prescored
Prescored Eyelets for printed circuitry are prescored at equally spaced points on the barrel ID, so as to cause uniform splitting to (but not below) the printed circuit pad. They permit a unique soldering sequence as a single pass over a wave solder machine causes solder fillet to be formed on both sides of the board. Manufactured from oxygen-free, high conductivity copper, they can be supplied with any standard electroplated finish.
