In yesterday’s tweet, we discussed the impact of the bit depth of microcontroller ADCs on measurement errors. It should be noted that the experiments mentioned in the tweet were merely for theoretical validation. As suggested by a netizen later: the performance of microcontroller ADCs (ENOB and non-linearity) can only be verified through experimental data when … Read more
1. Types of PCBs According to the number of circuit layers, PCBs can be classified into single-sided boards, double-sided boards, and multi-layer boards. Common multi-layer boards typically have 4 or 6 layers, while complex multi-layer boards can have dozens of layers. The following are the three main types of PCBs: 1. Single-Sided Boards Single-sided boards … Read more
When hardware engineers first encounter multi-layer PCBs, it can be quite overwhelming. With sometimes ten or more layers, the layout resembles a spider web. Are you still struggling? Today, I’ve created several internal structure diagrams of multi-layer PCBs, using 3D graphics to display various stacking structures of PCB internal architecture, helping you to see clearly. … Read more
Remember when I first did PCB Layout, multi-layer board prototyping costs were very high, and the delivery time was about seven or eight days. Due to cost and time considerations, I often only considered using double-sided boards for routing. Then, holding many design rules that would often “conflict” with each other or experience-based rules circulating … Read more
