production eyeletting of component leads
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 ? |

production eyeletting of component leads
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. |

I always thought that the eyelets were pressed into and possibly swaged to the board instead. ?-) |

IC socket pins , turned or sprung, have location wells to assist this, but eyelets don't |
