Dow Electronic Materials Launches Silveron MF 100
September 10, 2009 | Business WireEstimated reading time: 2 minutes
Dow Electronic Materials introduces Silveron MF 100 autocatalytic silver and Aurolectroless SMT immersion gold for ASIG (autocatalytic silver immersion gold) final finish process for the PCB industry. The company has signed an agreement with Polymer Kompositer AB to become the global distributor for the ASIG final finish process, excluding UK and Nordic countries. Silveron MF 100 autocatalytic silver and Aurolectroless SMT immersion gold offer board fabricators, assemblers and OEMs improvements in solderability, shelf life, wire bonding and reliability due to the unique, dense, pore free silver deposit.
SilveronTM MF 100 autocatalytic silver can be used for reflow or wave solder assembly, and with Aurolectroless SMT gold for wire bonding. It offers many advantages over current solderable finish alternatives:
- Outstanding shelf life and solderability: Due to the autocatalytic nature of the silver bath, any thickness of silver can be achieved with a dense, crystalline, pore-free deposit, showing excellent shelf life and solderability due to prevention of copper migration to the surface through pores.
- Improved reliability: The fast intermetallic formation during soldering brings improved reliability due to lower soldering temperatures and time compared to nickel based final finishes, as well as avoiding potentially brittle intermetallic compounds formed with nickel based finishes when used with lead-free solders.
- Excellent conductivity: The excellent conductivity of the silver makes this the logical choice for high frequency applications, whilst gold or aluminium wire bonding shows exceptional bond strengths when using the complete ASIG process.
"Driven by changes to board design, component design and pitch, lead-free assembly and many other evolving variables, the demand for improved multifunctional, high reliability finishes is very real," said Bob Ferguson, Global General Manager for Dow Electronic Materials. "The introduction of Silveron MF 100 satisfies this demand. Innovative silver technology created by Polymer Kompositer, coupled with the global reach and market position of Dow Electronic Materials, creates exciting opportunities in the evolving PCB final finishes market."
