Priority items to confirm · 4
01Per-ball heights / datums are traceableUnconfirmed
Are per-ball heights after ball attachment and before placement available with a clearly defined reference plane?
Record ball-apex sampling, ball coordinates, missing balls, and measurement support. Overall package bow cannot substitute for per-ball coplanarity.
Update engineering conditions →02Package / board / support geometry can be correlatedUnconfirmed
Is geometry at matching locations comparable across the package, board surface / pads, and placement support?
Height datums must be correlated with the actual initial contact surface. The free-state top surface cannot directly establish ball-to-board gaps.
Update engineering conditions →03Paste deposition / placement / contact are comparableUnconfirmed
Are printing / pads, placement alignment, compression, and initial-contact records traceable?
Coplanarity and paste deposition / placement jointly affect contact. Establish records first; do not specify universal pressure or paste height.
Update engineering conditions →04Pre-board-reflow heights / contact are recordedUnconfirmed
Were observations made after ball attachment / at initial placement, before board-level reflow?
Retain HiP separately for lack of fusion after board-level reflow. TCB microbump heights are a neighboring topic; do not apply this ball-array process to them.

View source notes and limits
The page documents design-to-production workflows and thermal, electromagnetic and warpage analysis examples.
Scope and limitations Substrate capabilities do not establish final ball coplanarity; development-stage patterns are not universal supply specifications. What to prepare BLNKK suggests preparing stackups, pad/ball layouts, ball-attachment processes, thermal histories and height/warpage measurements. Confirm with the supplier Confirm materials, design rules, simulation assumptions/correlation and separate substrate/assembly acceptance criteria.
- Nordson Test & Inspection · SQ3000S visible-contact and package coplanarity ↗
View source notes and limits
The official page and two-page sheet describe AOI/SPI/CMM, sensor choices and height/coplanarity functions.
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.
- KLA · ICOS T3 / T7 BGA-ball coplanarity inspection ↗
View source notes and limits
The current page confirms T3/T7 and 3D metrology; the brochure explicitly lists BGA/CSP ball coplanarity, position, offset and pitch.
Scope and limitations Per-ball measurements require optical access and suitable modules; buried assembled balls are outside this direct method. Coplanarity alone does not diagnose opens; confirm current availability of brochure configurations. What to prepare BLNKK suggests preparing ball geometry, surface condition, coplanarity tolerance, datum and handling needs, plus repeatability/reproducibility validation. Confirm with the supplier Confirm available modules and datum definitions; validate sample-specific detection, measurement error and data output.
- MA-tek · MA-tek laser ball-placement specimen service ↗
View source notes and limits
MA-tek documents the method and named PacTech SB²-M system.

Confirm with the supplier Confirm accepted geometry/materials, laser and rework conditions, process records and joint-quality verification.
- Micross Components · Micross finished-BGA reballing and alloy conversion ↗
View source notes and limits
Micross lists the process and pitches from 0.40 mm; it supplies no post-rework coplanarity or fatigue result for your device on this page.
Scope and limitations Reballing changes alloy and thermal history; improved coplanarity or fatigue life is not automatic. Published pitch does not qualify every device or establish microbump capability. What to prepare BLNKK suggests preparing part/ball-layout details, existing and target alloys, diameters and reflow/rework history. Height and electrical baselines can support before/after comparisons. Confirm with the supplier Confirm compatibility, removal/refinishing/attachment thermal steps and pad controls. Agree on post-rework height, coplanarity, electrical and relevant reliability checks and acceptance criteria.

Confirm with the supplier Confirm the model, optics, reflective-surface treatment, actual sample temperature, measurement uncertainty and support effects.
- ITW EAE · Centurion reflow for package ball mounting ↗
View source notes and limits
Current whole-oven and semiconductor pages list package ball reflow.
Scope and limitations Control records are not every ball’s temperature. Solder amount, pads, support and warpage also affect coplanarity. What to prepare BLNKK suggests initial ball-height maps, carrier/support drawings, solder conditions and measured profiles, retaining same-location comparisons. Confirm with the supplier Confirm heating/cooling, atmosphere, transport/support, traceability data and product-specific profile validation.
- Polytec · TopMap Micro.View CSI 3D metrology for microstructures and BGA ↗

What to do next
No result provided. Clarify key conditions before arranging an assessment.
- Are per-ball heights after ball attachment and before placement available with a clearly defined reference plane?
What to prepare
- Per-ball coordinates and datums; Normal / abnormal samples before placement; Ball diameters / package dimensions and support
- Per-ball height datums and coordinates; Visible ball surfaces / support; Package geometry at matching locations
- Per-ball and two-sided correlation maps; Printing / placement and initial-contact traces; Normal / abnormal controls with support held constant
- Consider FC-BGA processor substrates; distinguish substrate scope from subsequent ball attachment and assembly.
- For visible surfaces. The sheet lists BGA components and package coplanarity; individual ball measurements still require accessible ball ends and suitable fixturing.
- Published for outgoing BGA, CSP and WLP inspection, with tray output on T3 and tape output on T7. Select modules for the sample.
- Consider R&D, small-batch or BGA-rework specimens. The page lists 100–350 μm balls; project acceptance requires confirmation.
- Confirm the specific ceramic or plastic BGA, pitch, diameter, alloy and package condition with the provider.
- Consider it for optically accessible WLCSP contacts, with device surfaces and handling assessed on samples.
- Published applications include BGA, CSP and flip-chip. Match grade to pads, target diameter and the intended reflow process.
- Compare thermal warpage and topography with model-specific validation of ball pitch, reflective surfaces, support and measurement area.
- The supplier specifically lists ball-mount reflow. Confirm carriers, ball/pad conditions and transport for the selected configuration.
- Potential evaluations include BGA balls, bumps and microstructured surfaces for height, coplanarity and topography. Optics, sample stages and stitching coverage require sample-specific selection; surface profiling does not establish in-reflow dynamic warpage measurement. Ball pitch/diameter and package outline Seating datum and package-bow subtraction Objective/reflectivity and repeated scans
- The named page lists lead frames, BGAs, CSPs and small precision parts. Portfolio fan-out applications require sample-specific confirmation. Confirm Z option/calibration; provide ball pitch/finish/occlusion, plane, support and MSA samples.
Questions to discuss
- Which reference plane is used for per-ball heights, and how are missing balls / obscuration handled?
- Is package / board geometry and support comparable at matching locations?
