3. 多功能集成

   • 將研磨、清洗、檢測等功能整合至單一設(shè)備，縮短生產(chǎn)周期。

   • 支持柔性制造，快速切換不同規(guī)格PCB板的研磨程序。

   
   

典型應(yīng)用案例

1、 Core functions and application scenarios

surface treatment

Removing oxide layers/stains: The grinder can remove oxide layers, flux residues, or oil stains from the surface of PCB boards, providing a clean substrate for subsequent soldering, SMT, or coating processes.

Flattening treatment: By grinding to eliminate small bumps and depressions on the surface of the PCB board, the precision of component mounting is ensured, especially suitable for high-density interconnect (HDI) boards or flexible circuit boards (FPC).

Roughness adjustment: Some processes (such as tin spraying and gold deposition) require specific surface roughness, and the grinding machine can accurately control the roughness parameters.

edging

Deburring: After cutting, there may be residual burrs on the edges of the PCB board, which can be quickly removed by a grinding machine to avoid burrs scratching components or causing short circuits.

Chamfering/Rounding: Chamfering or rounding the edges of PCB boards to improve assembly safety and reduce stress concentration.

Special process support

Back drilling post-processing: In high-speed signal PCBs, the back drilling process may leave small protrusions, which can be smoothed by grinding machines.

Buried/blind hole opening: The grinding machine can precisely control the opening size to ensure the electrical performance of buried or blind holes.

2、 Equipment type and working principle

Classified by degree of automation

Semi automatic grinding machine: combining mechanical transmission and manual intervention, suitable for medium to large-scale production.

Fully automatic grinding machine: integrating processes such as loading and unloading, grinding, and cleaning, supporting large-scale continuous production with high efficiency but high cost.

Operation process and precautions

Standard Operation Procedure

Loading: Fix the PCB board onto the suction cup or fixture.

Parameter settings: Adjust grinding pressure, speed, etc. according to the type and thickness of the board.

Grinding treatment: Start the equipment, monitor the grinding process, and avoid excessive grinding.

Cleaning and testing: Clean the PCB board after grinding and check the surface quality (such as flatness and roughness).

Cutting: Move qualified products to the next process, rework or scrap unqualified products.

Safety and Maintenance

Protective measures: Wear goggles and dust masks during operation to avoid inhaling dust.

Equipment maintenance: Regularly replace grinding consumables and clean the dust removal system to ensure equipment accuracy.

Static protection: For sensitive PCB boards, anti-static suction cups or grounding measures should be used.

Market Trends and Development Directions

Intelligent upgrade

Integrate AI visual inspection, adjust grinding parameters in real-time, and improve yield.

Realize remote monitoring and predictive maintenance through the Internet of Things (IoT).

Environmental Protection Trend

Develop low dust and low-noise grinding processes to reduce environmental pollution.

Using water-based grinding fluid instead of oil-based media to reduce volatile organic compound (VOC) emissions.

Multi-functional integration

Integrating functions such as grinding, cleaning, and testing into a single device to shorten the production cycle.

Support flexible manufacturing and quickly switch between grinding programs for different specifications of PCB boards.

Typical application cases

5G communication PCB: High frequency materials (such as PTFE) require ultra precision grinding to ensure signal integrity.

Automotive electronic PCB: Remove welding residues through grinding, improve corrosion resistance, and meet automotive grade standards.

Medical equipment PCB: Adopting dust-free grinding technology to avoid cross contamination and meet medical certification requirements.
