Details are emerging of manufacturers facing disruption to their supply chain due to the earthquake in Japan.
Apple may have problems sourcing parts for its new iPad 2, analysts' research suggests.
Sony Ericsson has said that it would face similar problems with its mobile phones.
But supply shortages are likely to hit hard only in about three months, according Malcolm Penn, chief executive of research firm Future Horizons.
"This will start to bite home in a few weeks' time when the first shortages start to appear, and hit hard even further in about three months' time when the production that isn't being made today should have been coming online," he told the BBC.
