From Microns to Precision: Cleanrooms Safeguard Connector Quality

In connector production, a dust particle as small as 5 μm can cause a short circuit in a 0.35 mm pitch connector. For precision electronic components, cleanrooms are not just a production standard. They are the foundation of quality and reliability.

Clean Environment, Precise Manufacturing

As connectors become smaller and denser, manufacturing precision increases. Cleanrooms are essential to ensure this precision. Their value can be seen in three areas:

1. Higher Yield Rates

By controlling air cleanliness, cleanrooms reduce dust and particle contamination. This prevents short circuits, poor contact, unstable signals, and mechanical jamming. As a result, the first-pass yield rate improves significantly.

2. Support for Precision Manufacturing

Connector production involves micron-level processes. For example, mold precision is controlled within ±0.002 mm. A human hair is about 60 μm, while our mold tolerance is only 1/30 of that. At such precision, even a single dust particle becomes a “micro mountain,” affecting surface quality, assembly smoothness, and measurement accuracy.

3. Compliance with Industry Standards

Cleanrooms are also key to passing international certifications such as ISO. They ensure that production meets global regulations and customer requirements.

Greenconn’s Clean Manufacturing Strength

With 27 years of experience, Greenconn has developed a comprehensive cleanroom management system. It complies with ISO standards and high-level cleanliness requirements, with full-process protection measures in place:

1.Full-Process Protection

Air shower entry: Operators wear protective suits and pass through air showers for dust removal.

Material purification: Plastics, trays, terminals, and carrier tapes are pre-cleaned with specialized equipment before entering production.

Assembly protection: Automated lines include ionized air stations to ensure assembled parts remain dust-free.

Clean packaging: After robotic dust removal, components are vacuum-sealed in PE bags to prevent secondary contamination.

2.One-Stop Cleanliness Solutions

Advanced equipment: High-pressure spray, ultrasonic cleaning, and hot air drying ensure automated cleaning and drying.

Quality system: From particle extraction and analysis to lab testing and staff training, a complete cleanliness control and process optimization framework is in place.

“Small dust, big risks.” As connectors evolve toward higher density and smaller sizes, cleanrooms are critical not only for yield, but also for precision manufacturing and competitiveness. Greenconn will continue to apply strict cleanliness standards and advanced precision capabilities to deliver reliable, high-quality connector solutions for global customers.
