At Niceone, we understand the importance of incorporating efficient and reliable solutions in the design and manufacturing of front panel Human-Machine Interfaces (HMIs) for rigid printed circuit boards (PCBs). The process of adding cables to a rigid PCB front panel HMI requires careful consideration to ensure optimal functionality, durability, and ease of use. In this article, we will explore three effective options for adding a cable to a rigid PCB front panel HMI, providing you with valuable insights and practical guidance to meet your specific requirements.

Option 1: Direct Cable Connection

The first option involves a direct cable connection to the rigid PCB front panel HMI. This method offers a straightforward and reliable solution for integrating the cable into the HMI design. By soldering the cable directly to the PCB, a strong electrical and mechanical connection is established. This approach minimizes the risk of signal loss or interference, ensuring optimal performance.

To execute a direct cable connection, follow these steps:

  1. Identify the suitable location on the rigid PCB front panel HMI to mount the cable connector.
  2. Carefully align the cable connector with the designated location and secure it in place.
  3. Solder the individual wires of the cable to their corresponding pads on the PCB, ensuring proper insulation and connection integrity.
  4. Test the connectivity and verify the functionality of the cable and HMI.

Option 2: Cable Harness Assembly

For more complex setups or applications requiring multiple cables, a cable harness assembly can be an ideal solution. This approach allows for efficient cable management, reduces clutter, and simplifies maintenance and troubleshooting processes. A cable harness assembly involves grouping multiple cables together into a single assembly and connecting them to the rigid PCB front panel HMI.

To create a cable harness assembly, follow these steps:

  1. Determine the number and types of cables required for your specific application.
  2. Cut the cables to the appropriate lengths, ensuring adequate slack for flexibility.
  3. Group the cables together and secure them using cable ties or clamps at regular intervals.
  4. Identify the corresponding connection points on the rigid PCB front panel HMI.
  5. Connect each cable to its designated point, ensuring proper alignment and secure fastening.
  6. Perform thorough testing to ensure proper functionality and signal integrity.

Option 3: Cable Interface Module

In cases where frequent cable connection/disconnection is necessary, a cable interface module can offer enhanced convenience and flexibility. This option provides a modular solution that allows for easy attachment and detachment of cables without affecting the integrity of the rigid PCB front panel HMI.

To implement a cable interface module, follow these steps:

  1. Select a suitable cable interface module compatible with your rigid PCB front panel HMI.
  2. Mount the module onto the designated location on the front panel, ensuring proper alignment.
  3. Connect the desired cables to the module, following the manufacturer’s instructions for proper installation.
  4. Verify the connectivity and functionality of the cables and HMI.
  5. Test the module’s durability and reliability by performing repeated cable connections and disconnections.


When it comes to adding a cable to a rigid PCB front panel HMI, there are multiple options available, each with its own advantages and considerations. Whether you opt for a direct cable connection, a cable harness assembly, or a cable interface module, it is crucial to carefully evaluate your specific requirements and choose the method that best aligns with your design objectives.
