Design of Mark Points in PCB Production 1. A mark point corresponding to the whole board must be located on the diagonal of the PCB’s long edge. For chips with an integrated circuit pin center distance of less than 0.65mm, there must be a corresponding mark point on the diagonal of the integrated circuit’s long … Read more
a) Small power supplies should prioritize copper pouring on signal layers, followed by connections through traces that meet current-carrying requirements; Small power supplies (those with relatively low current in PCB design) typically need to consider signal integrity and power distribution issues. During layout, priority should be given to copper pouring on signal layers (usually inner … Read more
(There are benefits at the end of the article, don’t miss out!) As electronic devices develop towards higher performance and smaller sizes, the precision and performance requirements for PCBs are also increasing. High multilayer PCBs can provide more routing layers, allowing for more complex and dense circuit designs, thus meeting the demands for high-frequency and … Read more
Flying probe testing is the best solution to some major electrical testing issues today. It replaces traditional test beds with probes, using multiple motor-driven electrical probes that can quickly move to contact the pins of devices and perform electrical measurements. During the production process of PCB boards, it is inevitable to encounter electrical defects such … Read more
Printed Circuit Boards (PCBs) are independent modules made up of interconnected electronic components, found in everyday electronic devices such as mobile phones, routers, and personal computers, as well as in complex systems like radars, missiles, and satellites. Their brilliant designs are often hidden by the device’s casing, and the genius behind the design is frequently … Read more
For those born in the 80s, the first encounter with gold fingers can be traced back quite a while, although at that time it was not understood what it was all about. The Nintendo Famicom and Little Tyrant game console cartridges connected electrically through gold fingers. Gold fingers (connecting fingers) are used in computer hardware, … Read more
PCB Copper Pour refers to the area filled with copper in a PCB layer. This layer can be on the top, bottom, or any internal layer of the PCB, and PCB copper pour can be used for grounding, reference, or to isolate specific components or circuits from the rest of the elements on that layer. … Read more

[Weiwenxin PCB] Part 1: Various Factors Affecting the Price of a PCB Board The price of PCBs has always puzzled many purchasers. Many people also wonder how these prices are calculated when placing orders online. Let’s discuss the components of PCB pricing. 1 The Diversity of Prices Caused by Different Materials Used in PCBs For … Read more
Unlike the production of general robots, creating soft robots is very challenging because structural, power supply, and control system changes must be made accordingly. More difficult is the need to reduce their size, especially for the part responsible for the movement control of the soft robot. Researchers from the University of Warsaw’s Faculty of Physics … Read more
