MANUAL TEST PRESS FIXTURES

Compact, portable, all-inclusive, and easy to use. Single lever operation and 100% vertical compression make manual test press fixtures an ideal solution for PCB, hybrid module, and high pin count device-level testing when complex test requirements cannot be met with a test socket and breakout board alone.

TEST PRESS FIXTURE DESIGN

Complete text press fixtures consist of a universal test press base and an interchangeable interface module. Our manually actuated test press bases range in size from 5.5 inches to 16+ inches wide to fit on your benchtop while containing all components required in your test setup. The final test press footprint may vary based on customer requirements, interface module size, and test press selection.

Design Manual Test Press Fixtures to Your Needs

Our manual test press fixtures are developed to be fully integrated test solutions that are ready for use as soon as they are received. You won’t face “Some assembly required” or “batteries not included” when working with RTI to develop a test press solution.

Test presses consist of a standalone base that is sized to your application and a removable interface module that manages all electrical interconnects incorporated into the working solution and aligns the unit under test (UUT) to the test points.

Common Test Press Bases

test press bases

Test press bases use robust stainless steel and ball-bearing linear guides for smooth vertical compression. This ensures consistent, repeatable, and reliable test results while preventing damage to the UUT or test probes during use.

Smaller 750 series test presses utilize a combination of clamshell and vertical guide designs while larger 752 series test presses are fully vertical.

Open Position

The lid sits at a 50˚ angle when the press is in the open state, giving the operator ample room to load and unload UUT(s) between test. The height of the interface module and length of standoffs on the lid impact this working area.

Resting Position

As the lever is pulled to close the lid, it first comes to rest in a horizontal position parallel to the baseplate. The standoffs installed on the lid sit above the UUT(s) without making contact and the UUT does not engage with the pogo pins.

Closed Position

As the lever is fully engaged, the lid travels 0.34” vertically on linear bearings to bring the fixture into a closed “test” position. This vertical travel applies even compression force across the UUT as the pogo pins are engaged.

Bed of Nails Interface Modules

Removable interface modules are the heart of the test fixture. They are responsible for fine alignment of UUT(s) at device loading, provide electrical contact to the bottom side of the UUTs during test, and include custom wiring or an adapter board to route signals to your test interface of choice.

A floating tray on the interface module holds and aligns the UUT(s) in a test-ready position above a bed-of-nails pogo pin array. Linear bearings with coiled springs on the interface module guide the floating plate and UUT(s) onto the pins as the fixture reaches test position. Floating trays on the interface module can also be swapped out if there are changes made to the UUT’s during the test process, eliminating the need to purchase entirely new modules for every iteration of a product design.
