Mill-Max Manufacturing Corp. Inc. expands its family of spring pin mating products, with four new series offering additional diameter and height options. These low profile SMT disc shaped terminals are perfect for applications where vertical space is at a premium.
The expanded series include the 1593-X, 1618-X, 1625-X, 1656-X SMT discs, with diameters of 0.093 in. (1.98 mm), 0.118 in. (3 mm), 0.125 in. (3.18 mm) and 0.156 in. (3.964 mm) respectively. Each series is precision machined from brass and comes standard with a 10 u in. hard gold finish with a nickel under-plate and is available in four heights from 0.025 in. (0.64 mm) to 0.055 in. (1.4 mm) in 0.010 in. (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.
