"Dow brings to the PCB market not only the latest and most advanced products, but also an industry-leading understanding of technology and manufacturing requirements," said Helen Zhang, Global General Manager for Dow Electronic Materials. "This expertise, along with our extensive global footprint, is critical to our ability to work with our customers so they can achieve high yield and performance in their manufacturing processes. Our metallization technologies and the service we deliver with our products allow us to support a broad array of markets including telecom, military, aerospace, medical and photovoltaic."
At the IPC APEX EXPO, Dow will highlight two products for PCB final finish, in which the coating layer is created on the conductive pad surface to provide solderability, wire bonding and protection. A third product featured targets PCB electrolytic plating.
First, AUROLECTROLESS™ SMT 520 Immersion Gold Bath can substantially reduce operating costs with its low gold salt content (0.5g/L – 0.74g/L) without sacrificing performance. Producing uniform, fine-grained deposits of pure gold on metallic substrates, the bath is easy to control, has high tolerance to contaminants, and offers consistent performance over the bath life.
AUROLECTROLESS™ SMT 520 Immersion Gold Bath provides excellent deposit coverage to increase corrosion resistance during subsequent process steps and is suitable for both electroless nickel immersion gold (ENIG) and electroless nickel electroless palladium immersion gold (ENEPIG) applications.
Second, SILVERON™ MF 100 Electroless Silver is an innovative autocatalytic silver material composed of silver with anti-tarnish allowing it to achieve the performance capability of ENIG without the corrosion and ground plating associated with nickel. Offering a dense silver coating that prevents diffusion of copper to the silver surface to reduce the formation of copper oxide, SILVERON™ MF 100 Electroless Silver delivers strong solder joints, multiple reflow capabilities, excellent wire bonding capability and exceptional RF performance when compared to nickel.
The company's third featured product at the show is MICROFILLTM EVF Copper Via Fill targeting PCB electrolytic plating. Providing enhanced via filling at exceptionally low surface thicknesses, MICROFILL™ EVF Copper Via Fill is capable of simultaneous through-hole plating. Suitable for both high density interconnect (HDI) and integrated circuit (IC) substrate applications, it is compatible with both panel and pattern plating processing as well as soluble and insoluble anodes. MICROFILL™ EVF Copper Via Fill products are easily analyzed to deliver excellent reliability.
Other products to be featured include LITHOJET™ Products for primary imaging, CIRCUPOSIT™ 7800 Products for desmear and electroless copper applications in the packaging substrate industry and ENLIGHT™ Products including metallization and imaging offerings for the photovoltaic manufacturing process.
Dow Electronic Materials will be exhibiting in Booth #1249 at the IPC APEX EXPO, which will be held at the Mandalay Bay Resort & Convention Center in Las Vegas, Nevada, USA, from April 12 to 14, 2011.
