TK83 Flux for electronics 50 ml

TK83 Flux with a capacity of 50 ml is a professional, liquid, moderately active flux that meets ISO 9454 type 1134 and J-STD-004 ROL0 standards. The preparation is a solution of rosin in alcohol, enriched with organic activators. The product was developed for advanced soldering processes of electronic circuits, ensuring optimal solder flow and high reliability of the connections made.

Key technical features

• Flux type: ISO 9454 type 1134 / J-STD-004 ROL0
• Physical state and appearance: Dark amber-colored liquid
• Odor: Characteristic alcoholic-resinous
• Density (at 20°C): 0.86 g/cm3
• Static activity (at 250°C): Spread area of Sn60Pb40 alloy is 250
• Working temperature: High soldering efficiency at temperatures up to 280°C
• Solubility: Activator insoluble in water, flux fully soluble in organic solvents

Application methods and cleaning

The flux is highly versatile in terms of application methods. The preparation can be applied to printed circuit boards using various methods: flux wave, spraying, foam, dipping, with a marker, and with a brush. An important parameter of TK83 flux is the lack of corrosive action of residues formed after soldering. This means that the product does not require mandatory removal from the board (no-clean properties). If the project specifications require a clean surface, residues can be easily and quickly washed off with isopropyl alcohol (IPA), ethyl alcohol, or a dedicated PCB cleaner.

Example applications

• Soldering and desoldering processes of components in surface-mount technology (SMD, BGA).
• Manual and precise tinning of electrical wire ends.
• Tinning of traces and solder pads on printed circuit boards.
• Restoration and recovery of original solderability of oxidized or old electronic components.
• Service and repair work on consumer electronics and assembly of prototype circuits.

Benefits

• Versatile applications - ideal for assembly and servicing of SMD and BGA components.
• Circuit safety - non-corrosive residue properties protect traces and delicate components from gradual degradation.
• High-temperature operation - the product provides high soldering efficiency at temperatures up to 280°C.
• Time savings - no need for mandatory board cleaning after the soldering process is complete.
• High work efficiency - effective and rapid wetting of soldered surfaces facilitates the formation of proper, durable solder joints.
• Convenient application - the optimal, fluid consistency allows precise flux dosing in hard-to-reach places on the board.
• Easy servicing - effortless solubility in commonly available organic solvents, which facilitates optional cleaning.
