What flux should I use when replacing PCB components?

CircuitWorks® flux pens are available with a variety of fluxes to fit your specific shop requirements, including: no-clean, high temperature no-clean for lead-free soldering, rosin, and water soluble. Flux pens are an excellent way to dispense flux for benchtop soldering. You just hold the pen vertically and briefly depress the tip to start the liquid flow. This will saturate the tip of the pen with flux. Draw flux on the area to be soldered. Gently press the tip again when more flux is needed to keep the tip damp with flux.

Can I add my own flux to solder wick?

In a production or repair environment where the flux is specified and can’t be changed, or when an aqueous flux is needed, you can add your own flux to this type of braid. Unfluxed wick will not remove solder unless flux is added. Different types of fluxes are available in pen packaging, which is ideal for fluxing braid.


Ultimate Guide to Benchtop PCB Rework & Repair

The reality is that no soldering operation produces perfect assemblies every time. Even the highest quality components fail from time-to-time. That’s why understanding the best rework and repair methods and materials is so important for those who manufacture, maintain, or repair printed circ...

Why Flux Pens Make PCB Repair Easier

Flux is needed to prevent oxidation that tends to form when hot metals come in contact with the air. During printed circuit board repair and soldering, it's common to see liquid flux from the wave soldering equipment poured into jars and applied with an acid brush. More is better, right? W...
