There are many factors that engineers need to consider. This article organizes some detailed issues that need attention in PCB layout. Let’s check if you are aware of them! 01 Layout of Special Components Heating components should be placed in a location conducive to heat dissipation, such as the edge of the PCB, and away … Read more
I am Lao Wen, an embedded engineer who loves learning.Follow me to become even better together! I remember when I first started working, a master told me that if you are not familiar with longjmp and setjmp, you should not call yourself a C language expert. At that time, I was half-convinced, but to move … Read more
