holding ,not
electrical, but eventually intermittant contact of the active one.

OK. I always thought that the eyelets were pressed into and possibly

swaged to the board instead.

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
