Securing world-class technological competitiveness
through continuous innovation and technology development

JNTC has secured the advanced technology of digital devices early on by reading the trend of future technological changes.
It has established a high market entry barrier and competitiveness by developing high value-added connector products such as C-Type and waterproof function. We have applied to tempered glass an antimicrobial function, as well as various tempered glass technology such as AG (anti-glare), AR (anti-reflective), SLG (Sapphire-like Glass; high hardness glass), etc. In addition, we have secured mid- to large-sized 3D thermoforming technology that can be applied to high-end tablets and automotive tempered glass.

Technology	Details	Notes
Process Technology	Glass protection technology between processes (2010 ~) In order to reduce handling defects between processes, we printed protective ink on the surface of the full sheet (1900*1460mm) glass provided by our raw material vendor to improve the yield.	-
	Laser cutting technology Enhanced productivity using laser beam for cutting small size watch & camera glass.	-
	Water Jet cutting technology This is a method of processing a full glass sheet (1900*1460mm) into the customer's smartphone window size. We have increased the production quantity by stacking and cutting glass with high pressure water with grindstone.	-
	CNC In-Line automation technology The process of manual inserting/removing glass has been inlined and changed to automatic, reducing the number of people by 1/30.	Labor cost reduction, enhanced competitiveness
	Vision inspection technology The human inspection of tempered bare glass was replaced by the development of an automatic vision inspection machine, achieving cost reduction and quality stability.	Labor cost reduction, enhanced competitiveness
	AF Coating technology By developing a sputter method equipment from the E-beam method, an AF coating method, the number of coatings has been improved from 250 cells to 1,000 cells, increasing productivity four-fold.	-
	Adhesion technology Using sputter equipment, which was made by JNTC, we own technology for high hardness glass as well as low relectance AR.	-

3D Window	3D asymmetric curvature thermoforming technology We developed a technology for thermoforming 2D flat glass into a 3D asymmetric curved surface and applied it to new products, satisfying the customer's dimensional tolerance without secondary processing, increasing production volume and reducing labor costs through loading/unloading automation.	Internally developed
	Polishing technology Developed gloss polishing machine and process for thermoformed 3D asymmetric curved products and applied to new products.	Internally developed
	3D Deco lamination technology Exclusive technology: laminating deco film to 3D asymmetric curved windows according to the shape of the glass, and attaching film to parts with small R values.	Internally developed
	Printing on 3D-shaped glass This is a technology for printing on 3D-shaped (curved) glass, ranging from 2-bended to 4-bended shapes. JNTC has implemented internalized silicon pad printing technology in order to quickly respond to many different curved shapes.	Internally developed
Coating	Antimicrobial coating technology Silver used for general antimicrobial has a risk of allergy. In our company, we have implemented antimicrobial using hypoallergenic zinc oxide.	-
Automotive 3D window	Large-size 3D asymmetric curvature thermoforming technology We developed a technology for thermoforming large size 2D flat glass into a 3D asymmetric curved surface and applied it to new products, and satisfied the customer's dimensional tolerance and appearance (1270*400mm) without secondary processing.	Internally developed
	Large-size AG technology This technology was implemented by etching Anti-Glass (AG) on a large size 1460*380mm 2D flat glass.	Internally developed
	Large-size 3D Curved silk print technology We have developed a semi-automatic facility and technology that can directly print Deco on large size 3D Curved Glass.	Internally developed

Process Technology	Insert Hoop System technology A method for precision connectors by insert injection. Established a system that automatically loads into insert injection to produce precision pressed products.	Enhanced productivity
	Auto-assembly technology Automatic machine production is an assembly of several element technologies (pneumatic pressure, sensor, control, etc.). Ensured productivity by configuring the optimal assembly machine, combining element technologies suitable for the characteristics of each product.	Enhanced competitiveness
	Component welding technology A production process incorporating welding technology as a method to withstand the load applied to the connector. Precise position control and multi-point welding technology mechanisms are configured to enable welding to the required position.	Enhanced competitiveness
	Vision inspection Established automatic vision inspection system for inspection of dimensions and foreign objects.	Enhanced productivity & competitiveness
	Automated packaging technology Prevents pre-mixing errors as products that passed final inspection are automatically packaged at the facility.	-
Waterproof Connector Technology	Waterproof potting process Established a precision control system for waterproofing materials inside and outside of waterproof connectors.	-
	Air Leak test (Waterproof test) The waterproof inspection requires a certain degree of air pressure, pressurization, maintenance, etc. Implemented a facility mechanism to reduce time and enable a batch inspection in consideration of inspection time.	Enhanced competitiveness
	3D flatness inspection technology Implemented an inspection system to ensure quality through precision measurement technology according to product characteristics.	Enhanced competitiveness
