PCB design is to use EDA tools such as Allegro, PADS, Mentor, AD, etc. according to the circuit schematic diagram for layout and wiring, so as to realize the function of hardware circuit. Excellent PCB design engineers should not only be proficient in EDA software, but also know the circuit principle, SIPIEMC knowledge, have a […]

As far as the current development status and trend of international electronic circuits are concerned, the development prospect of PCB is very broad, but we will inevitably encounter some mistakes in the process of PCB design. This article will show you the development prospect of PCB and some common mistakes. Will you make these mistakes? […]

Basic requirements of wiring in high-speed PCB design (1) the outlet of rectangular pad of 1)QFP, SOP, etc. package should be led out from the PIN center (generally, shape is used). (2) The distance from the wiring to the board edge is not less than 20MIL. ) (3) Other network vias and surface wiring are […]

Besides the selection of components and circuit design, good printed circuit board (PCB) design is also a very important factor in electromagnetic compatibility. The key of PCB design is to minimize the reflow area and make the reflow path flow in the designed direction. The most common return current problems come from cracks in the […]

MCU is just the beginning … The cost and time-to-market requirements of entry-level MCU design are becoming more and more urgent. With the development of embedded software becoming the biggest contributor, MCU development kit must provide the same high-level value and usability as MCU. At present, designers demand powerful, simple, low-cost or, in some cases, […]
