When designing a PCB, I found that many people, especially beginners, do not have a clear understanding of the layers in a PCB. Therefore, today let’s take a look at the differences between the various layers when using the software Altium Designer to create a board. 1. Signal Layer The signal layer is divided into … Read more
Soldering SMD components on a PCB is a true test of skill, with numerous chip pins and capacitors and resistors smaller than sand grains, issues like cold solder joints and short circuits frequently arise and are extremely difficult to detect. This requires high levels of technique and patience. More importantly, there are some small tips … Read more
Whether engineers or PCB manufacturers, they inevitably encounter PCB failures. The occurrence of these failures may lead to delays in product delivery, damage to the manufacturer’s reputation, and increased time and monetary costs. (Most importantly, it costs money.) Today, we mainly discuss PCB failure modes and solutions. (It is recommended to save for later viewing, … Read more
Although PCB manufacturing online has become very quick and cheap, with some manufacturers even offering free test board production, compared to making a test circuit board in “one minute“, sending out for board production still takes too long. For circuits that need testing, quick prototyping allows for rapid iteration to complete experimental circuits. The final … Read more
