TO BE SOLVED: To provide water-soluble flux for solder paste capable of preparing paste having excellent temporal stability of viscosity, which is paste excellent in fusibility, and capable of performing cleaning after reflow only by water; and to provide solder paste prepared by using flux.植...
Many water soluble paste fluxes are acidic. I would not leave it on my board one second longer than absolutely necessary. However, whether it is because of its potential corrosive effects or if its effective removal is reduced if left on too long, it will depend on the chemical makeup of ...
Product Data Sheet WS159 Water Soluble Paste INTRODUCTION WS159 water washable solder paste is designed to meet the requirements for reliable solder joints in PCB Assemblies. WS159 displays previously unseen levels of repeatability and consistency even in a wide range of temperatures (65-85°F) ...
These types of paste are generally high activation flux. Why use one or the other ? It depends on what you are making. If you need high reliability for a long term then it is a good idea to use a water soluble paste as it has high activation flux and after cleaning there will be ...
The traditional solder flux is formulated with rosin or epoxy resin as the base material, mixing with an active agent, thixotropic agent, solvent, and other substances. At present, two major factions of no-clean solder paste and water-soluble solder paste have been derived based on flux composi...
Water-soluble solder paste and soldering method PURPOSE: To provide a water-soluble solder paste which does not affect adversely a surface insulation resistance(SIR) of a circuit board. CONSTITUTION: This solder paste is comprised of solder powder, water-soluble flux (containing activ... CV Dodd...
