IPC -- Association Connecting Electronics Industries today announced the US Printed Wiring Board Industry Book-to-Bill Ratio for December was 1.05, up from the November ratio of 1.01.

Sales billed (shipments) in December increased 5.0% over December 1998 and orders booked increased 14.0% over December 1998.

Compared to 1998, bookings of PWBs were up 6.8% for the year, while shipments of PWBs were up 6.9%.

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

The information is based on data provided by the 90 rigid and flexible PWB manufacturers participating in IPC’s monthly Statistical Program. These companies represent 47% of the US 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 Dan Green at the IPC, 847-597-2871.
