ALPHA® SF828-MBB
Liquid Soldering Flux
Next-gen Photovoltaic tabbing flux for advanced multi-busbar PV interconnection, aimed at soldering small wire surface areas.
Contact UsProduct Overview
ALPHA SF828-MBB is a low-solids-content, alcohol-based, zero-rosin, no-clean liquid flux designed for most standard and multi-busbar Photovoltaics (PV) interconnections. ALPHA SF828-MBB contains a unique blend of ingredients that overcome the smaller surface area of wire (≤0.4mm) used in the ever-evolving multi-busbar technology to achieve excellent interconnections.
ALPHA SF828-MBB enables a wide process window and requires minimal heating before fluxing. It delivers excellent peel force, resulting in long-term reliability of the solder joints.
Product Features
Fast Wetting with Minimal or No Heating Prior to Wire Ribbon Dipping
Fast wetting with minimal or no heating before wire ribbon dipping, ensuring higher process efficiency.
Reduced Placement Slippage for Improved Production Yields
Less Residue
Less residue to support higher power transfer efficiency and reduce equipment maintenance.
Superb Adhesion and No Yellowing or Bubbling Across Different EVA Laminations
High Peel Strength and Long-Term Reliability
ALPHA SF828-MBB Delivers High Peel Strength and Long-Term Reliability
The high peel strength provided by ALPHA SF828-MBB ensures long-term reliability of the solder joints, contributing to long module life, good soldering yields, and satisfactory ribbon-cell interconnections.
Damp Heat Testing
Electroluminescence analysis of ALPHA SF828-MBB showed no color degradation or smudging of the flux layer. The soldering and bonds remain intact.
