PCB设计问题集锦
问：PCB图中各种字符往往容易叠加在一起，或者相距很近，当板子布得很密时，情况更加严重。当我用Verify Design进行检查时，会产生错误，但这种错误可以忽略。往往这种错误很多，有几百个，将其他更重要的错误淹没了，如何使Verify Design会略掉这种错误，或者在众多的错误中快速找到重要的错误。 答 ...
电源技术 手持式高功率电池充电器
 
As the performance of many handheld devices approachesthat of laptop computers, design complexity also increases.Chief among them is thermal management—how doyou meet increasing performance demands while keepinga compact and small product cool in the user’s hand?For instance, ...
电源技术 为敏感电路提供过压和电源反接保护
 
What would happen if someone connected 24V to your12V circuits? If the power and ground lines were inadvertentlyreversed, would the circuits survive? Does yourapplication reside in a harsh environment, where the inputsupply can ring very high or even below ground? Evenif these events are ...
