Kester Introduces EnviroMarkTM 923 Lead-Free Halogen-Free No-Clean Solder Paste at NEPCON China, Shanghai.

Apr 07, 2008

ITASCA, IL � February 29, 2008 � Kester announces it will showcase EnviroMark 923 (EM923), a halogen-free, RoHS Compliant lead-free no-clean solder paste, in booth 2C04 at the upcoming NEPCON China/EMT China 2008 exhibition and conference -scheduled to take place April 8-11, 2008 in Shanghai, PR China.

EM923 a lead-free and halogen-free solder paste contains state-of-the-art advantages for high-reliability and low-defect assembly and solidifies Kester�s commitment to be the global benchmark in no-clean lead-free and halogen-free solder paste. EM923 has been developed with unique flux chemistry system which has no intentionally added halogens (Chlorine, Bromine) or halides and yet providing superior solderability as compared to conventional halogenated/ halide-based solder paste systems. EM923 has been tested and conforms to IEC 61249-2-21, IPC-4101B and JPCA-ES-01-2003 halogen-free requirements, with no chlorine and bromine detected.

Kester�s EM923 offers numerous advantages over other solder pastes such as ultra-low voiding characteristics, lighter flux residue color, shiny joints and excellent solderability on all typical component and board finishes, and easier residue penetration.

The lead-free paste also provides a net improvement over products currently available to the market today. Its excellent print characteristic to 0.4 mm pitch, stable tack and stencil life with long idle time between prints ensure a reduction in print defects and paste waste.

The enhanced chemistry in the flux provides the necessary cold and hot slump resistance that is essential in a lead-free reflow thermal profile. The improvements in chemistry reduce potential defects such as bridging, solder balls and tombstoning while delivering superior activity to ensure good solderability of all common lead-free finishes.

Kester�s booth will be the best source for lead-free and halogen-free information at NEPCON China/EMT China 2008. Kester will also be featuring numerous other products from its Lead-Free Solutions portfolio to help companies achieve reliable lead-free. Among products being featured will be low Silver lead-free products and halogen-free solder cored wire.

As always, Kester's global lead-free team of technical engineers will be present to answer all lead-free and halogen-free questions that companies may have about these assembly. Be sure to stop by West Hall, booth 2C04 for more information.
