When it comes to circuit boards, precision is non-negotiable. It’s important to understand the different types of circuit board components because they act as essential building blocks for PCBs. There are a variety of crucial parts on a PCB, including electromechanical components, like switches, relays or connectors, as well as displays and sensors. Passive and active components are critical to the proper functioning of PCBs. Let’s explore the differences between these types of circuit board components and how Siemens Manufacturing stands out in providing exceptional solutions.

Understanding Circuit Board Components

Circuit board components perform a variety of key functions, including controlling the flow of electricity, powering the circuit, or directing the current. They work to connect different aspects of the printed circuit board, and passive and active components are especially impactful.

The distinction between passive and active components matters for both design and performance. For instance, passive components don’t require a power source to operate, and cannot amplify or generate energy. They support stable and reliable operation, and can be used for noise filtering or signal tuning. Examples of passive components include:

  • Resistors control current flow. Failures with resistors can lead to incorrect voltage levels and excessive heat from overloading, which can cause fire or burning.
  • Capacitors store and release energy. Defects here can cause short circuits, fires, or explosions.
  • Inductors manage changes in current, but failures can result in efficiency loss.
  • Transformers regulate voltage conversion in certain applications, but if improperly configured, failures can lead to insulation breakdown and shorts.

On the other hand, active components require external power to function and they are able to amplify and modulate the signal. They enable signal processing, amplification, and more. Examples of active components include:

  • Transistors switch or amplify signals. Failures can lead to loss of amplification or can even destroy the device.
  • Diodes control current direction. Poor performing diodes can lead to short circuits, open circuits, or failure to regulate voltage properly.
  • Integrated circuits enable complex functions in a compact form, and failures can cause intermittent or total system dysfunction.

Circuit board components are the core building blocks that allow electronic devices to properly function. Without passive or active components, you can expect electronic defects, and without an expert partner like Siemens Manufacturing, you can expect total project failure.
