Page 27 SHENMAO: New Solder Paste for SMT Assembly
San Jose, CA —SHENMAO America, Inc., provides a variety of solder paste products for SMT assembly, in- cluding tin-lead, lead-free, water-sol- uble, package-on-package, low-tem- perature, and halogen-free solder paste.
SHENMAO offers tin-lead sol-
der pastes made from high-purity metal. This solder paste is produced with the strictest production and quality control resulting in reason- ably priced product with high quali- ty. The tin-lead solder paste accom- modates high print speed of up to 4.7 in./s (120 mm/s), excellent wettabili- ty, low voiding, reflow with or with- out nitrogen, over eight hours of stencil life, and an extended tack time of greater than 12 hours. With a sub-license from Fuji
Electronic Company, SHENMAO of- fers halide-containing and halide-free fluxes for lead-free solder alloys. This product exhibits excellent wettability, low voiding, over eight hours of stencil life, an extended tack time of greater than 12 hours, and a high print speed of up to 4.7 in./s (120 mm/s). SHENMAO has a full line of water-soluble fluxes and water solu-
Nathan Trotter Introduces NT100Ge Alloy
Coatesville, PA — Nathan Trotter has introduced a new line of solder products, NT100Ge, designed as a re- placement for SN100C® now that the related patent has expired. Produced using the same chemi-
cal composition as the solder alloy marketed as SN100C by Nihon Supe- rior and its licensees, NT100Ge is a high-quality, low-cost alternative to silver-bearing solder. The eutectic tin- copper-nickel alloy creates a shiny, smooth, robust interconnect for a wide range of electronics assembly require- ments. With a melting temperature of 441°F (227.2°C), NT100Ge is compati- ble with all wave and selective solder equipment. Similar to the effect of phospho-
rus in Sn63 alloys, the small addition of germanium in NT100Ge serves as a deoxidant, which keeps drossing to a minimum. For PCB fabrication appli- cations, such as the hot air solder lev- eling (HASL) process during which copper levels increase, NT100GeX pro- vides a low-copper solder solution. NT100Ge can be used as a drop-
in replacement for any existing 99C or SN100C solder bath, without the need for pot dumps or swaps. Once NT100Ge is in use, Nathan Trotter of- fers free, unlimited solder analysis to help maintain J-STD specifications and an optimal soldering process. NT100Ge is available as extruded 2.2 lb (1 kg) tri-bar, 7 lb (3.2 kg) feeder
bar, and solid wire on spools. Contact: Nathan Trotter & Co. Inc., 241 W. Stewart Huston Drive,

ble solder paste for SMT and IC packaging applications. The compa- ny offers halide and halide-free flux- es for tin-lead and lead-free solder al- loys. Their water soluble solder paste formulas have been proven to pro- vide an exceptional shell life, stencil life, wettability, and cleanability. The company also offers pack-
age-on-package solder paste products for high-density and advanced pack- age technology. This product is excel- lent for PoP applications. The formu- la has been shown to have better wettability and solderability, as well as lower voiding, than many other similar products on the market. SHENMAO has developed a high-quality low-temperature solder
paste for SMT devices. This solder paste has been qualified by a third- party organization to be highly effec- tive for SMT assembly. The melting point for this low-temperature solder paste is 280.4°F (138°C).
SHENMAO’s lead- and halo-
gen-free solder paste has been subli- censed from Fuji Electronic Compa- ny. These halide-free fluxes for lead- free solder alloys conform to RoHS law, allowing customers to comfort- ably use lead-free products. The halogen-free solder paste offers low voiding, print speed of up to 4.7 in./s (120 mm/s), over eight hours of sten- cil life, extended tack time of greater than 12 hours, and excellent wetta-
bility. Contact: Contact: SHENMAO America, Inc., 2156 Ringwood Av-
