WS159 Leaded Solder Paste
WS159 is a water soluble, leaded solder paste that is classified ORH0. WS159 was formulated to meet the requirements for reliable solder joints in PCB Assemblies along with a large operating window. Thus, WS159 was designed to provide humidity tolerance and excellent wetting. WS159 remains stable in a wide range of temperatures (65-85F) and relative humidity (25-65%RH). While maintaining a stable viscosity and exceptional cosmetics, WS159 exhibits low voiding characteristics. The residue for this product is easily visible and removable with warm water.
Excellent print volume consistency with surface area ratios (SAR) as low as 0.50 when used with the NanoSlic stencil technology
