Mill-Max Introduces Unique Low Profile SMT Target Discs

/in , /by

Mill-Max is excited to announce a new addition to its family of spring pin mating products. This low profile SMT disc shaped terminal is perfect for applications where vertical space is at a premium.

The new 1578-3-57-15-00-00-03-0 SMT disc is .078″ (1,98 mm) in diameter and only .055″ +/-.002″ (1,4 mm +/- 0,0508 mm) tall. Employing our precision-machining expertise we are 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 1578-3’s are packaged on tape & reel — 16 mm wide x 8 mm pitch, 4,000 parts per reel — making them simple to integrate into existing pick & place equipment and assembly processes. The tape packaging is per EIA-481-D.

These SMT target discs are machined from brass and come standard with a 10 u” hard gold finish with a nickel under-plate. 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. In addition, we offer many other styles of discrete target pins, which may better be suited to your application. As always, if you don’t see what you need feel free to contact our technical support team to discuss your particular application and requirements.

Additional Offerings of Straight and Right Angle Machined PCB Pins

Mill-Max has developed additional straight and right angle male PCB pins to complement the existing 35XX and 37XX series. In addition to the .020” (0,51mm), .025”( 0,63mm), .030”( 0,76mm) and .040”( 1,02mm) diameters available, these new pins now offer diameters of .060”( 1,52mm ) and .080”(2,03mm). They are suitable for plugging into receptacles and/or soldering into printed circuit boards. The new .060” (1,52mm ) and .080”(2,03mm) diameter pins are a good fit for applications demanding high mechanical strength or to meet higher current requirements.

The 37XX series is ideal for any situation where a right angle connection is required. They can be soldered on to a daughter card and plugged into receptacles or connectors on a motherboard for perpendicular board mating. They can also be combined with right angle receptacles or connectors to mate boards in parallel (daisy chaining). These brass pins are precision-machined and are closely monitored to produce pins with consistent bends each time. The tips of the pins have a full radius shape making them easy to plug into board holes or receptacles.

The straight pins, series 35XX, come in three lengths, .250” (6,35mm), .500”( 12,7mm ) and .750”( 19,0mm) and are available in diameters of .060”( 1,52mm ) and .080”(2,03mm).

The standard plating option is 10μ” gold over nickel. As always, other plating options are available upon request.
