Why is PCB Handling Challenging for Automation?

In electronic manufacturing, PCB (Printed Circuit Board) handling has always been a challenging process.PCBs typically have the following characteristics:

• Dense electronic components and sensitive circuits on the surface;
• Lightweight and thin structures that are prone to deformation;
• Strict requirements for positioning accuracy;
• High demands for ESD (Electrostatic Discharge) protection.

Traditional pneumatic grippers or rigid fixtures usually rely on edge clamping, directly contacting the PCB edges during handling.However, in real production environments, this method may cause:

• Edge deformation or damage caused by excessive gripping force;
• Unstable positioning during high-speed movement;
• Falling risks due to insufficient contact stability;
• Potential ESD concerns from rigid metal contact.

For high-value and precision PCBs, achieving safe, stable, and damage-free handling is a key challenge in automation.

Soft Gripper + Customized Fixture: A New Approach to PCB Handling

To address the structural characteristics of PCBs, we developed a solution combining a soft robotic gripper with a customized internal expansion fixture.Instead of gripping from the outside, the system uses the small circular holes already designed on the PCB as positioning points.The soft gripper enters the holes and expands gently, creating an internal supporting force to securely hold the PCB.Compared with traditional edge-clamping methods, this approach provides significant advantages:

Safer PCB Handling: No ESD Risk, No Falling, No Damage

For the most critical concerns in electronics manufacturing, this solution provides:

✅ Reduced ESD Risk

The flexible gripping method avoids direct contact between rigid metal fixtures and sensitive PCB surfaces, helping improve electrostatic protection.

✅ Stable Handling Without Dropping

The internal expansion structure provides reliable support, keeping the PCB stable even during robot acceleration, movement, and rotation.

✅ Lowest Damage Possibility

The combination of flexible contact and precise positioning greatly reduces the possibility of PCB damage caused by gripping.

As electronic products continue to become smaller, more integrated, and more precise, traditional rigid fixtures are becoming increasingly difficult to meet modern manufacturing requirements.The combination of:Soft Gripping + Internal Positioning + Precise Controlprovides a safer and more efficient solution for PCB automated handling.For manufacturers looking to reduce product loss, improve production stability, and upgrade automation processes, this innovative gripping method offers a new choice for precision PCB transfer.
