DKL Clearflow 300 Flux
IPC-Compliant Low Residue Flux for Electronics Assembly
Clearflow 300 is a high-reliability, low-solids no-clean solder flux designed for modern electronics manufacturing. This IPC-compliant low residue flux for electronics assembly delivers exceptional performance with minimal, non-corrosive residues that require no post-solder cleaning. Engineered for wave soldering, foam fluxing, spray applications, and rework across through-hole, SMT, and mixed-technology assemblies.

Minimal Residue Performance
No-clean – Tack-free – Non-corrosive
Advanced low-solids formulation leaves benign, non-tacky residues that are safe on copper alloys. Clearflow 300 is designed to exceed the IPC J-STD-004B requirements for soldering fluxes, ensuring long-term reliability without cleaning.
- ✅ IPC-SF-818 & Bellcore TR-NWT-000078 compliant
- ✅ High surface insulation resistance
- ✅ No degradation over service life
