Mill-Max Offers Swage Mount PCB Pins for Interconnect Applications

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.

Mill-Max Introduces 3 mm (.118”) Maximum Stroke Spring-Loaded Pin

Mill-Max Introduces 3 mm (.118”) Maximum Stroke Spring-Loaded Pin

Mill-Max is proud to announce a new addition to its spring-loaded pin selection with the introduction of the 0919-0-15-20-89-14-11-0.  This new offering has a maximum stroke of 3 mm (.118”) with an initial height of .379” (9,63 mm).  It is designed for SMT termination and can be used at a minimum spacing of .100” (2,54 mm).

The 0919 spring pin has a recommended working travel range of .030” (0,762 mm) to .100” (2,54 mm) and a maximum mechanical travel of .118” (3 mm), the greatest in our current spring pin lineup.  There is a hard stop incorporated to prevent over compression and minimize the risk of damage to the spring.  This pin is ideal for applications where greater compliancy is desired.  It can compensate for problematic tolerance stack ups in assemblies featuring board-to-board or device-to-board connections.  The 0919 allows a greater range of movement between mating components, providing stable connectivity in assemblies subject to motion, such as mobile devices and light weight devices that often use more flexible housings and materials.  When compressed to mid-stroke, it still allows for .040” (1,02 mm) additional travel while remaining in the recommended working range.  Because the 0919 has more stroke capability, it provides higher forces at its recommended working travel than similar spring pins of this scale.  This may be desirable to a designer seeking to sustain reliable contact during cycles of high shock and vibration.  The 0919 exhibits an average 85 gram force at mid-stroke with the ability to achieve 127 grams at the top of the recommended travel.

The 0919 is also available packaged in single and double row strips on .100” (2,54 mm) centers.  The single row series part number is 837-22-0XX-30-001101 (change last three digits to 191 for tape & reel packaging); the double row series part number is 839-22-0XX-30-001101 (change last three digits to 191 for tape & reel packaging).

Gold-plated brass components and stainless steel springs ensure the highest reliability, corrosion resistance and durability.  The spring-loaded plunger is suitable for mating with gold-plated PCB pads or Mill-Max target pins and connectors.

Mill-Max Expands its Line of Solder Cup Spring-Loaded Pins

Mill-Max is proud to announce a new addition to its spring-loaded pin selection with the introduction of the 0973-0-15-20-77-14-11-0.  This new offering has a solder cup designed to accept up to 20 AWG wire, has a maximum stroke of .080” (2,03 mm) and can be used at a minimum spacing of .100” (2,54 mm).

The shoulder and barb features are located and designed to allow easy and reliable assembly into connector housings. The terminating wires may be passed through a connector housing and soldered to the cup of the 0973.  Once the soldering is complete the wires can now draw the 0973 spring pins into the housing and the spring pins can be secured with the press-fit.  With the pins securely pressed into the housing, the shoulder acts as a stop, retaining the pins in the event the cable or wires are strained.   The shoulder will also prevent push out of the spring pin if the plunger end is over compressed.  These design features make the 0973 ideal for cable and bulkhead style connector assemblies.

The 0973 spring pin has a working travel of .040” (1,02 mm) and a maximum mechanical travel of .080” (2,03 mm).  There is a hard stop incorporated to prevent over compression and minimize the risk of damage to the spring.  The high retention force press-fit of the solder cup to the body of the spring pin insures the reliability of the component during soldering and assembly operations.

Gold-plated brass components and beryllium copper springs ensure the highest conductivity, corrosion resistance and durability.  The spring-loaded plunger is suitable for mating with gold- plated PCB pads or Mill-Max target pins and connectors.  For wire termination target pins consider Mill-Max 3024-0-01-15-00-00-03-0 and for connectors, see the single row 330-10-1XX-00-240000 and double row 430-10-2XX-00-240000.

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

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.
