Precision Electronics Manufacturing: Dual Air System Ensures Clean and Efficient Compressed Air

Driven by the 5G boom, demand for multilayer circuit boards has surged. In micron-level processes of precision electronic component manufacturing, stable and clean compressed air is critical—air quality directly affects yield and productivity.

A leading domestic materials company, specializing in copper-clad laminates and prepregs, faced escalating production and technical upgrade pressures. Their existing single micro-oil compressor system could no longer meet the higher standards of air quality, operational stability, and cost efficiency, creating a bottleneck for capacity expansion.

Tailored Dual-Station, Dual-Pipeline Solution

Linghein addressed three core requirements:

1. Dual air quality needs – Oil-free air for critical processes, and high-efficiency, energy-saving compressed air for standard processes.

2. 24-hour stable supply – Tight pressure stability to prevent equipment deviations and data errors.

3. Cost reduction and efficiency – Overcoming high energy consumption and maintenance challenges of conventional compressors.

The solution integrates two independent systems running in parallel to minimize cross-contamination and balance clean air with operational efficiency.

System Deployment & Configuration

· Oil-Free Clean Air System (critical processes): LSW PM series oil-free compressors with sterile filtration deliver ISO 8573-1 Class 0 air, eliminating oil risk for sensitive components like chip packaging.

· High-Efficiency Micro-Oil System (standard processes): Three custom permanent-magnet VSD oil-lubricated compressors dynamically adapt to variable loads, maximizing energy efficiency while ensuring sufficient air quality for SMT, injection molding, and other general processes.

Since commissioning in early 2026, the dual-station, dual-pipeline system has operated reliably, delivering both clean and high-efficiency compressed air. By providing a systemic rather than piecemeal upgrade, Linghein effectively resolved the traditional trade-off between cleanliness and efficiency, supporting capacity expansion, reducing operational cost, and setting a replicable benchmark for precision electronics manufacturing.
