Key Features & Benefits
High Purity & RoHS Compliance
Formulated for electronics with RoHS certificate compliance—safe for use on consumer and industrial PCBs.
Non-Corrosive, Neutral pH
Neutral pH avoids post-solder corrosion; rosin residues are non-conductive when dry, protecting circuit integrity.
Oxidation Resistance
High-boiling components reduce oxidation during solder and reflow processes, producing smooth, shiny joints.
No Harsh Chemicals
Lead-free and free from zinc chloride and ammonium chloride—low odor and reduced volatility for safer use.
Recommended Use Cases
- Through-hole and surface-mount soldering on tin-lead and lead-free alloys.
- Precision rework, soldering of gold/silver/copper contacts, and connector assembly.
- Desoldering and reflow tasks where low-residue and non-corrosive flux is required.
How to Use
- Clean the board or contact area from gross contamination and oils.
- Apply a few drops of the RMA flux to the joint area using the dropper—sufficient immersion improves wetting.
- Solder as usual with appropriate temperature settings for the alloy being used.
- After soldering, inspect joints; rosin residues are generally non-corrosive but may be removed with IPA if desired.
FAQ
- Is this flux corrosive?
- No. The CP-4023 formulation is non-corrosive and maintains a neutral pH after soldering.
- Can I use this with lead-free solder?
- Yes. The flux is effective on tin-lead and lead-free alloys as well as on gold, silver and copper contacts.
- Does the flux contain hazardous activators?
- It is a Rosin Mildly Activated (RMA) formulation that is free from zinc chloride and ammonium chloride and is lead-free.
