Cleaning:
TF LF-01 Tacky paste fluxis a no-clean chemistry. The residues do not need to be removed for typical applications. If
residue removal is required, call our Technical Support.

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.

Application:
THF-01 Tacky paste fluxis 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.TF LF-01 Tacky paste fluxalso can be used for some lead free solder wire,which can achive the better welding effect.

Application notes:
Standard Applications:
TF LF-01 Tacky paste fluxis designed for stencil/screen printing, rotating drum, slide fluxers and/or syringe applications.
Great for rework applications on all PCB packages of various electronic devices. TF LF-01 Tacky paste fluxis great for rework applications on all PCB packages.
TF LF-01 Tacky paste fluxcan be used in BGA/PGA sphere/pin attachment vehicle or for repair and reballing/repinning. This flux works on flip chip, chip scale package and flip chip bumping sites assemblies as a soldering paste flux.

SHENZHEN BBIEN TECHNOLOGY LIMITED TF LF-01 Tacky paste flux could be classified as can/bottle packing and syringe packing type.
Each can/bottle holds the tacky pastes flux is 100g;
Each syringe can load the tacky paste flux is 30g or 10CC
The packing materials can be separated into inner layer of a bubble box and outer package of a paper carton so as to better secure for shipping and transportation.
