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.
Functional PCB Test Fixtures
Ideal for complex and Multi-Board test configurations in functional and in-circuit test applications. These fixtures utilize a 2 stage lid closing process involving a cam system to easily provide even vertical compression force across a high number of pins.
Benchtop Test Presses
Many of our PCB test fixtures utilize one of our universal Manual Presses or small scale sheet metal enclosures. This gives you a standardized design with a compact footprint to sit on your test bench beside your tester or measurement tool.
Mass Interconnect Test Fixtures
Connect to multiple PXI and VXI based instruments using ITA module based test fixtures. Compatible with a variety of Virgina Panel’s Mass Interconnect Panel receivers designed for rack mount fixtures.
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.
We 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. If you require that the test fixture include board(s) of your own design and fabrication, please contact us.
PCB Test Fixtures for Mass Interconnect Systems
Back panel featuring MIP Interface
PCB test fixtures interface with mass interconnect systems such as Virgina Panel’s “Mass Interconnect Panels” (MIPs) using sets of configurable ITA modules positioned on the front or back of the test fixture. This allows the fixture to interface with a variety of common PXI and VXI based instruments, each having their own unique configurations. Each mating connector I/O can be wired directly to its respective test probe for reliable signal integrity or interface with other components such as a device programmer or adapter board within the enclosure.
Each fixture can be customized internally for use across multiple applications throughout your test program. From characterization to validation to production test, each fixture is scalable to address various requirements at each stage. The low-profile bed-of-nails interface and two stage clamshell lid provide ample working distance while keeping 100% vertical compression force across the PCB. Swappable standoffs on the lid allow the fixture to test both bare boards and fully populated boards with strict keep out areas.
