Hot-dipped-tin process offers path to increased market share in competitive times

One of the concerns of companies complying with lead-free manufacturing processes under the European ROHS (Restriction of Hazardous Substances) directive is the tin whiskers that can develop over time on tin plating. Trim pot manufacturer Bourns recently announced it was shifting its entire line to a new hot-dipped-tin process for the trim pots’ terminals. Bourns will no longer offer the old matte-finished parts because of the tin-whisker danger. Although the company made the change at the request of its customers, it won’t be passing the price increase on.

Emill Melliz, Bourns’ potentiometer product line manager, puts the price increase at between 5-7%. Why is Bourns eating this not-inconsiderable amount? They see it as a way to increase market share in a very competitive economy. Smart company.
