Comprehensive Fixture Design, Without Compromise
Optimized Signal Routing
Our PCB test fixtures feature an internal routing board to carry signals from your DUT to any connector or interface of choice, positioned on the fixture where you need them most.
User-Friendly Operation
With options like manual lever or pneumatic piston actuation, our fixtures are designed for ease of use, delivering consistent and repeatable results with minimal operator effort.
Precision and Reliability
Featuring bed-of-nails-style modular pin blocks and keyed alignment features, our designs offer precise positioning and true vertical compression while contacting test points on the top and bottom of the unit under test.
Integrated Functionality
Incorporate advanced features like built-in single-board computers, device programmers, RF shielding, and custom contact methods to create a comprehensive, stand-alone testing solution.

Out-of-the-Box; Onto the Bench PCB Test Fixture Solutions
Our fully integrated PCB test fixtures are shipped to you in a "ready-to-test" condition. Simply remove them from the shipping container, put them on the bench, connect your tester and equipment, calibrate and start testing straight away.
Specialized Contact Methods and Shielding
We offer a range of customizable and modular bed-of-nails contact methods to probe test points across the entire UUT including the top, bottom and sides. Mating connector panels with high-speed connectors or shielded coaxial cables can be built into the test bed with regulated lateral motion to engage the UUT from the side.
Our fixtures also feature RF shielding techniques to protect against internal or external EMI/RF interference. Conductive alodine-plated panels, gasketing, and mesh fan screens with Faraday cage principles ensure your test environment stays controlled to your specification.
Precision Engineering for Comprehensive Testing
Our engineering team collaborates with you from the outset, using your GERBER or STEP file to identify critical test points, keep-out areas, and other essential aspects of your DUT and test configuration. Sample UUT boards are required for multi-point quality assurance prior to shipping.
Our bed-of-nails style test beds complete with floating trays and guide-pins ensure precise alignment with your Unit Under Test (UUT), providing reliable contact with test points and/or connectors on your device, even in complex multi-board stack-ups.
Versatile Solutions for In-Circuit and Functional Test
Our PCB test fixtures are ideal for intricate and multi-board test setups. These functional test fixtures feature a two-stage lid closing process with a cam system that ensures true-vertical compression across the surface of your unit under test.
The inclusion of secondary and tertiary driver boards along with any other hardware dependencies built directly into the fixture makes RTI's PCB test fixtures perfect for stand-alone in-circuit and functional test processes.

Getting Started with RTI
A working solution starts with a working understanding
The following customer supplied information is required to ensure RTI meets an on-time schedule and provides an error-free test fixture solution. Incomplete data packages required at the time of design will cause project delays and significant changes to scope of work may result in an order that cannot be completed. RTI can provide a mutual NDA or fill out your company's mutual NDA if necessary, before exchanging any sensitive information.
Information required at time of quote:
An RTI Applications engineer will review each Statement of Work (SOW) and define any additional special features before submitting a quotation. The quote provides a detailed description of design and test requirements and includes essential information needed to satisfy these requirements.
- Minimum center to center spacing, pad size, and number of test points
- Alignment features available on the DUT
- Special test probes required
- Internal routing or wiring
- Intended interface with tester
- Type of fixture base platform and modifications
- Inclusion of sub-assemblies and other components
- Environmental and operational emulation requirements
The RTI Applications Engineer will request additional details about this essential information if not covered in your original SOW.
Information required at time of design:
RTI's mechanical and/or PCB design engineers will require technical drawings, sample(s) of the Unit(s) Under Test, and access to any other customer provided components that need to be included in the final product.
Files should include the top layer and/or silkscreen layer to identify installed components and relative positioning. Files should be combined and compressed in .zip format when possible and emailed to sale@electricaer.com. Contact RTI if the files are too large to send via email.
Accepted File Types:
- GERBER files that include top/bottom silkscreen and any layers of interest
- 3D STEP format
- CAD in .dwg or .dxf format
Additional Information and Samples:
- A sample device (assembled) might be needed at time of design.
- A sample device (non-functioning okay) will be needed at time of production for multi-point quality assurance prior to shipping.
