Kester is proud to announce the launch of SF800-LR. SF800-LR  is a zero-halogen, low-residue, low-solids, organic based liquid flux designed specifically for tabbing and stringing applications. The formulation delivers excellent solderability in module assembly processes utilizing conduction, IR and convection reflow. It is formulated to deliver minimum flux residue thus eliminating post cleaning after soldering. Cells are dry and cosmetically clean as they exit the tabber and stringer equipment. SF800-LR provides excellent solderability on all type of metalizations. The formulation of SF800-LR is also designed to deliver excellent peel force that result in long term stability of the solder joints.
