☞ This is the 17006th article published by Metal Processing (mw1950pub). Editor’s Note The production of PCB is very complex. Taking a four-layer printed circuit board as an example, the manufacturing process mainly includes PCB layout, core board production, inner layer PCB layout transfer, core board drilling and inspection, lamination, drilling, copper chemical deposition on … Read more
The construction of component packaging is an important part of PCB design. A small mistake can lead to the entire board failing to work and serious delays in the project.Most CAD tools come with a built-in library for standard component packaging, which can also be obtained from the manufacturer’s design documents and reference design sources. … Read more
1. Common Shortcuts in PCB R+L outputs the wiring length of all networks in the PCB. Ctrl + Left Click completes the auto-routing connection for the line being routed. M + G can change the shape of copper. Press P + T while routing, then Shift + A for direct serpentine routing. T + R … Read more

In the manufacturing of printed circuit boards (PCBs), it is common to encounter solder bridging issues, where unexpected solder connections occur between adjacent pads. This is mainly due to improper pad setup, and if not addressed promptly, it can lead to circuit shorts, affecting normal functionality. So how do you choose pads? Perhaps you can … Read more
The control board is a core component in electronic devices, responsible for crucial functions such as instruction transmission, data processing, and logic control. Through built-in circuit boards and electronic components, it achieves precise control over the operational status of devices. With advancements in technology, the application fields of control boards are increasingly diverse. How should … Read more
1. Spacing Between SMD Components The spacing between SMD components is a crucial issue that engineers must pay attention to during layout. If the spacing is too small, it becomes very difficult to print solder paste and avoid solder bridging.The recommended distances are as follows: Spacing requirements for SMD components: Same type of components:≥0.3mm Different … Read more
