What are schematics or circuit board diagrams?

Circuit board diagrams are graphical representations of electrical circuits, including all electrical connections, showcasing the arrangement of all the wires and components. Circuit board diagrams are created with the intention of producing a final circuit design, often to elaborate a PCB’s layout.

There are different kinds of circuit diagrams:


Schematic diagrams

This type of diagram shows all of the components and connections of the circuit, just like a technical map, only that they aren’t necessarily going to be pointing out the final design locations of each component in the physical device, they communicate lots of information by using standardized symbolic representations.

These give a visual representation of the circuit to an electrical engineer or electrician, and tell him exactly which components are needed, and how they must be connected to fulfill their functions, but they do not provide any physical layout of where the wiring should go.

Pictorial circuit diagrams

This type of diagram is a simple representation of the physical mapping of an electrical circuit, showing where fixtures and components are connected to the system. They’re typically intended for a less technical audience.

They often show the physical appearance of the device in a better and more easily understood way than other diagrams, and can contain photos or sketches of the physical components with proper labeling, so anyone can understand what they are depicting.

Wiring diagrams

Wiring diagrams use simplified shapes and lines to represent each component of the circuit, and are often used to assist in the manufacturing of electronic devices, by providing easy-to-read-data about the features and relative positions of the circuit’s parts to every member of the team.

They show how each wire should be located in the device and the relationship between all the physical connections for each component.

How to read circuit diagrams and electrical schematics?

Reading a schematic diagram starts with a simple principle: you need to understand what every symbol means, and how they connect to each other.

Each symbol represents an electronic component (except the ones that connect to the power supply) also the lines between these symbols are a representation of the wires that connect everything.

There are lots of places online where you can see all of the meanings of all the available schematic symbols. To fully understand a diagram you must know each of them, understand what their values mean and how they function. The main components of an electrical diagram are:

  • Batteries: generally acid or alkali-based power supplies.
  • Capacitors: their function is to store and release electrical charge.
  • Resistors: they oppose current and pass the current needed in proportion to the voltage
  • Variable resistors or potentiometers: variable voltage dividers
  • Diodes: they are used to easily conduct electricity in a certain direction
  • Transistors: semiconductors used to amplify and switch electronic signals
  • Inductors: they use magnetism to release electrical charges in storage
  • Integrated circuits: small single-piece sets of electronic circuits
  • Logic gates: semiconductor used to change the state of the output based on the rules of the inputs.
  • Operational amplifiers (Opamps): electronic voltage amplifiers
  • Switches: devices designed to block or reroute current
  • Transformer: they transfer electrical energy between circuits through electromagnetic induction

If you want to gather some experience reading or designing these diagrams after learning the basics, you can find many electronic schematic drawings made by hobbyists all over the web. This will give you a place to start with designing your own electronic circuits, but you will find that it’s much quicker, less stressful and more cost-effective (time is money after all!) to have an experienced team working on your design, who can either design the circuits completely, or add any useful insights and modifications to a diagram you have created before using the diagram to create a prototype.

Benefits of outsourcing your schematic drawings and modifications

Creating drawing schematics or wiring diagrams is a complex task that should ideally be performed by an experienced electronic design team, as it requires a deep understanding of electrical components, their connections and functionality within the circuit. Also, because we’re talking about devices using electricity, it’s also important for safety reasons that they are created in the correct way.

It’s also advisable that both the hardware and firmware design teams work together to develop the diagrams of the electronic product you’re creating, to ensure they are made accurately and without any design flaws after diagramming and before software testing.

In order to save time and money, your electronic design department must avoid bringing design issues into prototyping stages, as otherwise you can end up having to go back to the beginning to start all over again with the design and development of your electronic product.

If you don’t currently have a knowledgeable team of electronic development engineers with experience on PCB hardware, firmware, and their relationship to the electronic components that your product requires, as well as a good deal of experience with schematic drawing, then get in touch with us today! Working with JCAD – Inc. you can rest assured that the design of your electronic product is in the best hands possible.

When your diagrams are made by experienced designers, like our electronics team, you can quickly get an accurate and fully functional circuit diagram, that can be tested and brought in for prototyping and eventual production.

We would love to help you design your schematic plans, and to handle all of the electronic design automation (EDA) so the manufacturing process of your electronic product is easy and cost-effective.
