RJI Technical Sales, since our inception, has been engaged in the sales of sockets and test contactors.
Applications include test, burn-in and failure analysis. We have years of experience in the use of many
contact technologies and are well versed in all of the latest socket designs.






We're proud of our contacts!
We specialize in the design and manufacture
of IC Contacts that offer outstanding
performance and value. And we pride
ourselves in our contacts with customers that
grow into long term partnerships.
Contacts you can trust!
With over two decades of growth, our proven
track record continues to earn the respect
from such major handler manufacturers as
Rasco, Multitest, SRM, Aseco, Aetrium, MCT,
Xufeng, Exatron, Yoshigawa, Pentamaster,
Tesec, Synax and Seiko Epson. Chip
manufacturers, OEM's, and test facilities, in
addition to handler manufacturers worldwide,
know and trust our products and our
guarantee of satisfaction.
A commitment to total process control
continues to be our road to success. Two
12,000 square-foot facilities house
engineering, metal prep, production and
assembly, machine shop, quality control and
support services. And in each department we
build-in performance and quality from the
ground up –– from initial design to finished
product.

CSI is a leading manufacturer of high performance test sockets used
in many different areas of semiconductor testing. CSI uses quality
principals in all stages of design and manufacturing, which in tandem
with our dedication to customer service, allows us to deliver superior
quality products and services.
CSI brings over 15 years of experience, in socket design to our
customers. We have at our disposal a vast data base of existing
socket designs. Our manufacturing facility is equipped with multiple
state of the art CNC machine tools, which are individually connected
to a CAD/CAM engineering work stations. This set up gives our
manufacturing engineers extreme flexibility to create new deigns, and
execute old programs with high quality, maximizing productivity and
efficiency.
CSI uses spring probe contacts as the basis for it's socket design.
Spring probe contacts combine long life with superior electrical, and
mechanical performance, which makes them the ideal contacting
medium for all facets of Semiconductor testing. We use five standard
spring probes that allow us to cover all pitches from 0.4mm to
1.27mm and beyond. Our standard spring probes are rated for 500K
insertions, and -1db bandwidth of 5Ghz, with contact resistance of
less than 100mOHM. We also have higher performance contacts that
we use routinely for applications that require this extra performance.
Contech Solutions also supplies a full range of receptacles (or,
socket savers as some call them) for all of the popular burn-in
sockets on the market today. They can mate sockets from
Yamaichi, Enplas, Loranger, Plastronics, Azimuth, and many others.
