Mill-Max Offers Swage Mount PCB Pins for Interconnect Applications

/in , /by

Oyster Bay, NY, June 13, 2017 – Mill-Max is adding to its diverse mix of swage mount PCB pins with six new offerings designed for interconnect applications.  These swage mount terminals are designed to be mechanically fastened to a board or panel and plugged into sockets or soldered into mating boards in board stacking and other interconnect configurations.

Swage pins are often thought of as wire-to-board soldering terminals and test points or as hardware such as PCB standoffs, but they are also an excellent choice for board-to-board interconnects.  They are cost effective due to their simple design, don’t require the more precise PCB hole specifications associated with most press-fit pins and can be processed in volume with semi-automatic or automatic equipment.  Swage assembly is a method of mechanically fastening pin terminals to a circuit board, similar in style to riveting.  After the pins are swaged, they are soldered, providing a robust mechanical and reliable electrical connection.

PR673The swage pins featured here are offered in various diameters and lengths to suit a wide variety of interconnect applications.  They are useful when space is limited, near the edge of a board for example, where a connector with its housing is not an option.   The swaged pin takes up relatively little space and is secure without the need of an insulator.  The longer pins are perfect for overcoming the height of taller board components (large capacitors, transformers, power supplies, potentiometers) to connect to a daughter card or other module, while the low profile 4658-0 may be used on boards which are primarily SMT, to keep the overall stacked board assembly height to a minimum .

All the pins are high speed precision turned from brass alloys and annealed to prevent cracking during the swaging operation.  The standard plating for these pins is matte tin over nickel with other plating options available upon request.

MillMax – Target Connector Lineup Expanded with .050″ and .100″ Concave Face Right Angle, HSMT and More

/in , /by

Mill-Max is expanding its selection of target connectors in both our .100″ (2,54mm) and .050″ (1,27mm) grid families. Target connectors are used in place of SMT pads on a PCB as the mating surface for spring-loaded pins. The new series include right angle with concave mating face (.100″ grid), through-hole and surface mount with concave face (.050″ grid) and horizontal surface mount and right angle (.050″ grid) with both flat and concave face options available.

Combining target connectors with spring-loaded connectors on opposing boards can be a simple and convenient solution for making connections between stacked boards or docking stations and devices.

As a complement to our existing .100″ grid right angle target connectors, we are introducing two new series featuring targets with concave faces. The single row series is 399-10-1XX-10-007000 and the double row is 499-10-2XX-10-007000; both are for through-hole mounting.

In our .050″ grid lineup, we have added concave face versions of our SMT and through-hole target connectors: 856-10-0XX-10-002000 (single row, through-hole); 856-10-0XX-30-002000 (single row, SMT); 857-10-0XX-10-002000 (double row, through hole); 857-10-0XX-30-002000 (double row, SMT).

Concave face target connectors provide additional surface area for mating and can aid in centering/alignment of components and/or boards fitted with spring-loaded connectors.

Rounding out the lineup of new target connectors are right angle and horizontal surface mount (HSMT) versions on .050″ grid. These connectors provide low profile options for parallel or right angle board mating arrangements. The HSMT version is especially suited for daisy chaining applications such as those found in LED strip lighting assemblies. These connectors will be available with both flat and concave face options. The right angle series are 856-10-0XX-20-001000 (flat face) and 856-10-0XX-20-002000 (concave face); the HSMT series are 856-10-0XX-40-001000 (flat face) and 856-10-0XX-40-002000 (concave face).

All the pins are precision-machined and gold-plated for environmental protection, durability and reliable conductivity. The connector insulators are molded from high temperature plastic suitable for most soldering processes, including RoHS environments. All of these products are RoHS compliant.

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.
