KEY-307 Halogen-Free, No-Clean, Lead-Free Flux

Product Highlights

Features

• KEY-307 halogen-free, no-clean, lead-free flux offers excellent solderability, producing full, bright solder joints with good solder penetration and uniform tin application. It meets the soldering requirements of various lead-free solders and is an ideal no-clean flux for use with lead-free solders.
• It effectively reduces the surface tension of lead-free solder, improving its fluidity and solderability.
• It has strong wetting power and good tin penetration through holes, which can effectively make up for the poor tin penetration of lead-free solder.
• The weld residue is evenly spread, has a good finish, and exhibits superior electrical reliability.
• It does not contain RoHS or other prohibited substances and is an environmentally friendly flux.

Scope of application

This product is compatible with various lead-free solders and is widely used in the electronics industry, including power supplies, computer motherboards, graphics cards, communication equipment, audio-visual equipment, refrigeration equipment, and medical equipment. It can be applied using spraying, dipping, and foaming processes.

Precautions

After opening and taking out the portion to use, the cap must be tightly closed to prevent solvent evaporation and changes in specific gravity.

Used flux should not be stored in the same container as unused flux. After opening the flux container, if there is any flux remaining, it should not be left exposed to air; the cap should be tightened as soon as possible.

The container for flux must be kept clean to prevent dirt and other substances from mixing into the flux and affecting its quality.

For electronic products with special requirements, it is recommended to conduct relevant compatibility tests.

For safety precautions and other details, please refer to the product's MSDS.
