PTI wafer bumping services
Powertech Technology Inc. (PTI) · Process equipment and thermal control
- Purpose
- Bump-height assessment needs defined formation targets and comparisons across wafer locations.
- Technical approach
- PTI forms lead-free solder bumps or copper pillars on wafer pads for subsequent flip-chip attachment.
- Scope of use
- Candidate designs need compatible pads, passivation, UBM and geometry under supplier design rules.
- 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 limitationsPublished pitch/height capabilities do not guarantee whole-wafer uniformity. Formation is not height metrology or repair of existing defective bumps.
What to prepareBLNKK suggests preparing wafer/pad data, UBM/passivation, target pitch/diameter/height, sampling locations and baseline height maps.
Confirm with the supplierConfirm geometry-specific rules, formation/acceptance conditions, measurement definitions and sampling; discuss location variation and assembly requirements.
- Public evidence
- PTI separately lists solder-bump and copper-pillar pitch/height capabilities and production experience.
