FL250D is a low voiding, no-clean solder paste specifically designed for maximum robustness in reflow profiling and stencil printing. Capable of fine feature printing with Type 3 (-325/+500 mesh) powder at print speeds up to 200 mm/sec (8 in/sec) along with a wide process window and long idle times makes the FL250D the premium paste choice for high- and low-volume manufacturing alike.
