SQ3000S visible-contact and package coplanarity

Nordson Test & Inspection · Engineering metrology and failure analysis

Purpose: Comparing visible terminal height and package coplanarity requires a consistent reference plane and repeatable optical measurements.
Technical approach: SQ3000S uses 3D optical sensing and MRS multi-reflection suppression with CMM functions for height, coplanarity and distance.
Scope of use: For visible surfaces. The sheet lists BGA components and package coplanarity; individual ball measurements still require accessible ball ends and suitable fixturing.
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
Buried balls after assembly cannot be measured directly by this optical method. Sensor choice and reflections matter; certification-target accuracy is not package accuracy.
What to prepare
BLNKK suggests defining measured/reference surfaces, visible terminals, tolerances, fixtures and surface condition, with calibration and repeatability data.
Confirm with the supplier
Confirm sensor, range and per-ball visibility, then validate height, coplanarity and measurement-system variation on representative samples.
Public evidence: The official page and two-page sheet describe AOI/SPI/CMM, sensor choices and height/coplanarity functions.
