  They’re vital for the functionality of a device like a laptop, washing machine, or calculator. The number and type of components can vary significantly based on the device and PCB type . However, the most common types of electrical components infused in a printed circuit board include: Resistors Transistors Inductors Capacitors Transformers Sensors Diodes If even one component stops working, the whole PCB shuts down. Thus, the device it belongs to will shut down as well. Here, we will discuss the crucial PCB components, what they do, and why they’re important. Resistors They’re among the most crucial components in nearly all types of printed circuit boards. They produce and transmit electric currents to cause a voltage that helps dissipate electric power as heat energy. Although resistors have the same purpose, they still come in a wide variety in terms of shape, size, and power. They’re basically based on the resistance value and are easy to identify using color codes. Transisto...

  If you’ve wondered whether a multilayer printed circuit board (PCB) is right for your next project, this guide is for you. Read on to learn more about this popular type of PCB, including where and how they are used, potential cost drivers, advantages and challenges, and much more. What Are Multilayer PCBs? Multilayer PCB s contain three or more copper conductive layers — usually with plated through holes. If a board is constructed with both flexible and rigid materials, it’s known as a  rigid-flex PCB . A rigid-flex circuit board is a 3D interconnect that can be bent and folded into almost any shape. Rigid-flex technology allows designers to replace multiple PCBs with interconnecting wires and/or cables into one single unit, offering improved performance and increased reliability. Multilayer PCB Use Applications Multilayer PCBs  are extremely common and can be found in a variety of applications and industries, including: Computers and laptops Consumer products Telecommu...

  How can you distinguish between single-layer and multilayer PCBs? To identify the PCB type, two basic procedures can be followed as mentioned below: 1. Hold the PCB in a cross-sectional view with a light source; if the inner core is opaque or entirely black, it indicates a multilayer board . If the core is transparent, it is a single or double-sided board. Single-sided boards are easy to identify because they do not have copper inside the holes. 2. A single-layer PCB has only one layer of lines (copper layer), without metallization in the holes, and no plating procedure. In contrast, a double-layer PCB consists of two lines (copper layer), with both metalized and non-metalized holes, along with a plating procedure. Multilayer PCB Laminate Technology Multilayer PCB (Printed Circuit Board) laminate technology is a critical advancement in electronic circuit design, enabling the creation of more complex and compact devices. In a multilayer PCB, multiple layers of conductive copper a...

  In a typical four-layer stack-up, to enhance electromagnetic compatibility (EMI) performance, the signal layers should be closely spaced to the ground planes. The close coupling between the signal trace and ground plane typically decreases plane impedance, common-mode radiation, and crosstalk between traces. As the number of layers increases, the PCB board necessitates thin dielectric, resulting in automatic tight coupling between the layers. These stack-ups are commonly utilized in high-speed electronics to provide enhanced EMI performance and signal integrity. More inner layers will help produce a compact design, lightweight production, durability, and flexibility for a wide range of industries, including consumer electronics, and telecommunications. Several applications, such as smart devices, require four to eight layers, while smartphones can use up to twelve. The Benefits of Multilayer PCBs Even though the design process for multilayer PCBs is complex and requires domain ex...
