The top Automated Test Equipment manufacturers count on Circuit Check. We fabricate and customize in-circuit fixtures for testers made by Agilent Technologies, GenRad, Teradyne and others.
 

Customers know they can come to us for the latest technology and the utmost precision. For example, our engineers developed Fixture Design Assistant, a proprietary program suite that translates electronic files into automated instructions for fixture fabrication. Each fixture is carefully designed for contacting test targets. We routinely use spring probes to contact BGAs, Micro BGAs and micro vias as small as 0.012, and test pads as small as 0.018 on both the top and bottom of circuit boards.

When spring-loaded probes aren't practical, we use Thru-Connector tests to contact connectors on any surface or edge of a circuit board. These tests can be implemented by a number of methods: spring probes, mating connectors, sacrificial SMT connectors, and stabber cards. We have used stabber cards for SCSI, PCI, PCMCIA, AGP, DIMM, and Slot 1 and 2 connectors.

We offer a variety of options for obtaining desired test coverage

• Vacuum covers
• Heavy-duty gates
• Button and switch actuation
• Pneumatic and manual drive side-contacting units
  
• Pneumatic drive fixtures
• Manual drive fixtures

When high speed signal measurements and large node count boards are required, Wireless Test Fixtures are the answer. A printed circuit board with double-ended receptacles eliminates the wire bulk and improves test performance.

Our engineering department designs the wireless board in-house for Agilent Technologies and GenRad interfaces.Our Automated Verification System checks wiring in all in-circuit test fixture for correct probe locations wired to the interface, shorts to other locations and shorts between power and ground planes.
