The Schematic Design Schematic design is preparatory work. For a simple board, if you are with skilled process, you can skip it. But for beginners, you must follow the process. On one hand, you can develop good habits, on the other hand we can avoid mistake by this way for complex circuits. When drawing the …

What is PCBA? PCBA is assembly of PCB. Various electronic devices are assembled on the circuit board by surface packaging process. Next is box assembly, which will assemble the assembled PCB with the shell to form the finished product. PCB blank board passes SMT upper part, then passes through the whole process of dip plug-in, …
John is a PCB engineer. He said, “It’s not easy to make PCBs according to the process. Just drill a hole to make components. It’s not difficult to make PCBs. What’s difficult is to check the faults after the PCBs are made. “ Whether it’s a personal enthusiast or an industry engineer, it’s a headache …

In PCB design, we always encounter this and that problem. This article summarizes 8 frequently asked questions you might come across. We discussed, and hope to help you. Q1: Two characteristic impedance formulas are often referred to: MicrostripZ={87 / [sqrt (Er +1.41)} ln [5.98H/ (0.8W+T)]W— The width of the lineT — The thickness of copper …
Printed circuit board design is based on circuit schematic diagram to realize the function required by circuit designer. PCB design mainly refers to layout design, which needs to consider the layout of external connection. When designing the PCB, it is important to note that each file should be connected as a whole at last, which …
Although semiconductor integration is becoming more and more high, many applications also have on-chip systems available at any time. And many powerful and open-box development boards can be easily obtained, but in many cases, the application of electronic products still need to use custom PCB. In one-time development, even a common PCB can play a …
printed circuit boards Introduction What’s PCB? PCB is a printed circuit board and one of the important parts of the electronics industry. Almost every kind of electronic equipment(electronic watches, calculators, computers, communication electronic equipment, military weapon systems, etc.,) are all need use PCB. It can make the electrical interconnection between the various components. And now …
We all know that the heat generated during the operation of electronic equipment causes the internal temperature of the equipment to rise rapidly. If the heat is not dissipated in time, the equipment will continue to heat up, the device will fail due to overheating, and the reliability of electronic equipment will decline. Therefore, it …
