Pneumatic Presses

RTI offers a broad range of standard footprint pneumatically operated Test Fixtures and has many years of experience in the design and manufacture of full custom manually operated test fixtures. These fixtures support a wide variety of requirements specifically tailored for those applications that call for pneumatic control of the test contact activation. These applications can also include the operation of switches located anywhere on the unit under test. Pneumatic fixtures provide full capabilities for test point contacting both topside and backside of the modules to be tested. These test points can be pads designed specifically for test access as well as connectors and some SMT’s including Coax. 

Pneumatic capabilities can also provide the unique capability of contacting connectors mounted laterally. This would include those located on the DUT edge as well as possible connectors mounted on an internal surface.

The signal paths from the test point contacts can be implemented via dedicated PCB or hand wired probes can be provided. There can be space under the fixture for electronics to support the test requirements with additional electrical access thru the Front or backside of the fixture.
 
Environmental control can also be provided with access/direct contact to bottom side mounted components or the complete operating area of the fixture can be enclosed for testing within a temperature chamber. RTI has both fluid and TEC temperature control products.

RTI can also provide RF shielding, either local to a specific area of the unit under test, or enclosing the complete fixture.

Note that for pneumatic operation, there may be ergonomic actuation control required for operator safety. RTI provides either electro-pneumatic switches or full pneumatic switch control. Pressure Regulators are also included.
