What Are the Applications of Industrial Robots in the PCB Industry?

As robot performance improves and prices decline, the traditional production model of "automated equipment + manual operation" is gradually being replaced by "automated equipment + industrial robot operation" – a trend that will shape the transformation and development of the PCB industry.

The PCB industry is technology‑intensive and capital‑intensive, yet it remains labour‑intensive as well. A large amount of automated equipment still requires manual handling and assembly‑line operations; a medium‑sized PCB manufacturer may employ several thousand workers. With industrial transfer and upgrading, the implementation of the new Labour Contract Law, rising urban living costs driven by economic restructuring, and the increasing difficulty of managing younger workers along with high turnover rates, PCB manufacturers are facing growing challenges from labour shortages and rising labour costs. These issues in turn affect production schedules, product quality, and profitability. At the same time, as robot performance improves and prices drop, the shift from "automated equipment + manual operation" to "automated equipment + industrial robot operation" is becoming an inevitable trend in the industry's transformation.

The most notable characteristics of industrial robots can be summarised in three points:

1. Programmability. The next stage of production automation is flexible automation. Industrial robots can be reprogrammed as needed to adapt to changing work tasks and environmental requirements.

2. Human‑like features. In terms of mechanical structure, industrial robots have components resembling human walking, waist rotation, upper arm, forearm, wrist, and gripper; they are also equipped with computer control systems.

3. Versatility. Apart from specially designed dedicated robots, general‑purpose industrial robots offer good adaptability for performing different tasks.

Advantages of replacing manual labour with industrial robots in the PCB industry:

Like the automotive and other manufacturing sectors, the use of industrial robots in the PCB industry brings numerous benefits to enterprises.

1. Reduced labour, faster work cycles, and improved efficiency. Robots can perform repetitive operations at high speeds, achieving much faster work cycles than humans, which significantly boosts productivity while lowering labour and management costs.

2. Enhanced operational accuracy and product quality. With programming and vision systems, robots achieve precise positioning and repeatable accuracy, effectively improving product quality.

3. Elimination of potential health and safety risks to workers from the working environment, reducing investment in environmental safety measures.

4. Reduction in efficiency and quality degradation, as well as accident rates, caused by worker fatigue and distraction in repetitive, monotonous processes.

5. Optimised workflow and reduced floor space requirements.

6. Effective reduction in material consumption rates.

7. Ability to operate 24/7 and in lights‑out environments.

8. Enhanced manufacturing flexibility. As the PCB industry faces increasing numbers of small‑batch orders, using industrial robots greatly improves production flexibility and enables rapid order fulfilment.

9. Improved brand image and reputation. The adoption of industrial robots elevates a PCB manufacturer’s level of automation, driving improvements in product quality, production efficiency, cost control, and responsiveness, thereby strengthening overall competitiveness in the industry.

Future trends in the application of industrial robots in the PCB industry:

1. From single‑station or single‑line applications to multi‑line applications. It is challenging for existing PCB companies to fully introduce robots for automated production in one go, as this requires substantial capital investment for retrofitting. However, they can implement gradual upgrades on suitable single stations and lines, and after achieving visible results, progressively expand the scope of application.

2. From standalone robot applications to integration with other intelligent equipment such as AGVs. Currently, material transfer between production lines in most factories is done manually. A step‑by‑step approach can be adopted, combining robots and AGVs to achieve orderly material flow.

3. Existing factories will mainly adopt partial applications, while new plant construction will incorporate overall planning that directly integrates robots and AGVs.

4. Through the integration of industrial robots with the Internet of Things, the manufacturing process will become more intelligent and flexible.
