Reballing and Ball Attach Services
BGA TEST & TECHNOLOGY has developed a reliable and repeatable process, in compliance with the objectives and requirements of IEC/TS62647, for re-balling and ball attach with the capability to convert Pb-free spheres to Eutectic Solder (Sn63Pb37) or High Lead solder (Sn10Pb90) spheres for Military, Aerospace, and other High-Reliability Electronic Assemblies.
This process will also work in reverse to convert tin-lead spheres to Pb-free (SAC305) spheres for many commercial applications with RoHS restrictions.
Brief Description of Process
After going through a QA gate upon arrival, incoming lots undergo the following steps:
- Incoming Inspection Process
- Moisture Removal-Pre-Bake
- De-balling: Automatic Using Six Axis ROBOT – Solder Sphere removal process
- Automated Cleaning: Trident LD system
- Inspection Post Deballing
- Moisture Removal-Post Deball
- Re-balling: Proprietary Solder Sphere attachment process
- Automated Cleaning: Trident LD DE fluxer system
- Drying Post Re-ball
- Baking to remove Moisture post Re-ball
- Final Inspection Process
- Marking If Required
- Marking Inspection
- Final Baking Per MSL of the Component
- Packaging and Shipping
Devices pass through the process cycle with strict quality and process control for repeatable and reliable results. Our Re-balling process has been proven to meet the requirements of ADHP (Aerospace, Defense, and High Performance) industries using the following qualification criteria:
- CSAM (Pre & Post Re-balling) – Analysis for De-lamination
- Ball Shear – Strength of ball adhesion
- Coplanarity Test
- Scanning Electron Microscope (SEM) – Post-Ball Shear Analysis
- Cleanliness – Ionic Contamination Analysis
- Electrical Testing (Pre & Post Re-balling)
