缺芯的影响，随着对芯片的需求量持续增加，汽车、手机都出现缺芯的情况。半导体国产化进程加速，芯片不断渗透进消费者的日常生活中，目前汽车芯片相关已满负荷运转生产。
半导体行业国产化进程不断加强，近两年芯片供应不足问题依然严峻，各类产品推动了芯片需求的涨。白酒板块突破震荡箱体后再破前高，，短期涨较大，板块的短线形态较弱，形态没有很大好转。
回收ICSI电子元件再者，就是每一计数的时间是多久?一般我们取12M晶振时，一个周期刚好是1us，计数1000个就是1ms，这是因为标准的51单片机是12时钟周期的(STC有6时钟和1时钟方式)。那么，如果我们晶振是12M，就比较好算，如果是其它的，就用12去除好了。比如是6M的，那么就是12/6=2，每个计数是2us，那么你要定时1ms就只要计数500个即可以。定时器的初值跟定时器的工作方式，跟晶振频率都有关系。一个机器周期Tcy=晶振频率X12，计数次数N=定时时间t/机器周期Tcy，那么初值就X=65536-N，得出的数化成十六进制就行了。
