Test Fixtures & Programs

CheckSum’s Turnkey Test Fixture and Program Services

CheckSum is the only automatic test equipment (ATE) supplier that offers complete turnkey packages that are ready for production when the land on your receiving dock. This means you receive optimum performance and reliability at the lowest overall cost.

Not only is the price of Analyst systems a fraction of traditional ICT, more importantly, ongoing operating costs (fixtures, programs, and support) are typically 50% less.

Our focus on minimizing fixture cost and simplifying programming saves money each time a new test job comes on line. Electronic manufacturers who switchover to CheckSum systems find the cost savings to be immediate and dramatic.

In Circuit Test Fixtures and Fixture Kits

CheckSum pneumatic and mechanical test fixtures are rugged, reliable and inexpensive-especially when compared to the heavy vacuum fixtures required by traditional in circuit testers.

CheckSum fixturing is compatible with all of CheckSum’s test systems. Since the electronics are isolated from the fixture you can use CheckSum’s factory-built fixtures or build your own special fixturing or adapters that can accommodate ribbon-cable connectors.

CheckSum Fixture Systems and Fixture Kits

Model 12KN Dual Level Long-Travel Pneumatic Fixture System

The 12KN Dual Level Pneumatic Fixture System is integrated into a rack-cabinet and designed to be the basis for CheckSum bed-of-nails test systems.  The long-travel press eliminates the need to open and close a lid between tests. The fixture kits are easily changed by sliding the fixture top plate and base into place. The system uses a universal spring-probe fixture interface. The fixture system can accommodate up to 5200 test points and uses standard CheckSum fixture kits.  Integrated into the system is rack space for system electronics and an operator keypad with a minimum selection of buttons to make it easy, safe, and error-free for the operator to use.   The 12KN is compatible with existing CheckSum KIT1000-QC and KIT2KN-QC fixtures.  A safety light curtain provides operator safety.

Fixture Guidelines: Assembly size can be up to (approximately) 24 x 13.2 inches (61 x 33.5 cm), dual level, single-sided and double-sided probing plus TestJet.

Model TR-7-1000-QC Pneumatic Fixture System

The TR-7-1000-QC is a new version of our popular TR-7-1000 pneumatic fixture receiver. Uses air pressure to press the assembly being tested onto spring probes. Usable to 1000 test system connections, the Model TR-7-1000-QC is ideal for most testing applications including dual-level fixturing. Using low-cost removable fixture kits, it can accommodate assemblies where adding a vacuum seal is difficult.

Fixture Guidelines: Assembly size can be up to (approximately) 16 x 13.2 inches (40.6 x 33.5 cm), dual or single-sided probing and TestJet.

Model TR-5-400-QC Mechanical-Advantage Fixture System

Designed for test fixturing of assemblies with up to 400 test points. The Fixture System consists of a reusable Fixture Press that is used in conjunction with low-cost, easily interchanged Fixture Kits.

Fixture Guidelines: Assembly size can be up to (approximately) 11.75 x 8.5 inches (30 x 21.5 cm), dual or single-sided probing and TestJet.

Model TR-5 Mechanical Bed-of-Nails Fixture Kits

Uses mechanical pressure from the operator to press the assembly being tested onto spring probes. Usable to about 150 test system connections, the Model TR-5 is well suited for applications where vacuum is not available, to minimize cost, or for assemblies where vacuum sealing is difficult.

Fixture Guidelines: Assembly size can be up to (approximately) 14 x 14 inches (35.5 x 35.5 cm), bottom-side probes only.

TR-3-Console Vacuum Bed-of-Nails Fixture System

Console setup for system test electronics to accept industry-standard GR-2270 style test heads with up to 1500 test system connections.  Automatic vacuum control and vacuum gauge. Connects to your vacuum source.

Fixture Guidelines: Assembly size can be up to (approximately) 21 x 17 inches (53.3 x 43 cm), single-sided probing and dual or single-sided TestJet.

 

TR-3A Bench-Top Vacuum Bed-of-Nails Fixture System

Bench-top setup to connect system test electronics to industry-standard GR-2270 style test heads with up to 1500 test system connections.  Automatic vacuum control. Connects to your vacuum source.

Fixture Guidelines: Assembly size can be up to (approximately) 21 x 17 inches (53.3 x 43 cm), single-sided probing and dual or single-sided TestJet.

Test Executive Software

The software shipped with every Analyst system includes the Test Executive that runs under Windows OS. The test executive features three primary functions:

 

  • Test program creation and validation. Interactive measurement analysis and built-in CAD conversion tools allow complete test generation in a few hours. Panelization Wizard makes test program generation easy for assemblies with multiple boards attached to a single panel.
  • Test program execution, including MultiWriter ISP programming. It handles single or panelized boards with equal adeptness.
  • Test results tracking to identify problem components and trend analysis that includes real-time Pareto graphics to track production yields and identifies problem components. Graphical X-Bar/Sigma Report identifies process or component variation trends.

Other test executive capabilities include login and password protection to restrict access to specific features of the test station.
