NP545 SOLDER PASTE

Kester NP545 solder paste is a zero-halogen, lead-free, no-clean solder paste formula designed for consistency and repeatability. NP545 is extremely stable and has an unrefrigerated shelf life of 12 months with no print or solderability degradation. NP545 consistently delivers paste transfer efficiencies of 0.55 to 0.5AR. The paste is also fully capable of printing and reflowing 01005 components, even in air reflow, with minimal graping behavior. NP545 is classified as ROL0 under IPC JSTD-004 and ROM0 under IPC JSTD-004B.
