Multicore LF620 is a no-clean, halide-free, Pb-free solder paste that has a broad process window for printing, reflow and humidity resistance. Has a consistent print performance with minimal hot slump, even with temperatures of 86°F or more and relative humidity of 80%. Exhibits extremely low voiding in CSP via-in-pad joints, good coalescence and excellent solderability over a wide range of surface finishes, including Ni/Au, Immersion Sn, Immersion Ag and OSP copper. Has good printability at low or high speeds. Is well suited for the automotive sector. Delivers a high tack force for component stability during high-speed placement, an abandon time of four hours and a print work-life of up to 24 hours.
