There is no question that Japanese flexible circuit manufacturers have been leading the global market in both volume and technology. A dozen major Japanese manufacturers cover more than 50% of the global flex market.
The updated total forecast for the top four flex manufacturers (Nippon Mektron, Fujikura, Nitto Denko and Sumitomo Electric) is about 340 billion yen (approximately $2.9 billion) this year, and may represent more than a 40% share of the global market. Most of the manufacturers have been producing huge volumes of 50 micron-pitch fine trace and consumer rigid-flex. They have been installing state-of-the-art equipment in overseas sites, and can therefore be the price leaders in the market and maintain current margins.
The Japanese flex manufacturers have been experiencing slow demand since the summer of 2004. The market has been rebounding since the third quarter of 2005, but the total monthly shipments for manufacturers are still lower compared to the same months in 2004. Total revenue for 2005 will be 10% lower than 2004, but major manufacturers are optimistic that it will rebound this year.
While the exporting business is strong, Japanese manufacturers say that the major reason for the domestic decline has been the slow consumer market in Japan. The major manufacturers have aggressive investment plans this year, expecting continuous growth in the future. In 2005, the top four flex manufacturers will invest about 30-35 billion yen in the flex circuit business - money that will be used to expand manufacturing capacity, including the assembling of the circuits. This may help them keep the leadership position in the global market.
However, Japanese flex makers can't be optimistic about their margins. Domestic customers have been asking for price reductions to meet the cost down requirement for consumer products such as cellular phones and flat panel TVs. Manufacturers have not met these requirements since the seller's market two years ago; now they must contend with a buyer's market.
Another headache for Japanese manufacturers is pressure from Korean and Taiwanese manufacturers. These foreign flex manufacturers have been offering very aggressive prices for domestic customers in Japan, making it impossible for Japanese manufacturing management to relax.
