Frequently asked questions
Is this flux suitable for lead-free soldering?
Yes, it is listed as lead-free and halogen-free, so it is intended for lead-free assembly and rework. Use it with the solder alloy and temperature profile your process requires.
How should I apply the paste before soldering?
Apply a thin, even layer to the pads or joint before heating. Because it is a paste with a defined viscosity, it stays where it is placed, which helps with fine-pitch pads.
