3D Digital Printing Conformal Coating Machine

Pixel-level precision jetting with 1,000+ independently controlled nozzles — digital, layer-by-layer PCBA protection without masking.

1,000+ Nozzles 0.016mm Layers No Masking Needed

Descrição do produto

The 3D Digital Printing Conformal Coating Machine applies inkjet-based digital control to PCBA protection. Instead of spraying coating material across a board and masking off sensitive areas, the system jets material through more than 1,000 independently controlled nozzles — each one turned on or off individually to build coating exactly where it's needed and nowhere else.

Coating is built layer by layer, with each layer cured instantly under UV-LED before the next is applied. This digital, additive process gives full control over thickness and geometry across a single board — thin-film protection in most areas, with selective reinforcement built up only where required.

Because keep-out zones are defined in software rather than physical masking, the system automatically avoids test points, connectors, gold fingers, and sensor windows — reducing labor, rework, and material waste while improving first-pass yield.

How It Works

Digital, Layer-by-Layer Coating

From board data to cured protection, entirely software-defined

Step 01

Import Board Data

CAD/Gerber data defines coating zones and keep-out areas digitally — no physical masking required.

Step 02

Pixel-Level Jetting

Over 1,000 nozzles jet ~80 pL droplets at up to 400 dpi, coating only the defined target areas.

Step 03

Instant UV-LED Cure

Each layer cures immediately after jetting, preventing dripping, spreading, or edge distortion.

Step 04

Build Up in 3D

Layers stack digitally to create variable thickness — thin film in most zones, reinforced protection where needed.

Caraterísticas principais

Ten advantages of digital jetting for PCBA conformal coating

Pixel-Level Precision Jetting

Over 1,000 independently controlled nozzles enable fine, selective coating of targeted areas.

Ultra-Fine Droplet Control

Minimum droplet volume of approximately 80 pL, with jetting resolution up to 400 dpi.

Ultra-Thin Film Formation

Single-layer thickness as low as 0.016 mm, ideal for lightweight, high-precision protection.

3D Multi-Layer Stacked Encapsulation

Layer-by-layer jetting and curing enables fully digital control of thickness and geometry.

Sharp, Clean Coating Edges

Edge control accuracy within 0.05 mm, significantly reducing overspray.

Precise Keep-Out Zone Avoidance

Automatically avoids test points, connectors, gold fingers, and sensor windows without masking.

Localized Variable Thickness

Enables thin-film protection, selective reinforcement, and 3D encapsulation on the same PCBA.

Instant UV-LED Curing

Curing immediately follows jetting, minimizing dripping, spreading, and edge distortion.

High Material Utilization

On-demand jetting eliminates atomization waste, reducing material consumption by roughly one-third.

Intelligent Automated Maintenance

Supports automatic humidification, nozzle-clog detection, fluid path circulation, and printhead condition monitoring.
