水位监测报警系统原理

摘要:本水位监测报警器使用5V低压直流电源(也可以用3节5号电池代替)就可以对5~15厘米的水位进行监测,用LED显示和数码管显示水位,并可以对不再此范围内的水位发出报警。主要采用CD4066、74LS86、74LS32、CD4511芯片,再加上数码管、蜂鸣器、发光二极管、电阻这些器件组成一个简单而灵敏的监测报警 ...

PCB Design Considerations and Guidelines for 0.4mm and 0.5mm WLPs

Abstract: Using a wafer-level package (WLP) can reduce the overall size and cost of your solution.However when using a WLP IC, the printed circuit board (PCB) layout can become more complex and, ifnot carefully planned, result in an unreliable design. This article presents some ...
