Custom Circuit Boards
Electronic circuit boards are designed according to the specific needs of each project. From simple sensors to complex motor control systems, every PCB is custom-tailored to ensure devices operate efficiently and safely.
For example, if a customer wants to integrate a motor into a device, the PCB is equipped with the appropriate DC or stepper motor drivers. The choice of driver depends on the motor’s size and requirements: TMC series, DRV series, or similar drivers may be used. A small stepper motor can work with a compact driver, while high-torque motors require more powerful drivers.
PCBs also include various input and output elements. If environmental data needs to be captured, sensor inputs are integrated. In a labeling machine, for instance, there might be two sensors and an encoder input to precisely monitor motor movement and paper position.
Outputs vary as well: simple LED or relay outputs control basic on/off functions, while MOSFET outputs manage higher loads safely. This allows motors, heaters, or other devices to be reliably controlled.
Electrical safety and stability are also key considerations in PCB design. Basic components such as resistors, capacitors, and diodes support the orderly and safe operation of the circuitry. As a result, motors and sensors run smoothly, and the PCB achieves a long operational lifespan.
Each custom PCB design is unique. Some projects require only a few sensors and motor drivers, while others involve numerous inputs and outputs, relays, and high-power motor controllers. This flexibility enables project-specific solutions ranging from industrial machinery to consumer electronics.
In summary, electronic PCBs are more than a collection of components: they serve as the central, secure, and optimized control unit for the entire system. Proper planning, component selection, and layout directly influence a device’s success.
Example: PCB for a Labeling Machine
Consider designing the PCB for a labeling machine. This board must handle motor control, sensor data acquisition, and overall system management.
Motor Drivers:
The machine’s stepper motor is high-powered, requiring a larger driver on the PCB. This ensures precise control and high torque.
Sensors:
The sensors operate at 24 V, monitoring paper position and correct label placement.
Voltage Converters:
The motor runs on 48 V, while other components require different voltages. The PCB includes converters for:
- 48 V → 24 V for sensors
- 48 V → 12 V for MOSFET drivers
- 48 V → 5 V for relays
- 48 V → 3.3 V for the microcontroller
This single PCB handles the entire power supply and control, replacing previously separate power supplies and drivers, saving both space and cost.
Inputs and Outputs:
The board has two sensor inputs and one encoder input to track motor movement and label positioning. MOSFET outputs control motors and other loads, while relays manage simple on/off functions.
Conclusion
This example illustrates the critical and customizable nature of electronic PCBs. In custom designs, motors, sensors, relays, and MOSFETs must be properly selected and powered with the correct voltages. A well-thought-out PCB design ensures not only a functioning device but also cost and space savings.
Testing and prototyping are essential to guarantee proper operation of each component and prevent errors. A flexible PCB that is easy to maintain and expand improves long-term performance and customer satisfaction. Optimized layouts reduce electromagnetic interference and enhance overall energy efficiency. Safety mechanisms and protective circuits increase operational reliability and extend device lifespan.
Well-designed PCBs provide both technical and economic value, forming the foundation for reliable, durable, and scalable electronic solutions.
