• Pinyin (with tone marks): diàn lù bǎn
• Part of Speech: Noun
• HSK Level: N/A (Specialized/Technical)
• Concise Definition: A flat board made of insulating material on which conductive pathways and electronic components are mounted to form a circuit.
• In a Nutshell: 电路板 (diànlùbǎn) is the direct and standard term for the green, blue, or red board you find inside any electronic device. It's the physical foundation that holds and connects all the tiny components like chips and resistors, allowing the device to function. The word itself is a perfect example of Chinese logic: “electricity-path-board”.

• 电 (diàn): Electricity, electric. The character originally depicted lightning (申) under a rain cloud (雨), vividly capturing the concept of electricity from nature.
• 路 (lù): Road, path, way. This character combines a foot (足) and a marker for “each” or “various” (各), suggesting a path that one walks on. In this context, it means the conductive pathways or “traces” for the electricity.
• 板 (bǎn): Board, plank, plate. This character is composed of the radical for tree/wood (木) and a phonetic component (反). It refers to a flat piece of material, originally wood.

When combined, 电路板 (diànlùbǎn) literally translates to an “electricity-path-board”—a remarkably clear and descriptive name for a circuit board.

While a 电路板 is a universal technical component, in the context of modern China, it carries significant weight. It is a tangible symbol of the “Made in China 2025” initiative and the country's transformation from a low-tech manufacturer to a global high-tech powerhouse. In the West, a “PCB” is often seen purely as a piece of engineered hardware. In China, the 电路板 (diànlùbǎn) represents the foundation of the vast electronics manufacturing ecosystem, especially in cities like Shenzhen (深圳), often called the “Silicon Valley of Hardware.” For millions of workers, engineers, and entrepreneurs, the 电路板 is not just a component; it's the basis of their livelihood, a product of their innovation, and a key element in the global supply chain that China dominates. It embodies the speed, scale, and dynamism of China's tech industry.

电路板 is a neutral, technical term used across various contexts, from professional engineering to casual conversation about broken gadgets.

• In Engineering and Manufacturing: It is the standard term used by engineers, factory managers, and supply chain specialists when designing, producing, or sourcing PCBs.
• In Tech Repair: When you take a broken phone or computer to a repair shop, the technician might point to the problem and say the 电路板 is damaged (坏了, huài le).
• In DIY and Hobbyist Circles: Electronics enthusiasts (电子爱好者, diànzǐ àihàozhě) use this term when discussing their projects.
• In General Conversation: Anyone discussing the “guts” of an electronic device will use 电路板. For example, “I opened up the old radio and saw a very simple 电路板 inside.”

• Example 1:
  • 这台电脑的电路板烧坏了。
  • Pinyin: Zhè tái diànnǎo de diànlùbǎn shāo huài le.
  • English: This computer's circuit board is burned out.
  • Analysis: A very common phrase used when diagnosing a problem with an electronic device. “烧坏了 (shāo huài le)” literally means “burned broken” and is the standard way to say something has “fried” or short-circuited.
• Example 2:
  • 我们的工厂每个月生产五十万块电路板。
  • Pinyin: Wǒmen de gōngchǎng měi ge yuè shēngchǎn wǔshí wàn kuài diànlùbǎn.
  • English: Our factory produces 500,000 circuit boards every month.
  • Analysis: This sentence showcases the term in a manufacturing context. The measure word for a flat object like a board is “块 (kuài)”.
• Example 3:
  • 他是一位专门设计电路板的工程师。
  • Pinyin: Tā shì yī wèi zhuānmén shèjì diànlùbǎn de gōngchéngshī.
  • English: He is an engineer who specializes in designing circuit boards.
  • Analysis: This shows the professional application of the term. “专门 (zhuānmén)” means “to specialize in.”
• Example 4:
  • 你看，这个芯片是直接焊接在电路板上的。
  • Pinyin: Nǐ kàn, zhè ge xīnpiàn shì zhíjiē hànjiē zài diànlùbǎn shàng de.
  • English: Look, this chip is soldered directly onto the circuit board.
  • Analysis: This sentence introduces related vocabulary like “芯片 (xīnpiàn)” (chip) and “焊接 (hànjiē)” (to solder).
• Example 5:
  • 深圳是全球最大的电路板采购中心之一。
  • Pinyin: Shēnzhèn shì quánqiú zuì dà de diànlùbǎn cǎigòu zhōngxīn zhī yī.
  • English: Shenzhen is one of the world's largest procurement centers for circuit boards.
  • Analysis: This connects the term to its geographical and economic context in China.

  • Analysis: A modern, environmentally-conscious usage of the term. “废旧 (fèijiù)” means old and discarded.

• 电路板 (diànlùbǎn) vs. 主板 (zhǔbǎn): This is the most common point of confusion for learners.
  • 电路板 (diànlùbǎn) is the general term for any circuit board (PCB). A TV remote, a toy, and a computer all have one or more `电路板`.
  • 主板 (zhǔbǎn) means “motherboard” or “mainboard”. It is the main, central circuit board in a complex device like a computer or a smartphone, to which other components and smaller `电路板` connect.
  • Incorrect: “我电脑的电路板坏了。” (Wǒ diànnǎo de diànlùbǎn huài le.) - “My computer's circuit board is broken.” While not technically wrong, it's imprecise.
  • Correct: “我电脑的主板坏了。” (Wǒ diànnǎo de zhǔbǎn huài le.) - “My computer's motherboard is broken.” This is much more specific and natural.
• Don't Abbreviate: While English speakers casually say “the board,” in Chinese, you should almost always use the full term 电路板 to avoid ambiguity. Simply saying “板 (bǎn)” would just mean “plank” or “board” in a general sense and would not be understood as a circuit board.

• 主板 (zhǔbǎn) - Motherboard. The main, primary `电路板` in a complex system.
• 芯片 (xīnpiàn) - Chip / Integrated Circuit (IC). A key component mounted on a `电路板`.
• 电子元件 (diànzǐ yuánjiàn) - Electronic components. The general term for all parts (resistors, capacitors, chips) found on a `电路板`.
• 硬件 (yìngjiàn) - Hardware. The category of physical equipment that includes `电路板`.
• 集成电路 (jíchéng diànlù) - Integrated Circuit (IC). A more formal and technical term for `芯片`.
• 焊接 (hànjiē) - To solder / weld. The process used to attach components to a `电路板`.
• 短路 (duǎnlù) - Short circuit. A common failure mode for a `电路板`.
• 电源 (diànyuán) - Power supply. The component that provides electricity to the `电路板`.
• 深圳 (Shēnzhèn) - The city in China famous for its massive electronics markets and `电路板` manufacturing.
