Low-Profile Target Discs

Mill-Max's 1578-X-57-15-00-00-03-0 SMT discs are 0.078" (1.98 mm) in diameter and available in four heights from 0.025" (0.63 mm) to 0.055" (1.4 mm) ±0.002" (0.0508 mm) tall. Employing precision-machining expertise, Mill-Max is able to achieve flat surfaces on both sides of the disc with virtually no burrs. The flat surfaces are ideal for surface-mount soldering and as the conductive mating surface for spring-loaded pins and connectors as well as test probes. The discs are typically placed on solder pasted PCB pads and then subjected to reflow soldering. Once soldered, the terminals are ready to be used as reliable, durable contact points.

The 1578-Xs are packaged on tape-and-reel 16 mm wide x 8 mm pitch, making them simple to integrate into existing pick-and-place equipment and assembly processes. The tape packaging is per EIA-481-D.
