Printed circuit board - Wikipedia
A printed circuit board (PCB), also called printed wiring board (PWB), is a medium used to connect or "wire" components to one another in a circuit.
这些“黑话”只有PCB设计制造内行人才懂！附PCB术语及英文对照
2021年11月3日 · Test Coupon，是用来以 TDR (Time Domain Reflectometer 时域反射计) 来测量所生产的 PCB 的特性阻抗是否满足设计的要求，一般要控制的阻抗有单端线和差分对两种情况，所以 test coupon 上的走线线宽和线距 (有差分对时)要与所要控制的线一样，最重要的是测量时接地点的位置。 为了减少接地引线 (ground lead) 的电感值，TDR 探棒 (probe)接地的地方通常非常接近量信号的地方 (probe tip),所以 test coupon 上量测信号的点跟接地点的距离和方式要符 …

就是指在PCB鋪銅 (Copper Pour) 一般PCB在電路設計時經常需要鋪設大面積的銅箔來當作電源(Vcc、Vdd或Vss)與接地(GND，Ground)之用。 F.Cu及B.Cu都可以鋪. Thermal relief Pad:
印制电路板 - 维基百科，自由的百科全书
印刷电路板，又称 印制电路板， 印刷线路板，常用英文缩写 PCB （Printed circuit board）或 PWB （Printed wire board），是 电子元件 的支撑体，在這其中有金屬 導體 作为連接电子元器件的線路。 傳統的電路板，採用印刷 蝕刻 阻劑的工法，做出電路的線路及圖面，因此被稱為印刷電路板或印刷線路板。 由於電子產品不斷微小化跟精細化，目前大多數的電路板都是採用貼附蝕刻阻劑（壓膜或塗佈），經過曝光顯影後，再以蝕刻做出電路板。 pcb [1] （页面存档备份，存于 …
The Ultimate Guide to Circuit Board Patterns!-FS PCBA
Circuit board patterns play a crucial role in electronic design and PCB layout. They define the interconnections, signal routing, and power distribution within the board, ensuring reliable signal transmission, minimizing interference, and optimizing system performance.
PCB Design: How to Create a Printed Circuit Board From Scratch
2020年6月24日 · To design a Printed Circuit Board (PCB), you need to draw holes, pads, and wires for your circuit. When you’re done drawing the board, you can either send the design to a manufacturer that will make it for you (it’s actually pretty cheap) – …
PCB Pattern: Pattern vs. Footprint - PCB and Assembly - MADPCB
In PCB manufacturing, we address different patterns into land pattern, circuit pattern, solder mask pattern and etc. PCB patterns formation is starting to shift away from the mask exposure technique used in the past toward direct exposure which
The Ultimate Guide to Circuit Board Patterns - Highleap Electronic
The PCB pattern is responsible for defining how different components in the circuit are interconnected. It acts as a guide for the electrical connections, ensuring that each component communicates effectively with the others. Without a well-designed PCB pattern, the circuit’s functionality could be compromised.
The IPC-7351 Standard in PCB Footprints and Land Patterns
2020年9月8日 · Here’s what you need to know about designing a PCB land pattern to comply with the IPC-7351 standard, and how your design tools can help. What’s in the IPC-7351 Standard? The IPC-7351 standard specifies some important SOIC footprint dimensions while creating the PCB land pattern; these are the pad width (X), pad spacing (G), and end-to-end ...
Unlock the Secrets of Circuit Board Patterns: A Comprehensive …
PCB patterns describe the arrangement of conductive routes or electronic elements on PCBs. You can construct PCBs from insulating materials like plastic or fiberglass, with etched conductive pathways that serve to join the electrical components. This article covers various PCB patterns, each having its distinctive layout and design.
