Solder Formulations
No Clean (NC) NC ux consists of rosin, solvent, and a small amount of activator. NC
ux typically has low-to-moderate activity and is suited to easily solderable surfaces.
IPC classication is usually ROL0 or ROL1. NC residue is clear, hard, non-corrosive,
non-conductive, and designed to be left on many types of assemblies. Residue may be
removed with an appropriate solvent. Some, but not all, NC uxes are more difcult to
remove than RMA uxes.
Rosin (R) R ux consists of rosin and solvent. Rosin ux has very low activity
and is suitable only for easy-to-solder surfaces. IPC classication is ROL0. R residue
is hard, non-corrosive, non-conductive, and may be left on. Residue may be removed
with an appropriate solvent.
Rosin Mildly Activated (RMA) RMA ux consists of rosin, solvent, and a small
amount of activator. Most RMA ux is fairly low in activity and best suited to easily
solderable surfaces. IPC classication is usually ROL0, ROL1, ROM0, or ROM1. RMA
ux residue is clear and soft. Most are non-corrosive and non-conductive. Many RMA
uxes pass SIR testing as a NC ux. Residue may be removed with an appropriate
solvent.
Rosin Activated (RA) RA ux consists of rosin, solvent, and aggressive activators.
RA ux has similar and higher activity than RMA for moderately and highly oxidized
surfaces. IPC classication is usually ROM0, ROM1, ROH0, or ROH1. In the absence
of testing to prove otherwise, RA ux residue is assumed to be corrosive. Assemblies
sensitive to corrosion or the possibility of electrical conduction through the residue
should be cleaned as soon as possible after assembly. Residue may be removed with
an appropriate solvent.
Water Soluble (WS) WS ux consists of activators, thixotrope, and solvent.
WS ux comes in a wide range of activity levels, from no activity to extremely
high activity for soldering to even the most difcult surfaces, such as stainless
steel. IPC classication normally starts with OR for organic. They come in
L, M, H activity levels and halide content of 0 or 1. By denition, residue
may be removed with water.

Thermal Compounds
Thermal Compounds
Non-silicone thermal compounds are used in a wide range of electronic and
electromechanical applications because they are resistant to thermal cycling
degredation. Thermal compounds are formulated to provide excellent heat transfer.
They are non-hazardous, and are RoHS and REACH compliant (lead-free). Their long
shelf-life stability ensures that they will not dry, harden, or melt in normal use.
For challenging applications, thermal compounds are available with specialty features.
Choosing the best thermal compound requires some understanding of the mechanics
of heat transfer and how the thickness of the thermal compound layer, the bond line
thickness, inuences product choice.
