Dealing with high oxidation or old assembly parts is way more productive when instead of a "go-to" ROL0 flux an engineer summons a specialty high activity flux - NWS. 

NWS series is a New Water Soluble formulation with highly desirable industrial properties - efficient oxides mitigation, sheer wetting capabilities, and high tolerance to many different surfaces.

NWS uses innovative polymer-dendrimer activator coupled with a highly stable clean rinsing binder resulting in high activity.

While H1/M1 flux can be naturally outgassing, risk of voiding doesn't affect solder spheres because a sphere is already formed, also since a chip is not yet on a board - standoff restrictions do not apply.

NWS is also very efficient for desoldering and at the same time prepares work area for oxide-free soldering - two in one shot.

NWS is available as a standard ORM1 flux NWS-4200-TF, lead-free ORH1 flux NWS-4200-LF-TF and as an enhanced ORH1 formulations NWS-4200-4-TF and NWS-4200-6-TF with 4% an 6% chlorides respectively. These modifications provide maximum impact and increase wetting and prepping for metals even on highly oxidized boards and old parts.

Besides highly successful organic-based formulations NWS lineup also features resin based (REM1) universal flux - NWS-4400-HA/LF-TF.

NWS - Winning In Cleaning

As a rule of thumb removing M1/H1 flux residues is paramount, however it is an easy task - use warm de-ionized water at 40-60°C with recommended water pressure of 30-50 PSI – NWS residue is completely water soluble!

Storage and Handling

Tacky flux should be stored at room temperature (20-25 °C). Syringes and cartridges should be stored vertically with the dispensing tip down. Properly stored tacky flux has a 12 month shelf life.
