Exporting coordinate date using the PCB design software’s own functions is the most common method for exporting coordinate data.Most factories use this method to obtain component coordinate data.Most factories use this method to obtain component coordinate date.Then steps can be roughly divided into three:switching units,setting the coordinate origin,and exporting coordinates.The following describes methods for exporting…
This article clearly identifies humidity-related issues in printed circuit board.It’s a precise article on mitigating the effects of moisture on any type of printed circuit board.From material integration,PCB layout protyping,PCB engineering,assembly,to packing and order delivery,attention should be paid to the effects of moisture in PCB manufacturing to avoid damage and other issues with PCB functionality.Furthermore,let’s…
1.The primary purpose of baking PCBs is to remove moisture and humidity, removing water vapor trapped within the PCB or absorbed from the outside. This is because some PCB materials are prone to forming water molecules. In addition, after being manufactured and stored for a period of time, PCBs may also absorb moisture from the…
As all electronics engineer must konw,PCB design plays a crucial role in design.Taking a power supply as an example ,pcb design directly impacts its EMC performance, output noise ,interference immunity,and even basic functionality .PCB routing in a power supply differs slightly differs slightly from other hardware.How should it be designed? Spacing For high voltage products,row…
PCB(printed circuit board) are key supporting structures for electronic components,connecting them with metal conductors to enable the functionality of various electronic devices.In the early 20th century,traditional PCB manufacturing primarily involved printing each resist.However,with the rapid advancement of semiconductor technology, the demand for PCBs has skyrocketed. Modern PCBs have evolved from single-sided boards to double-sided boards,…
At work, I ensure that assembled PCBs avoid these types of errors. With hundreds of tiny components soldered onto them, PCBs are less robust than you might imagine. If handled improperly, you risk complaints from unhappy system installers whose circuits may not function properly. Should PCB Designers Be Concerned About PCB Handling? Odds are, you’re…
PCB design has become increasingly complex as the complexity of the devices they carry increases.For a long time,circuit designers have worked in isolation,then then transferred the completed schematics to PCB designers.PCB designers the completed their work independently and transferred the Gerber files to the PCB fabricator.These three groups worked in isolation,with lilttle communication. With the…
I once went running with a friend who is an urban planner.As part of her cunning plan to get me running further before I got too tired and bored,she told me about all the various considerations surrounding town zoning and construction.There were also plenty of shenanigans related to local politics that provided a multifaceted distraction….
Introduction PCBs (printed circuit boards) are essential to most modern hardware. However, they are prone to defects during the manufacturing process. These defects can lead to disappointing PCBs and negatively impact product performance and consistent quality. This comprehensive guide analyzes the most significant PCB manufacturing deserts, examines their underlying drivers, and provides potential answers to…
In the manufacturing electronic product,choosing the right pcb is of vital importance. Although cheap PCBS’ save cost,after long-term use,they may bring more risk and hidden danger. As engineers ,we need to balance the pcb quality and cost. 1.Materials and performance Cheap PCBs often use low-quality materials, which can compromise their electrical and mechanical performance. In…
Join the Discussion Group When a PCB engineer lays out a product, it’s not just about layout and routing; the design of the inner power and ground planes is also crucial. When designing inner layers, not only power integrity, signal integrity, and electromagnetic compatibility must be considered, but also design, manufacturing, and performance factors. The…
Recent advances in miniaturization have been a major driver of the electronics industry’s continued growth. As miniaturization continues to drive industry growth, manufacturing electronic products and fabricating PCBs are becoming increasingly challenging. The most challenging aspect of PCB manufacturing is the integration of high-density through-holes (VTHs) and interconnects. VTHs are used to mount electronic components…
Signal isolation allows digital or analog signals to be transmitted without a galvanic connection across the barrier between the transmitter and receiver. This allows the ground or reference voltages outside the transmitter and receiver to differ by as much as several thousand volts and prevents loop currents between different ground potentials that could damage the…
Abstract This paper explores the critical relationship between printed circuit board (PCB) trace width, current carrying capacity, and temperature rise in electronic circuit design. As electronic devices continue to shrink in size while demanding higher performance, understanding these interrelationships becomes increasingly important for reliable PCB design. The article examines the fundamental principles, presents relevant formulas…
