How VR Industries Approaches Functional Testing
Our team works directly with customers to understand their product’s functional requirements and establish appropriate test parameters. Functional test programs and fixtures are developed to exercise each assembly through its operating range, generating documented results that support traceability and compliance requirements.
For programs requiring it, functional testing is followed by burn-in services, where assemblies are operated under elevated conditions for a defined period to identify early-life failures before the product reaches the end customer. Together, functional test and burn-in form a comprehensive final validation stage within our multi-step quality process.
Our functional testing services are supported by:
- Customer-collaborated test program development aligned to product specifications
- Documented test results and traceability records meeting ISO 9001 and ISO 13485 requirements
- Burn-in services for programs requiring accelerated life screening
- Integration with upstream AOI and in-circuit testing for complete defect coverage
Functional Testing as Part of a Layered Quality System
Functional testing does not operate in isolation at VR Industries. It is the final stage in a structured inspection and test flow that begins at incoming material verification and continues through automated optical inspection (AOI), in-circuit testing, functional test, and burn-in where applicable. This layered approach is designed to intercept defects at the earliest – and least costly – stage of production, with functional test serving as the definitive confirmation of product integrity.
Our quality system is certified to ISO 9001 and ISO 13485 standards, and our manufacturing processes adhere to IPC-A-610 and J-STD-001 requirements. For defense programs, our ITAR-registered environment ensures appropriate controls are maintained throughout the functional test process, including secure handling of test data and assembly documentation.
Supporting quality elements that complement functional test include:
- Automated optical inspection at post-paste, post-placement, and post-reflow stages
- High-resolution x-ray inspection for BGA verification and hidden joint analysis
- Complete component traceability from incoming inspection through final test
Validating Performance Before Every Delivery
At VR Industries, functional testing reflects our broader commitment to delivering assemblies that meet your requirements – not assemblies that simply pass a manufacturing inspection. By treating functional test as a customer-specific validation step rather than a generic process, we ensure that test coverage aligns with how your product will actually be used.
