iST custom high-speed test-fixture service

Integrated Service Technology (iST) · Engineering measurement and characterization

Purpose: Controlled ports, terminations and connections are needed to compare high-speed coupling without confusing fixture effects with specimen differences.
Technical approach: iST offers custom fixture planning, design, verification and production to implement a physical measurement interface.
Scope of use: For accessible test ports and defined interface requirements; fine-pitch interposer access requires individual feasibility review.
Limitations and open questions: These evaluation considerations are compiled by BLNKK from public information. They are not supplier guarantees or a mandatory submission checklist.
Scope and limitations
Board-level fixtures do not automatically fit interposers. Fixture loss and coupling need calibration or de-embedding; delivery alone is not completed crosstalk validation.
What to prepare
BLNKK suggests preparing port layouts, pitch, connections, terminations, target bandwidth, specimen constraints and intended instruments/calibration.
Confirm with the supplier
Confirm supported interfaces, mechanical/electrical design, verification and de-embedding methods, deliverables, acceptance criteria and production arrangements.
Public evidence: The service page describes customization and PCIe/Ethernet examples, rather than a universal interposer fixture specification.
