Enjet Co., Ltd., headquartered in Suwon, South Korea, is a technology company founded in 2009 that develops advanced manufacturing solutions centered on proprietary electrohydrodynamic (EHD) printing, coating, and dispensing systems for ultra-high-resolution patterning and thin-film deposition. Its nanojet printers and coaters are used across industries such as displays (including OLED and micro-LED), semiconductors, PCBs, camera modules, and biomedical applications to replace traditional vacuum processes with precise, scalable additive manufacturing techniques.
iEHD Printer
High resolution and high precision printing technology
enjet's proprietary printing technology surpasses the limits of conventional industrial printing equipment, achieving high-resolution and high-precision (<1μm) printing. By precisely controlling various factors, seamless dispensing of ultra high viscosity (<50,000cPs) materials at micrometer resolution can be achieved. The technology allows for precise position control and printing of femtoliter (micro-diameter) conductive ink tailored to microchip manufacturing processes. Single and multi (512) nozzle systems are available, in standalone systems (EHDison-H or eNanojet, e.g.) or as printheads for customized integration.
Main applications are:
-
Precise repair of chip bonding (wiring) or μLED defects (open/close) in one tool including automatic inspection, laser trim/remove/cure/clean and pick & place
-
Large chip underfill
-
micro-lens array, bond pad
-
catalyst/battery coating
-
3D wiring, pattern array
-
TGV fill/repair​
iEHD Dispenser
Dispensing via Electric Field & Fluid Control
High-viscosity, ultra-precision dispensing in areas beyond the capabilities of conventional dispensers. Additionally, applying an electric field prevents droplet (sputtering) formation and ensures reproducibility, enabling more stable dispensing. It allows ultra high viscosity (<100,000cPs) printing at high resolution (<100μm) while minimizing splashing phenomenon and ensuring small wet-out (keep-out zone). Available as printhead or standalone system (eNanojet, e.g.)
​
Main applications are:
-
bonding and sealing
-
2D edge side electrode printing
-
chip underfill​
iEHD Coater
High-Viscosity Coating Solution
enjet's spray nozzle technology allows for fine spray coating of high-viscosity inks, significantly increasing the directionality of the liquid and reducing material consumption. It solves the bubble problem and ensures uniform flow rate control, enabling material savings up to 50%. Available in application-specific tools as part of the eNC series.
Main applications are:
-
Secondary battery cell or fuel cell catalyst coating​
-
EMI (electromagnetic inference) 3D shielding
-
conformal coating on both the surface and sidewalls of large-area substrates
-
anti glare/finger coating
