This week's assignment is to understand the electrical behavior of a PCB using tools such as an oscilloscope and a multimeter, as well as to digitally assemble a board using dedicated software
In order to develop the PCB design digitally, it will be necessary to learn how to use the electronics section of Autodesk Fusion
The electronics design section of Autodesk Fusion allows users to create schematics and printed circuit boards (PCBs) within the same environment as mechanical design. It includes tools for placing components, routing connections, and simulating circuit behavior. This integration enables seamless collaboration between electronic and mechanical design, making it ideal for developing compact and functional prototypes.
The project assignment aims to understand all stages of PCB development using the selected software. Additionally, a case will be added to provide portability to the board.
1. As a first step, it is necessary to use the multimeter to properly understand what is happening electrically within our board.q
The Prasek PR-301 multimeter is a digital device designed to measure electrical parameters such as AC/DC voltage (up to 500V), DC current (up to 10A), resistance, continuity, and diodes. It also supports transistor and temperature testing (-40°C to 1000°C). Powered by a 9V battery, it features a 48 x 16 mm LCD display, manual range selection, data hold function, and a low battery indicator. Compact (130 x 74 x 41 mm, 160g) and portable, it’s ideal for electronics technicians. It includes test leads, a battery, and a manual.
2. The continuity test will help us determine if there is a proper transmission of electricity between components.
3. Voltage measurement should be done approximately and progressively to avoid damaging the multimeter.
4. Finally, resistance measurement is done similarly, as it is measured progressively to avoid damaging the equipment
5.To make the Fusion component libraries compatible with the components offered by the lab, the following collection of parts is downloaded to ensure that the pads align correctly.
6.We will start by identifying the parts of the electronics environment in Fusion.
7. The next step is the search, placement, and transformation of our component.
8. A simulation of the circuit is designed in Wokwi, in which a potentiometer progressively lights up an LED while simultaneously controlling the degree of movement of a servo motor.
9. With the components identified, it's time to import them into the schematic in order to create the connections before moving on to the PCB layout.
9. The next step is to convert the schematic into a board design project, which must be arranged and routed in order to be turned into a machining pattern.
10. Finally, the model is exported as an STL to work on it in Rhino, and a case is created to house it in the manufacturing stage
