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.
