CUSTOM SOCKET DESIGN
Push the limits of what you can expect with a custom socket design. Our custom test sockets and lids are designed and built from the ground up to accomplish what off-the-shelf sockets can’t.
CUSTOM DESIGN OPTIONS
Custom sockets offer the most flexibility to design, material, interface types, and accessibility to your DUT/UUT. The example below shows a variety of design options that can be applied to most socket orders. Discuss what design options are available for your next project with an RTI engineer today.
Topside Relief Cutouts
Machined pockets in the test socket provide clearance for SMD components installed on the bottom side of the DUT.
Backside Relief Cutouts
Machined cutouts on the PCB side of the socket body provide clearance for SMD components installed as close as 0.02 inch on the DUT board.
Temperature Monitoring
A built-in Resistance Temperature Detector (RTD) contacts the DUT and provides precise temperature monitoring down to 0.1°C.
Replaceable Inserts
High volume test can wear out the pocket that aligns the DUT to the pins. Replaceable inserts reduce cost, downtime, and extend socket life.
Kelvin Contacts
Test sense and force of each lead on the DUT using a pair of traditional fine pitch pogo pins or specialized Kelvin pins based on lead type.
Interstitial & Very Fine Pitch
Drilled and pinned for packages with multiple pitches and/or irregular load patterns. Very fine pitch (<0.3mm) for high-density packages.
RF & High Speed
Elastomeric & SILMAT™
High-Temp Ceramic
High Pin Counts
Zero Insertion Force (ZIF)
Mechanically improved alternative to injection molded plastic ZIF sockets. Mates with a receptacle or soldered directly to the DUT board.
Space Saving Burn-In
Populate your burn-in boards with more sockets than ever using compact clamshell sockets as small as 0.9in.
Heatsinks
Floating or fixed height nickel-plated copper (NiCu) slugs make direct contact to DUT through a hole in the socket body and PCB.
Backside Access
Holes machined into the socket base and PCB provides physical and optical backside access to the DUT during probing, inspection, and test.
Multiple Test Sites
Economic sockets ideal for mid-volume hand test. Test multiple devices of the same or different footprints using the same test socket body.
Standard Sizes Selection
Our conventional 0.9in socket footprints save space on the DUT board and are compatible with a variety of lid styles.
CMOS Image Sensor
Complete visibility of sensor area via topside or backside access, even when devices have test points on the same side as the sensor.
CSP & Bare Die
100% edge-to-edge visibility of bare die chip scale packages using a quartz or sapphire glass swatch to apply compression force.
Custom Socket Designs Built to Your Needs
We build custom socket designs for complex UUTs (units under test) and custom DUTs (device under test). Our custom sockets are ideal for applications where socket design and test requirements are not met by standard off-the-shelf solutions. This includes, but is not limited to burn-in, failure analysis, high current, high performance, temperature testing, RF characterization, and more.
We build high-performance and reliable sockets designed to your DUT or UUT and test applications. We have various design options from custom footprints to low-profile, contacts on any side of your device to interfaces with auto-handlers, open socket bases to open lids, and more.
