The US Semiconductor Industry Association’s book-to-bill ratio rose to 1.06 in October from a revised 1.04 in September – and there was restrained rejoicing in Santa Clara county because this was the first time since 1983 that the figure for October had been at parity or better. The ratio was nevertheless down on the 1.09 for August – but then, says the Association, comparatively few people order chips in October. Average monthly orders for the three months to October were $981.7m, up 3% on the average figure for the three months to September, and up 38.8% on the figure for October 1986. Shipments in October were $876.5m, down 13.7% on the September figure but up 57.7% on the figure for October 1986. Average monthly shipments for the three months to October came out at $922.8m.
