PCB MODULE TEST SOCKETS
PCB module sockets are ideal for testing Flex, Rigid-Flex, PCB sub-assemblies, and multi-chip modules. Intelligent test socket and lid design ensure device compatibility without sacrificing performance or device level access.
PCB MODULE SOCKET DESIGN
Custom engineered with fine alignment features and intelligent design options that offer the most for device access and electrical performance. Our robust PCB module test sockets have a variety of customized layouts optimized for use across multiple test applications. Non-plated thru-holes on the UUT are used for fine alignment of the device to the pogo pins. Dowel pins in the socket base align with the non-plated thru-holes on the device and are essential for testing devices with small test pads, fine pitch, wide dimensional tolerances, or test points on the top and bottom of the device. Additional alignment techniques are available.
PCB Module Sockets
For Flex, Rigid-Flex, small PCB sub-assemblies, and multi-chip modules. Providing precise DUT alignment with relief cutouts for SMT components and more.
Socket Lids
Our lids can be designed to ensure device-level access, topside electrical contacts, and/or provide unobstructed support for special device features such as SMT components.
PCB Module Sockets Designed to Your Needs
Our capabilities range from RF modules to medical devices, camera modules to sensor modules, optical devices to sub-assemblies, Flex, Rigid-Flex assemblies and more.
We incorporate various design options from castellated contacts to compression mounting, multi-site to contacts on 2 levels, alignment features to fitting various sizes of your PCB module. Fully enclosed RF shielding can completely encompass the test socket for TX/RX signal integrity testing.
Custom lids can be designed to ensure device-level access, topside electrical contacts, and/or provide unobstructed support for special device features such as SMT components. Lids can also include high speed connectors to contact test points on the top of the UUT, clearances for antennas, heatsinks to contact tin lids or logical components
We are not limited in designing test solutions for custom devices. Please contact us to discuss your project or start your design.
Socket Alternative to Test Presses
PCB module test sockets are typically used for small PCBs. But sometimes these sockets are a better solution for larger boards instead of a test press fixture. Depending on the board’s components, test points, and alignment features, PCB module sockets may make more sense for your factory since they occupy less bench space and don’t require a test press resulting in a lower cost model. Please contact us to discuss your board and see if a socket is the right fit.

Castellated Contacts
- Pointed tip pogo pins can contact the rectangular landing pad around the castellation.
- If pads are not available around the castellation, pins with pin tip diameter larger than the cutout are used.
- Castellations on UUT can provide rough alignment of device to pogo pins.
- Submit STEP or GERBER files of your UUT PCB to an RTI engineer to review available options
Component Clearances
- Entire portions of the socket base can be cut away to provide access to the backside of the UUT
- Small pockets are milled out to offer clearance for surface mount components placed very close to test points.
- Relief cutouts can be incorporated into lids to avoid pressure sensitive areas on lidded devices or cut away completely for topside access
Probe Both Sides of Your Module
- Interposer type lids include pogo pins that contact test points located on the topside of your UUT
- A small PCB in the lid routes signals out to an array of contacts that mate with T-pins in the test socket body
- Non plated thru hole alignment is required for dual side contact sockets. Dowel pins in the lids provide keying and fine alignment to the socket body when closed
