Crown reaches RoHS compliancy milestone

test 19 December 2006

US: In the wake of Shure’s recent announcement that it is expecting to become RoHS compliant on a global level early in 2007, Crown International has confirmed that a majority of its amplifier ranges now meet the terms of the EU directive, writes David Davies.

According to the Indiana-based manufacturer, eight of its eleven amplifier lines currently in production – including the CDi, Commercial Audio and CTs series – now satisfy the criteria defined by the RoHS edict. The same can be said of all the company’s PIP modules.

"Crown has always demonstrated a commitment to environmentally-friendly manufacturing," commented Larry Coburn, Crown’s senior vice-president of manufacturing. "Years ago we changed our paints to solvent-free powder coating and, more recently, changed our solder flux to eliminate the need for harsh solvents. So RoHS was a natural progression for us."

The move has not been without its challenges, beginning with the introduction of new lead-free processes and subsequent performance tests. There was also the small matter of contacting all suppliers so they could certify that their components met RoHS terms. Noted Coburn: "That alone entailed over 10,000 parts! As far as the factory was concerned, we upgraded both of our assembly lines to handle higher temperatures and new lead-free solder. We also worked for over a year in advance with dedicated resources to make this transition a smooth one, and spent considerable time with many recognised consultants and our automotive group to ensure success."
