What about the unqualified items related to component placement?

与件放置相关的不合格项怎么办？

Each element is mathematically coupled to its neighbours.

【couple】每个件与相邻的件精确地接合。

As electric vehicles (EVs) traverse these roads, they connect with these elements, allowing for the continuous transfer of electrical energy from the road to the vehicle's battery.

当电动汽车 (EV) 穿过这些道路时，它们会与这些件接，从而将电能从道路持续传输到车辆的电池。

By using PCBs and ICs together, one could achieve exactly the same functional circuit as that made from discrete components, but with far fewer individual components and tangled wires.

通过将 PCB 和 IC 一起使用，可以实现与分立件相同的功能电路，但单个件和缠绕的电线要少得多。

19. Question: What is the difference between through - hole and surface - mount components in terms of size? Answer: Generally, surface - mount components are smaller in size compared to through - hole components.

19. 问题： 通孔和表面贴装件在尺寸方面有什么区别？答案：通常，与通孔件相比，表面贴装件的尺寸更小。

79. Question: In PCBA, what is the function of a component's footprint on the PCB? Answer: It is the physical layout of the pads and markings on the PCB that correspond to the component, ensuring proper fit and connection.

79. 问题：在 PCBA 中，件在 PCB 上的封装有什么作用？答：PCB 上焊盘和标记的物理布局与件相对应，确保正确配合和接。
