  • Pre-screening, compliant pin guiding and quality monitoring press-fit apparatus
    Patent number: 11050208
    Abstract: A compliant pin pre-screening, guiding and quality monitoring apparatus is provided. The compliant pin pre-screening, guiding and quality monitoring apparatus includes a fixed plate, a movable plate, a printed circuit board (PCB) and a press-fit connector. The fixed plate defines a through-hole and is disposable above a working table. The movable plate is disposable to be urged by a bias against a first surface of the fixed plate facing the working table and includes pin extendable through the through-hole. The PCB defines a via and is disposable on a second surface of the fixed plate opposite the first surface whereby the pin is extendable through the via with the via corresponding in position to the through-hole and the pin. The press-fit connector is disposable to be secured in position proximate to the PCB and to be inserted into the via with guidance provided by the pin against the bias.
