PCB TEST FIXTURES
Whether you’re testing a single PCB sub assembly or a full panel of PCB modules, RTI’s PCB test fixtures are custom designed and manufactured to address your test challenges and work with your PCB layout.
DESIGNED FOR IN-CIRCUIT, FUNCTIONAL, & ENGINEERING TESTING
Our engineers begin with a GERBER or STEP file of your UUT and work with you to identify test points, keep out areas, and other aspects of your test configuration. Bed-of-Nails-style test fixtures provide precise alignment to the UUT to test points or connectors of choice, even in multi-board stack-ups where the UUT is only one of many components. Clean, streamlined, and robust designs can be made adaptable to accommodate a multitude of standard and custom printed circuit board footprints.
Design PCB Test Fixtures to Your Needs
Our robust and reliable designs come in a variety of sizes and footprints to suit your PCB scale and test application. Fixtures can accommodate standard PCB footprints such as Raspberry Pi and other single-board computers and fully custom PCBs. Most designs offer a bed of nails interface, but other interfaces are available. We specialize in designing and manufacturing custom test fixtures to meet unique test challenges.
Popular features of our large PCB test fixtures:
Custom contact methods:
We also offer PCB design for all signal routing and breakout boards incorporated into the test fixture to provide an out-of-the-box test solution. These boards route all signals between the pogo pins contacting the DUT and your outbound connector(s) of choice.
Frequent Questions About PCB Test Fixtures
There are multiple ways to do it. These are the common ways RTI uses:
- Precise alignment to test points using design features of the UUT such as non-plated through holes
- Internal board to board connections through cable interfaces, RTI’s connector savers, or high-speed mating connectors soldered to PCB
Can I add physical components like thermal, contamination, shock and vibrations, etc., to the process?
Yes. These are only a few examples:
- Heatsinks, heat spreaders, water blocks, air cooling, and other thermal management systems
- Passive and active vibration dampening measures for sensitive components
If I want to test a switch, does a robot actuate it? If I’m testing an LED is the operator or the machine the detector?
We can make pneumatic components within the fixture to engage. We’re also capable of including sensors for feedback and/or functionality.
- Pneumatics within the fixture can engage buttons, switches, or connectors on the UUT during test
- Inclusion of light, pressure, and temperature sensors for operator feedback and/or test functionality
There are multiple ways to create connections depending on your DUT and test requirements. These are a few:
- High speed and low inductance mating connectors for direct board-to-board interfacing
- Coaxial shielded contacts and wire-wrapped pins contact test points on the UUT
- Interposer PCBs in the fixture with controlled impedance and high-speed routing design practices
- Integration of high-speed coax and fiber connectors and custom cabling within the fixture.

Pogo Pin Blocks
Breakout test fixtures typically include a test socket and DUT board that route signals from your DUT to a connector or interface of choice. Transform your dedicated DUT board into a universal motherboard-daughterboard solution with pogo pin blocks that provide a board to board interface.
Robson Technologies, Inc. interconnects, fixtures and systems are carefully designed, manufactured, inspected, and individually tested prior to shipment. In the unlikely case you find a defect in materials or workmanship, we will promptly repair or replace the component.
