Priority items to confirm · 4
01Traceable evidence availableUnconfirmed
Are these as-sliced SiC wafers, before grinding?
Record the ingot, slice order and material batch; use neighboring problems for backend die cutting.
Update engineering conditions →02Traceable evidence availableUnconfirmed
Are wire, tension, feed, rocking and fluid-delivery records traceable?
Use actual process settings and equipment limits; advertised precision is not a batch result.
Update engineering conditions →03Traceable evidence availableUnconfirmed
Are as-sliced thickness maps, cracks and damage measurements comparable?
Use matched references and sampling for thickness/TTV; an intact surface does not exclude subsurface damage.
Update engineering conditions →04Traceable evidence availableUnconfirmed
Are target thickness, downstream removal allowance and acceptance criteria defined?
Separate dimensional allowance from damage removal rather than optimizing thinning alone.

View source notes and limits
Takatori’s bilingual sheet dated March 18, 2026 identifies the SiC model, mechanisms and equipment specifications.
Scope and limitations Equipment specifications do not guarantee wafer thickness uniformity or damage depth; they do not establish package-dicing capability. What to prepare BLNKK suggests preparing ingot dimensions and material condition, target thickness, wire and slurry conditions, and acceptance methods for thickness variation and damage. Confirm with the supplier Confirm compatible workpieces, wire and feed settings, slurry controls and consumables. Arrange slicing trials followed by thickness, warpage and damage measurements.
