Target discs expand diameter and height options

These low-profile SMT disc-shaped terminals, now available from distributor Digi-Key, suit applications where vertical space is at a premium.

The series include the 1593-X, 1618-X, 1625-X, and 1656-X SMT discs, with diameters of 0.093in. (1.98 mm), 0.118in. (3 mm), 0.125in. (3.18 mm), and 0.156in. (3.964 mm), respectively.

Each series is precision machined from brass and comes standard with a 10 µ” hard gold finish with a nickel under-plate and is available in four heights from 0.025” (0.64 mm) to 0.055in. (1.4 mm) in 0.010in. (0.254 mm) increments.

Custom sizes are quickly and easily achievable via Mill-Max’s high-speed precision-machining processes.

Other plating options, such as thicker gold or other materials, are also available.

With flat surfaces on both sides, target discs 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.
