The
TestFixture provides the interface between the Automatiq TestSystem
and the Unit Under Test (UUT). Since it is removable,
additional TestFixtures can be provided for each board or circuit to
be tested.
The TestFixture provides a place to mount the UUT (either with connectors or in a Bed-of-Nails fixture) and contains the wiring between the Automatiq TestSystem and the UUT. In addition it can house circuits to interface between the TestSystem and the UUT.
The TestFixture makes contact with the individual TestModules in the TestStation using standard pogo pins. They provide reliable gold-to-gold connections that are rated for over 100,000 insertions of the TestFixture. Up to 1200 contacts can be made with the TestStation. The TestStation provides a built-in vacuum pull-down system to load the TestFixture.
The
signals from the TestStation are brought out on 60 pin dual row
headers (0.025” square pins on 0.100” centers). Connections can be
made with wire wrap, ribbon cable with IDC connectors, or loose
wires with modular connectors.
In most cases, multicolor ribbon cables with IDC connectors provide the most versatile option. The ribbon cable can be ripped apart and wired directly to the UUT connections.
Adapter
boards provide a place for interface circuits between the UUT and
the Automatiq Test System. These circuits can be as simple as an
instrument amplifier to amplify a milivolt signal or as complicated
as a microprocessor to generate complex interface signals. The
TestFixture has positions for up to 5 Adapter Boards. Blank Adapter
Boards with an array of component mounting pads are available as
well as boards with specific circuits.
Connections to the Automatiq Test System can be made using cables to the UUT connectors or via a bed-of-nails fixture. See the TestFixtures section of the Automatiq Test System Design Guide for additional information. The best solution depends on the application.

The
ready-to-wire Standard TestFixture Kit is ideal for low volume
products that don't justify bed-of-nails test fixtures. By
utilizing connectors that plug into the UUT, a TestFixture can be
constructed quickly and inexpensively.
The Standard TestFixture Kit provides a TestFixture housing, an Interconnect PC board, two Adapter Boards, and three wiring cables along with the appropriate hardware.
The Standard TestFixture is about 16.5" x 7.5" and provides a mounting area of about 15" x 7.5". It can accommodate about 1.75" inside the enclosure.

The
Bed-of-Nails TestFixture Kit is ideal for medium to high volume
products where speed of loading and long life can justify the extra
expense and complexity of the fixture.
The basic Clamshell fixture does not include the TestFixture base. TestFixture Kits are available with a cutout and mounting hardware to accommodate either Clamshell fixture.
The Standard Clamshell fixture is 8.2" x 10" suitable for a 6" x 9" board. The Wide Clamshell fixture is 8.3" x 14" and is suitable for a 6" x 13" board. Contact Automatiq directly for custom sizes.
The Clamshell fixture is provided undrilled. A complete fixture including drilling, installed pogo pins, and board location hardware is available. Pin and mounting positions may be provided by the customer or can be determined by Automatiq using Gerbers, schematics, and test-point lists. Contact Automatiq directly for a quote for a complete Bed-of-Nails TestFixture either wired, or ready to wire.
The Clamshell Bed-of-Nails fixture described above is designed to be used with the Automatiq TestSystem. Click here to see the Clamshell Bed-of-Nails fixture with free-standing bases for custom test fixtures.
