PTI FCCSP/FCBGA flip-chip assembly services

Powertech Technology Inc. (PTI) · Process equipment and thermal control

Purpose: Compare flip-chip assembly conditions using actual bump/pad geometry to investigate solder bridging.
Technical approach: Bumps connect dies to substrates with package-specific underfill and molding configurations.
Scope of use: Evaluate FCCSP/FCBGA and ask about controlled comparison builds with supplier-approved configurations.
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
Service descriptions do not prove bridge-free yield or provide existing-bridge localization or repair.
What to prepare
BLNKK suggests preparing bump/pad dimensions and pitch, solder volume, placement, reflow/underfill steps and defect comparisons.
Confirm with the supplier
Confirm design rules, bump/underfill options, trial conditions and bridge-inspection/electrical-verification methods.
Public evidence: The page lists Cu pillars, lead-free bumps and CUF/MUF options, without bridge-validation results.
