PCBA electronic engineer notice 10 kinds of free easy to use circuit design software!

Circuit simulation:

Part Sim

Part Sim is a browser-based circuit simulator that allows users to experiment with circuits.

The simulator has a simple layout to ensure ease of use, while providing a full SPICE simulation engine, a Web-based schematics capture tool, and a graphic oscilloscope to monitor the analog/digital signal levels of the circuit.

The tool also contains a Digi-Key BOM (bill of Materials) that allows users to assign part numbers to design components and then find distributors.

Easy EDA

Easy EDA aims to "help designers turn ideas into manufacturing prototypes faster by providing comprehensive data and collaboration tools for electronic design". Easy EDA provides free online circuit simulation, PCB design and electronic circuit design functions.

One can access a large library of schematic components, PCB packaging and packaging, spice simulations, models, and subcircuits to save design time. You can also invite others to collaborate on projects and easily share designs with your team. The standard version is free to use and offers unlimited public projects and 2 private projects.

PCB circuit board

Autodesk Circuits

Autodesk Circuits is a set of tools for electronic design and experimentation.

Beginners can start simple experiments with Electronics Lab or Circuit Scribe, while more experienced users can jump right into PCB design.

The software offers a number of free introductory tutorials and project tutorials that can be learned through the Electronics Lab.

PCB design:

DesignSpark PCB

DesignSpark PCB describes itself as "the world's easiest to use electronic design software, designed specifically for rapid prototyping and to turn your circuit ideas into testable circuit boards faster".

This software has no restrictions on schematic size, so users have no restrictions when creating PCB designs. Users can also import and export files in any format they need, and can create BOM (Bill of Materials) in the desired format.

While the tool is completely free, it's important to note that users must sign up on its website to unlock the program, and they must confirm which ads are displayed before they can start working.

KiCad EDA

KiCad is a cross-platform open source electronic design automation suite. The kit consists of three different tools: Eeschema (schematic capture), Pcb NEW (PCB layout), and 3D Viewer (viewing board designs in 3D).

The 3D Viewer is a unique tool that can rotate and shift your board to see details you can't see in 2D.

PCBWeb

PCBWeb is a full-featured free electronic design tool that supports both schematics and PCB layouts. For electronics engineers who want to simplify hardware design, PCBWeb is an ideal tool for designing and manufacturing electronic hardware.

Users can design multi-page schematics with PCBWeb's fast, easy-to-use writing tools; PCBWeb also supports copper cladding and DRC checking capabilities, allowing users to lay out multiple layers. The resource also integrates Digi-Key Parts catalog and BOM Manager.

CAD modeling

FreeCAD

FreeCAD is a multi-platform open source parametric 3D modeling tool designed to help users bring design projects to life. This is a versatile tool for all levels of users. FreeCAD is available to beginners, educators, or experienced CAD users who want to get involved in 3D printing.

Programmers can also use Python to "extend FreeCAD's functionality, automate it with scripts, build their own modules, or even embed FreeCAD into their own applications."

QCAD

QCAD is a free open source 2D CAD application. QCAD enables users to create a wide variety of technical drawings, such as architectural plans, interiors, machine parts, schematics, and diagrams.

The functions of this program are listed as follows: layers, blocks (grouping), 35 CAD fonts, more than 40 construction tools, more than 20 modification tools, and so on. Many users have praised QCAD for its easy to use interface and versatility.

ImplicitCAD

"The ImplicitCAD project is committed to harnessing the power of mathematics and computer science to address the design folly of the 3D printing revolution," the ImplicitCAD website says. ImplicitCAD is an open source programmatic CAD tool. This means that ImplicitCAD uses a programming language that can be compiled into 3D objects.

The advantages of programmed CAD include: object reusability and abstractness; Automation of repetitive tasks; Common tools for parametric design and software development, such as version control.

OpenSCAD

OpenSCAD is a free software that can create solid 3D CAD models. It allows designers to create accurate 3D models and parametric designs that can be easily adjusted by changing parameters. These documents are ASCII plain text scripts. As such, OpenSCAD is more of a solid modeling tool for programmers and is often considered an entry-level CAD tool for designing open source hardware, such as scientific and educational science tools.

Circuit design engineering software and online resources tend to be expensive, but can be very beneficial for professionals, students, and hobbyists. These resources are often necessary when users are working on a project or just engineering validation, but the associated costs are prohibitive for many.

Just upload Gerber files, BOM files and design files, and the KINGFORD team will provide a complete quotation within 24h.
