IPC- Association Connecting Electronics Industries® today announced the U.S. Printed Wiring Board Industry Book-to-Bill Ratio for August 2001 was 0.94.

Sales billed (shipments) in August 2001 decreased 36.5% over August 2000 and orders booked decreased 50.7% over August 2000.

Compared to 2000, bookings of PWBs are down 48.1% year-to-date, while shipments of PWBs are down 22.8% year-to-date.

The ratio is calculated by averaging the number of orders booked over the past three months and dividing by the average sales billed during the same period.

The information is based on data provided by the 84 rigid and flexible PWB manufacturers participating in IPC's monthly Statistical Program. These companies represent over 48% of the U.S. domestic printed wiring board market. IPC publishes the book-to-bill each month. (Statistics for the previous month are not available until the last week of the following month.) For more information, contact Clint Gendusa at the IPC, 847-597-2871 or e-mail clintgendusa@ipc.org.
