MacDermid Alpha Electronics Solutions Liquid Solder Flux ALPHA ® EF-6038HF

Product Overview ALPHA EF-6038HF is a no-clean, alcohol-based, halogen-free flux that delivers ultra-low residue performance for high-reliability soldering. Ideal for standard to moderately complex PCB assemblies, the formulation combines enhanced thermal and oxidative stability with a broad process window and excellent hole-filling capability. The rosin-free chemistry leaves minimal to no residue, removes the need for post-soldering cleaning, and supports high pin testing yields. Product Features Ultra-low, non-tacky residue Delivers excellent cosmetic appearance and minimal interference with pin testing. Wide process window Enables flexible application across a range of assembly conditions. Excellent hole fill Improves electrical reliability and mechanical strength. SIR: IPC J-STD-004 A/B Compliant Supports long-term electrical reliability of finished assemblies. Halogen-free formulation Facilitates high-reliability assembly and environmentally responsible processing.
