RoboSolder®: Precision Wire Termination for Pulsed Field Ablation (PFA)

In the rapidly evolving world of medical technology, precision and reliability aren’t optional, they are essential. This is especially true in Pulsed Field Ablation (PFA), where device performance and patient safety depend on the integrity of every connection inside a catheter or ablation system.

Onanon’s RoboSolder®, a patented technology, is redefining wire termination by offering a fully automated, robotically controlled process that ensures unmatched accuracy and consistency.

What is RoboSolder®?

RoboSolder® automates the soldering process by heating pins from the front side while wires are inserted into the solder cup from the back side. This guarantees every joint meets IPC Class III standards.

Designed like a workspace table and equipped with a foot pedal, RoboSolder® activates heating elements for each pin. With customizable templates, it can handle any pin layout—making it especially effective for high-density configurations.

• Terminates wires as fine as 56 AWG

• Programmable to adapt across different pinouts

• Supports connectors as small as a dime, common in PFA devices

The Advantages of Automated Wire Termination

Removing the Human Variable

Traditional wire termination methods often rely on manual processes that introduce variability. RoboSolder® eliminates that risk by making the process 100% automated, ensuring consistency and reliability.

Consistent Quality

Every termination is performed with robotic precision and complies with IPC Class III—the highest industry benchmark. This eliminates cold solder joints and ensures secure, accurate connections.

Increased Speed

RoboSolder® significantly reduces cycle times. Assemblies that once required 40+ minutes of manual labor can now be completed in just minutes—boosting throughput without sacrificing quality.

Reduction of Strain

By automating repetitive, high-precision tasks, RoboSolder® reduces strain on workers, improves workplace safety, and minimizes rework or scrap—lowering costs overall.

Optimized for PFA Devices

Unlike crimping or laser welding, which struggle with ultra-fine wires, RoboSolder® excels at 20–56 AWG wire termination. This makes it the solution of choice for PFA systems, where catheter integrity and reliability are non-negotiable.

Why RoboSolder® is the Solution

As Pulsed Field Ablation (PFA) continues to reshape the future of cardiac care, the demand for high-density interconnects will only grow. Device manufacturers need solutions that meet today’s performance requirements while anticipating tomorrow’s regulatory, scalability, and safety demands.

RoboSolder® delivers:

• Fully automated, IPC Class III–compliant wire terminations down to 56 AWG

• Repeatable and traceable connections for large-scale production

• Improved throughput and reduced manufacturing costs

• Design flexibility for more compact and complex devices

Building Trust in Every Connection

With its patented automation, unmatched precision, and adaptability, RoboSolder® is setting the foundation for the next generation of medical technology.
