Product Overview

Kester TSF-6592HF is a no clean paste flux designed as a lead-free solution for an array of lead free interconnect applications such as flip chip attach, sphere or ball attach, rework/repair of CSPs, BGAs, SMDs, or any lead-free soldering application that requires a very tacky flux. It is optimized for consistent high speed printing applications.


  • Bright shiny solder joints with clear residues
  • Aggressive flux on various substrates such as OSP-Cu, immersion finishes and ENIG
