Specification in details
TF LF-01 Tacky paste flux Introduction:
TF HF-01,tacky Paste Fluxes (TF) are designed to meet and exceed industry standards. It is RoHS standars,halogen- free type of tacky flux. TF LF-01 Tacky paste fluxare used for general touch-up and rework of PCBs, and for the attachment of spheres to BGA and m BGA packages. Operations such as soldering Flip Chip components to various PCB substrates also use TF. TF LF-01 Tacky paste fluxis available in water soluble, no-clean and RMA formulations and can be dot dispensed, screen printed or stencil printed. Available in 10cc syringe; 100g jars; with other sizes available upon request.
