Asahi Kasei SUNFORT TA fine-pattern dry film resist
Asahi Kasei · Material properties and interface engineering
- Purpose
- Compare fine-pattern resist processing for package substrates and interposers where circuit separation matters.
- Technical approach
- Dry film supports double-sided lamination and patterning with stepper or LDI exposure.
- Scope of use
- Consider compatible substrate, interposer and glass-core processes with stack-specific validation.
- 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 limitationsResist resolution does not establish finished-circuit yield or repair existing metal shorts.
What to prepareBLNKK suggests preparing target line/space, stackup, surface condition, film-thickness needs and current exposure/development steps.
Confirm with the supplierConfirm grades, lamination/exposure/development windows and compatibility with plating, stripping and adjacent materials.
- Public evidence
- The TA page documents fine patterns, double-sided processing and exposure compatibility, without a complete grade-specific process window.
