Multicore® LF600 Lead-Free Solder Paste from Henkel
Irvine,CA — Henkel has introduced a new advanced lead-free solder paste material designed for the ultimate in manufacturing flexibility and superior performance regardless of regional climatic conditions.

Called Multicore LF600, the new soldering paste is a halide-free, no-clean Pb-free solder paste which has been formulated for excellent humidity resistance and is therefore especially suitable for varying manufacturing climates, enabling multi-national firms to qualify and deploy the material globally with the guarantee of consistent results. These characteristics allow for superior printing and reflow performance even in regions where temperatures are upwards of 30°C (86°F) with 80 percent relative humidity. The formulation utilizes a new activator chemistry which combines excellent coalescence with ultra-low voiding to deliver excellent long-term, in-field reliability results. In addition, the material has been designed with an innovative gelling technology that means zero hot slump and therefore, eliminates any issues with mid-chip solder beading.

According to the company, the new paste provides exceptional ease-of-use characteristics which translate to tremendous process efficiency and manufacturing flexibility. The material's highly stable solvent system delivers an unusually long open time of 24 hours and an abandon time of four hours, eliminating material waste and enabling continuous cycling for up to 24 hours with no degradation in print quality. This very broad process window for both reflow and printing as well as superior solderability over a wide range of reflow profiles in both air and nitrogen gives assemblers a multitude of options from which to choose.

The lead-free solder paste is available for stencil printing down to 0.4mm pitch QFP and 0.4mm CSP devices and is highly effective on a wide range of surface finishes including Ni/Au, Immersion Sn, Immersion Ag and OSP Copper.
