Test Fixtures
Custom fixtures for reliable and repeatable electronics testing. Designed around your product, test strategy and production environment — from development and verification to volume production.
- Built for
- Your product, PCB assembly or product family
- Test types
- In-circuit, PCBA, functional and final test
- Configuration
- Manual, semi-automated or automated
- Interface
- Custom probing, connectors and product interfaces
- Integration
- Virinco Test Platforms or existing test systems

Custom-built for your product
Every product presents different test requirements. We engineer each fixture around the DUT, required test coverage, production volume and operator workflow.
Your product
We start with the DUT, interfaces, test points, mechanical constraints and expected production volumes.
Fixture engineering
Mechanical design, probing, connectors, electronics and operator handling are engineered as one solution.
Production-ready fixture
The completed fixture is integrated, verified and documented for reliable day-to-day production testing.
Key features
Designed around the DUT
Mechanical interfaces, probing and connections are engineered specifically for the product being tested.
Reliable contact
Robust mechanics and controlled probing provide repeatable electrical contact over repeated test cycles.
Exchangeable cassettes
Where appropriate, interchangeable cassettes allow one fixture concept to support product variants and future revisions.
Easy to maintain
Serviceable mechanics, accessible interfaces and replaceable wear parts simplify maintenance in production.
Built for production
Operator handling, cycle time, ergonomics and production volumes are considered as part of the design.
Platform independent
Fixtures can be integrated with Virinco Test Platforms or engineered for an existing customer test system.
The interface between product and test system
A production test fixture forms the physical and electrical interface between your product and the test system. Good fixture design combines mechanics, probing, connectors, electronics and operator handling into one reliable interface.
Because we also develop test systems and test software, we design the fixture as part of the complete test architecture — not as an isolated mechanical component.

Send us your product data, test requirements and expected production volumes. We engineer the fixture, verify it against the product and deliver a documented solution ready for integration into your test environment.
Questions we get asked
What information do you need to design a fixture?
Product drawings, PCB data, test points, interfaces, test requirements and expected production volumes give us the starting point. We can also help define the test strategy where it is not yet established.
Can a fixture support several product variants?
Yes. Where the products share suitable interfaces, exchangeable cassettes or adaptable mechanics can allow one fixture concept to support several variants.
Can you build a fixture for our existing test system?
Yes. A Virinco Test Platform is not required. We can design the mechanical and electrical interface around an existing customer test system.
When should fixture development start?
Preferably before the product design is frozen. Early involvement allows test access, mechanics and production requirements to be considered while changes are still relatively inexpensive.
Can Virinco deliver the complete test system?
Yes. A fixture can be delivered as part of a complete production test solution including instrumentation, test software, system integration and documentation.
What happens when our product changes?
We design for maintainability and future revisions where practical. Depending on the change, this may mean replacing a cassette or interface rather than rebuilding the complete fixture.
