Interface Modules

In the past two decades RS Tech has fabricated hundreds of different interface modules for a great number of test hardware applications.  With our vast experience we have found that even while serving a wide range of applications, interconnect modules tend to share similar design characteristics.  The photos on this page were chosen to illustrate some basic characteristics that modules share.

Specifying the appropriate contact mechanism is critical to a reliable product solution.  There are many contact forms to choose from in specifying the proper contact or contact combination to perform the job.  There are essentially two methods of making contact:  1) LIF (low insertion force) mechanisms such as receptacle or socket pins, typically used to mate peripheral hardware connectors or components to circuit boards.   2)  Spring probes or similar compression type contact mechanisms are typically used in board-to-board applications and the like.  One of these methods, or a combination of the two, must also be considered in creating a reliable and consistent electrical junction between the mated surfaces.

As you review the illustrations below do not impose boundaries or restrictions on your interface solution.  We fully understand the complexities of hardware interface. We can apply design and manufacturing techniques learned through years of experience to create your hardware solutions, however complicated it may seem.

RST has made a number of various interface ring assemblies.  While most requirements are for plastic bodies, we have made several high-performance rings and block assemblies using copper or aluminum bodies with insulator sleeves surrounding the contacts.  We have access to a vast library of spring probe contacts, in both single and double-ended tips, and an assortment of tip configurations to contact any surface. These products may be built in either ring or block configurations, as individual interface modules, or as fully integrated systems.  

RST makes an assortment of interface products using low insertion pins.  This photo illustrates a few of the many configurations possible in mating peripheral hardware to circuit boards.   
Illustrated here are a variety of male-to-female matched block and ring modules for quick and effective mating of integrated mother board to daughter card test systems.  RST also inventories the male and female pins (also shown in the photo) that are used with these assemblies. As a convenience to our customers, the modules can be ordered with or without the pins, such that either the modules or the pins may be ordered separately.   
RST has a full line of mini-sockets for plug-in components such as the Coto Relay and similar devices.  We carry many configurations in inventory and can offer quick delivery.  We handle custom requirements as well - just tell us what you need.
We can make any type of plug-in or solder mounted interface module such as the ones illustrated here. Depicted are a circuit card stiffener with ground plane, two different plug-in modules for daughter card attachment, and a square riser for BGA surface mount hardware component on 0.8mm pitch spacing. Contact us with any requirement, no matter how intricate it may seem. 
Illustrated here are a couple of interface modules utilizing spring probe contacts to interface high performance test boards.  We can make nearly any configuration to handle your test requirement.  Contact us for more details.
This interface module was made to adapt a very high density 0.5mm pitch BGA leaded socket to a surface mount PCB configuration.  While functioning as an adaptor solution the design also served as a stack-up mechanism to raise the DUT component off the PCB while accommodating various test functions.
