The NTI-100 list for 2011 was greatly influenced by exchange rates. Taiwanese fabricators continued to make gains, followed by Japanese manufacturers. Some names disappeared because they were purchased; their sales are included in the acquiring firm’s results. Some disappeared because they did poorly. Several fabricators, particularly Japanese firms, made it because of exchange rates.
As usual, the author is not almighty and is certain that there are many errors. Some companies that should be on the list may be missing. He assumes full responsibility for any errors. He wishes to express his gratitude to those PCB makers that provided him valuable data.
Exchange rates. Currency values played a role in certain companies’ performance. Table 1 lists the average exchange rates of major currencies against the US dollar.
Assumptions. All acquisitions that took place during 2011 are  assumed to have taken place on Jan 1, 2011. In the cases of flexible  circuit manufacturers (FPC), the assembly value is included because it  is extremely difficult to separate bare board sales from total revenues.  Therefore, the rankings are relative, not absolute. Finally, a large  portion of revenues of Taiwan, Japanese and US makers comes from  overseas operations, and therefore involves double conversions. The  author has no knowledge of what exchange rates Taiwanese makers, for  example, used to convert output in RMB into NT dollars to report  consolidated revenues.
Entries by country or region. There  are 104 companies on the 2011 NTI-100 list. There are more Japanese  makers than Taiwanese because of a 10% increase from 2010 to 2011 in  value of the Japanese yen against the US dollar. Several Japanese makers  would not have made it had the 2010 exchange rate remained constant.

Table 3 lists the 2011 NTI-100. Although comments are included in the table, more extensive comments on certain fabricators are below.
