How to Choose a Conformal Coating Valve? - Leiko Technology Provides Professional Guidance

In fields such as electronics manufacturing, automotive electronics, and aerospace, conformal coating (moisture-proof, salt-spray-proof, and corrosion-proof) technology is crucial for the long-term reliability of products. As a core component of conformal coating spraying, the performance of the coating valve directly affects the coating effect and production efficiency. How to choose the right coating valve? Shenzhen Leiko Technology Co., Ltd., with years of experience in fluid control, analyzes the key selection points for you.

I. Main Types of Conformal Coating Valves Main Types of Conformal Coating Valves

1. Dispensing Valve (Precise Control)

Applicable Scenarios : Suitable for high-precision, small-area coating, such as local protection of PCB boards.

Advantages : Precise control of glue dispensing, avoiding waste, suitable for complex circuit board coating.

Recommended Model : Leiko piezoelectric jet valve (fast response, no dripping).

2. Spray Valve (Large Area Coverage)

Applicable Scenarios : Suitable for whole-board spraying or large-area protection, such as automotive electronic modules.

Advantages : Uniform atomization, high coverage efficiency, suitable for mass production.

Recommended Model : Leiko automatic spray valve (adjustable atomization particle size, adaptable to different viscosity conformal coatings).

3. Spray Atomization Valve (Ultra-thin Uniform Coating)

Applicable Scenarios : Scenarios with strict requirements on coating thickness, such as military and medical electronics.

Advantages : Non-contact spraying, uniform coating, avoiding bubbles and accumulation.

Recommended Model : Leiko spray valve coating system (high precision, low loss).

II. Key Factors in Selection Main Types of Conformal Coating Valves Key Factors in Selection

1. Viscosity of Conformal Coating

Different viscosities of conformal coatings (such as low-viscosity acrylic esters and high-viscosity polyurethanes) require matching different valve bodies. Leiko coating valves support multiple viscosity adjustments to ensure stable glue dispensing.

2. Coating Precision Requirements

High-density electronic components require high-precision dispensing valves (such as piezoelectric valves).

Spray valves can be used for large-area protection.

3. Production Cycle and Efficiency

High-speed production lines require fast-response solenoid valves or jet valves, while high-precision applications can use servo-driven dispensing systems.

4. Automated Integration Requirements

Leiko coating valves support linkage with PLC and vision positioning systems to achieve fully automatic coating, reduce manual intervention, and improve consistency.
