ALPHA® EF-2210-TF is a VOC-Free, halide-free, rosin/resin-free, low solids no-clean flux which is among one of the highest activity VOC-free fluxes promoting defect-free soldering. ALPHA® EF-2210-TF is designed to be a drop-in replacement for ALPHA® EF-2210 for any user wishing to use a NPE/OPE-Free formulation. ALPHA® EF-2210-TF is formulated with a proprietary mixture of organic activators which deliver excellent wetting and top-side hole filling, even with OSP coated bare copper boards which have undergone prior thermal excursions. Several proprietary additives are also included into the flux which act to reduce the surface tension between the solder mask and the solder, thereby dramatically reducing the tendency of solderball formation. The formulation of ALPHA® EF-2210-TF is also designed to be more thermally stable; thereby, reducing the occurrence of solder bridging.
