It used to work fine before, but I don't know since when, all the multi-layer pads in the PCB library became FULL STACK, resulting in a pad on the top layer and a hole on the bottom layer.

When designing a PCB (printed circuit board), one of the most basic issues to consider is how many wiring layers, ground planes, and power planes are needed to achieve the required functions of the ci
We all know that projects that are not connected to the Internet often no longer exist in today's smart home industry, so we must first configure the network for the development board.
The specific pr
Node voltage calculation【（V1-Vin-）/600】=【（Vin--V2)(600+10.2)】
【（V1-Vin+）/(600+10.2)】=【（Vin+-V2）/600】
By finding the values of Vin- and Vin+ respectively, we can get the sum of Vin- and Vin+,provided t
