O-INSPECT heat-spreader datum and geometry review

ZEISS Industrial Quality Solutions · Engineering measurement and characterization

Purpose: Check accessible heat-spreader or support-part dimensions, datums and form before assessing TIM contact.
Technical approach: Optical imaging combines with tactile coordinate measurement; optional DotScan enables non-contact topography.
Scope of use: Select machine size and sensors for accessible features, surface conditions and the agreed support/datum scheme.
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
Component dimensions alone do not establish assembled TIM gaps or resistance. Fixturing and probe loads can affect thin parts; optional sensors do not share one universal resolution/error specification.
What to prepare
BLNKK suggests preparing drawings, datums, tolerances, surfaces, fixture details and intended contact regions. Assembly preload or existing shape data can help relate the measurement to actual use.
Confirm with the supplier
Confirm feature access, sensor/probe conditions and controls for fixture deformation and measurement error. Agree on separate assembled-gap or thermal comparisons if contact performance is the intended conclusion.
Public evidence: ZEISS publishes O-INSPECT multisensor and configuration data, not a validated assembled-TIM contact or thermal-resistance result.
