Printed Circuit Board: Exploring the Essentials of PCB Design and Artwork

printed circuit board pcb design

Before starting the design of the board with the CAD tools, it is necessary to ensure that the library part designs are completed. For the schematic, this means creating logic symbols for the parts that will be implemented; resistors, capacitors, inductors, connectors, and integrated circuits (ICs). A metal-core PCB is something of an offshoot of rigid board designs, with an increased ability to dissipate heat throughout the board to protect sensitive circuitry. This style can be an option for high-current designs to prevent thermal wear and failure. One distinguishing characteristic of PCBs is their class–either 1, 2, or 3. The class of PCB indicates its overall reliability and quality of design.

Printed circuit boards are not used in applications where the electrical components require a high degree of mobility, flexibility or in some applications where the design is highly customized. The decision to use a PCB or an alternative wiring method will depend on the specific requirements of the application, including factors such as cost, reliability, space constraints, and frequency requirements. After you create schematics and verify electrical functionality with simulation tools, you need to define your layer stack, which will show the arrangement of signal layers, each power plane, and each ground plane. These design rules and constraints can be defined around specific industry standards that govern manufacturability and functionality. This helps ensure that you do not make any errors while creating your PCB layout.

PCB design is like designing a city

Once the conceptual design is finalized, the next step is schematic design, where the electrical connections and components are defined using a schematic capture tool. The schematic serves as a blueprint for the PCB layout and provides a clear representation of the electrical functionality of the circuit. Printed Circuit Board (PCB) design involves the creation of a layout that defines the electrical connections and mechanical structure of an electronic device.

Organic flexible electronics with closed-loop recycling for sustainable wearable technology

Many times, the first building block of a simple PCB is just a piece of FR-4 sheeting laminated to a single side. The tracks, pads and other features are then etched out of the copper that has been laminated to the PCB material. In addition to impedance matching, designers must also use proper termination techniques to minimize signal reflections. Termination involves placing a resistive load at the end of a signal path to absorb any reflected energy and prevent it from propagating back toward the source. A well-designed schematic should be clear, accurate, and easy to understand, even for someone unfamiliar with the specific project.

According to MNI, compiler and publisher of the industrial data that powers IndustrySelect, there are currently 918 printed circuit board manufacturers in the United States. The industry accounts for 54,080 jobs as of July 2022, an increase of 3% over the past twelve months. The industry has reported total sales of $37.5 billion in 2022, up from $36.4 billion in 2021.

Use PCB Tools for High-Quality Design

The CAD tools will have design rules built into them that prevent the traces of one net from touching another net as well as governing many other widths and spaces needed for a complete design. Once the routing is complete, the design tools are used again to create manufacturing drawings and the output files that the manufacturer will use to build the board. A recent United Nations report found that the world generated 137 billion pounds of electronic waste in 2022, an 82% increase from 2010. While many things impede a sustainable afterlife for electronics, one is that we don't have systems at scale to recycle the printed circuit boards (PCBs) found in nearly all electronic devices.

The next layer after the substrate is a layer of copper foil, which is attached with an adhesive and then heat-fixed to the substrate.

By conducting heat away from the component and into the surrounding PCB material, thermal vias help to spread the heat more evenly across the board and prevent localized hot spots. Thermal management is a critical aspect of PCB design that ensures the reliable operation and longevity of electronic components. Proper thermal management involves the efficient dissipation of heat generated by components, preventing overheating and potential damage to the PCB and its components. Effective noise reduction strategies often involve a combination of these techniques, tailored to the specific requirements of the application. For example, in a mixed-signal design, designers may use a combination of shielding, differential signaling, and filtering to reduce crosstalk between analog and digital signals.

As one of the printed circuit board manufacturers focused on solving complicated supply chain issues, this facility works with full system assemblies and complex electronics. A printed circuit board (PCB) is a board made for connecting electronic components together. This article has provided an in-depth overview of different types of PCBs and their applications in the electronics industry.

Learning how to design a PCB layout can be separated into two major tasks. Before you create a layout, you need to create a schematic that includes the components your system needs and shows connections between them. Once your schematic is created and successfully verified, you can transfer your design to a PCB layout, which defines the physical architecture of your board. This may seem simple enough, but each task requires several interdependent steps. Moreover, there are constraints and guidelines that must be followed to ensure your design can actually be manufactured.

PCB fabrication and manufacturing starts with the right design, and far too many PCBs are the result of cheap engineering or designers who aren’t equipped with specialized knowledge and experience. Jumping into PCB board design for the first time or picking up a new design software platform can be daunting. Luckily, Altium provides you with the resources and PCB layout tutorials you need to be successful. The AltiumLive forum, webinars provided by industry experts, and Altium’s thorough knowledge base will show you several design guidelines for various applications.

To properly power your ICs, we recommend using common rails for each supply. Also, be sure to use solid and wide traces to let that power easily flow through to your energy-hungry ICs, and avoid daisy-chaining power lines between parts to prevent any voltage drop issues. ICs with a ton of pins, or any IC for that matter, needs to be given plenty of space between other ICs on your board for easy routing. Many beginner designers will make the mistake of packing their ICs too close together, leaving little to no room to route all the required pins.
