Every project begins with a comprehensive engineering review of your ATE load board or DUT interface design files. We evaluate:
Controlled impedance requirements
High-speed signal routing
Material selection (FR4, Rogers, specialty laminates)
Via structures (blind, buried, microvias)
Mechanical tolerances, handler and prober and interface Aaignment
Early-stage validation reduces risk, shortens development cycles, and prevents costly redesigns before fabrication begins.
High-performance ATE environments demand precision stackup design. We engineer layer structures that support:
4–44+ layer PCB builds
Controlled impedance routing
High-speed and RF applications
Power integrity and signal isolation
Advanced via structures
Our stackup planning ensures electrical performance aligns with fabrication capability — critical for semiconductor test applications.
Design for Manufacturability (DFM) is integrated into every project. We work closely with qualified PCB fabrication and PCB assembly partners to align design intent with production realities.
This includes:
Drill tolerances and aspect ratios
Material availability and lead times
Panelization strategy
Yield optimization
Assembly process validation
This collaborative approach ensures repeatable, production-ready ATE load boards and DUT interface boards.
Finley Design provides active oversight during ATE PCB fabrication and assembly to maintain precision and consistency.
We coordinate:
Fabrication checkpoints
Controlled impedance verification
Material certification review
Process documentation validation
Our engineering-focused approach ensures every board meets performance and reliability expectations for demanding test environments.
Completed boards undergo detailed inspection prior to release. We verify:
Fine-pitch BGA and QFN placement
Connector alignment and mechanical interface accuracy
Structural components and stiffeners
Functional integration readiness
Every ATE load board and DUT interface assembly is reviewed to confirm it is ready for handler, tester, or prober integration.
