Stuff reports that the flow-on effects of the earthquake on Japanese companies which are responsible for the making of parts for cellphone assembly companies, may result in lower volume and profitability risks for the cellphone makers.

Nokia, for example, did warn that it could face disruptions in stock, but that the impact on earnings would be minimal.

Specific components which are affected include silicone wafers used to make microchips, and BT resin used for smartphones and tablets (80% of BT resin is made in Japan). Discrete optical components are largely manufactured in Japan as well.
