NP545 Solder Paste

Kester's NP545 is a no-clean, zero-halogen solder paste formula designed for consistency and repeatability. The NP545 consistently delivers paste transfer efficiencies of 0.55 AR to 0.50 AR. This paste is also fully capable of printing and reflowing 01005 components, even in air reflow, with minimal gapping behavior. NP545 is classified as ROL0 per IPC J-STD-004B.

The NP545 is available in lead-free and leaded alloys. The leaded alloy can be used in backward applications and is thus fully compatible for soldering complex lead-free component on SnPb assemblies.
