ASYMTEK SC-400 Precision Coating Jet

Overview

The SC-400 PreciseCoat® Jet introduces advanced selectivity and flexibility to conformal coating applications. Leveraging ASYMTEK’s industry-leading jetting technology, the SC-400 delivers superior precision and control when coating small, densely populated assemblies with strict keep-out zones.

The jet stream reaches areas inaccessible to traditional applicators, thereby reducing the need for masking, increasing throughput, and enhancing process repeatability. Fully compatible with Select Coat® SL-940 and SL-1040 conformal coating platforms, the SC-400 can be configured as part of a multi-valve system to support hybrid coating strategies.

Maximize Yield with Selective Precision Coating

Achieve uniform coating thicknesses of 15 microns using solvent-based materials—while precisely avoiding keep-out zones and coating hard-to-reach areas inaccessible to traditional spray and film coaters.

Key Advantages

● Easily accesses tight geometries and navigates around tall components.

● Coating speeds up to 500 mm/sec (20 in/sec) for high-throughput production.

● Delivers consistent dots and lines on warped or complex substrates

● Supports coating materials ranging from low to high viscosity

● Reduces masking, rework, and maintenance time

Ideal Applications

● High-density, fine-pitch PCBAs

● Selective coating around high-value or sensitive components

● Thin-film applications requiring high precision and uniformity

● Complex assemblies with hard-to-reach coating areas

● Multi-valve coating workflows requiring a balance of precision and wide-area coverage

Advantages in Cost of Ownership, Yield, and Setup Time

● Lowers Total Cost of Ownership (TCO) through ultra-selective spraying, reducing masking, overspray, and material waste.

● Improves first-pass yield by precisely coating narrow geometries and hard-to-reach areas without encroaching on keep-out zones.

● Reduces rework and scrap by maintaining consistent dots and lines, even on warped or complex substrates.

● Increases production efficiency with coating speeds up to 500 mm/s, maximizing equipment utilization

● Enhances process repeatability, minimizes variability, and supports stable, high-quality production

● Achieves greater uptime and scalability through compatibility with Select Coat® SL-940 and SL-1040 platforms and support for multi-valve, mixed-coating strategies
