1976年以来，由于计算机、通信设备和消费类电子产品使用集成电路（IC）的数量不断增加，IC的销售量已增加了4倍。在所有IC产品中，98％为塑封微电路。塑封微电路自60年代推出以来，由于其单件成本低、尺寸小、重量轻以及可大量生产，因此越来越受到设备制造商的青睐。随着塑封 Since 1976, sales of ICs have tripled due to the growing use of integrated circuits (ICs) in computers, communications equipment and consumer electronics. 98% of all IC products are plastic microcircuits. Since its introduction in the 1960s, plastic encapsulated microcircuits have been increasingly favored by equipment manufacturers due to their low cost per piece, small size, light weight, and mass production.
