Why functional testing matters
A PCBA can pass visual inspection but still fail in real operating conditions. Functional testing verifies power-up behavior, signal response, firmware operation, interface performance and customer-defined acceptance criteria.
ICT, programming and FCT roles
ICT focuses on electrical connectivity and component-level verification through fixtures. Programming loads firmware or configuration data. Functional testing validates the assembly under operating logic closer to the final product environment.
Test fixture and failure feedback
A good test strategy is built with fixture design, test coverage, pass / fail criteria and failure feedback. When a board fails, test data should help engineering teams identify whether the issue is assembly-related, component-related, firmware-related or design-related.
YourPCB validation support
YourPCB supports programming, ICT support, functional test coordination and inspection-driven failure analysis to help customers move from prototype verification to stable delivery.
RFQ preparation checklist
A clear RFQ package allows the engineering team to identify manufacturability risk earlier and respond with more accurate technical feedback. Before sending a request, prepare production data, target quantity, delivery expectations and quality requirements as completely as possible.
- Gerber / ODB++ data and fabrication drawing
- BOM, Pick & Place and assembly drawing when SMT is required
- Stack-up, impedance targets and material requirements
- Inspection, programming, ICT / FCT and packaging requirements
Why customers work with YourPCB
YourPCB combines engineering review, controlled PCB fabrication, SMT assembly, inspection, testing and responsive communication. The goal is not only to deliver boards, but to help customers reduce technical uncertainty before production and improve long-term manufacturing reliability.
