Ultra C vac narrow-gap flux cleaning
ACM Research · Process equipment and thermal control
- Purpose
- Evaluate flux residues in narrow post-reflow gaps before selecting a pre-underfill cleaning process.
- Technical approach
- Ultra C vac uses vacuum to improve liquid wetting and gap access, with post-clean, drying and heating modules.
- Scope of use
- ACM targets FOWLP, chiplets and advanced 3D structures; settings depend on bump spacing, stand-off and materials.
- 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 limitationsSupplier zero-residue claims are not universal guarantees. Cleaning alone does not eliminate every underfill void; chemistry, pressure and drying compatibility need validation.
What to prepareBLNKK suggests preparing flux composition, reflow history, bump geometry, exposed materials, residue analyses and subsequent underfill results.
Confirm with the supplierConfirm chemistry and configuration, vacuum/temperature/time windows, drying and residue assessment, sample trials and material-damage checks.
- Public evidence
- The product page describes vacuum flux removal, narrow-gap use and equipment configuration, rather than validation of the user sample.
