  2. How do you go about designing your own PCB? The ins and outs of PCB design are way too in depth to get into here, but if you really want to get started, here are some pointers: 1. Find a CAD package: there are a lot of low-cost or free options out there on the market for PCB design. Things to consider when choosing a package: 2. Community support: are there a lot of people using the package? The more people using it, the more likely you are to find ready-made libraries with the parts you need. 3. Ease-of-use: if it’s painful to use it, you won’t. 4.
  3. Q: At a fixed board size, if the design need to accommodate more functionality, they often need to increase the density of PCB traces, but this can lead to mutual interference traces enhanced while the traces are too small to make impedance can not be reduced, may I ask what skill at high speed (> 100MHz) high density PCB design? A: in the high-speed high-density PCB design, the crosstalk (crosstalkinterference) really should pay special attention because of its timing (timing) and signal integrity sex (signalintegrity) has a great influence. Here are a few caveats: 1. Continuous c
