New technology

On this page we will introduce processing technology unique to techno print.

Fine metal mesh pattern processing

We support pattern processing of transparent fine metal mesh film.

Metal mesh film heater

Prevention of snow accretion and snow melting by using LED heads and rear lights instead of conventional halogens.
Measures against frost and snow melting on the windshield in front of the camera for automatic safety brakes for ADAS and autonomous driving.

Metal mesh film antenna

Supports 5G mini base stations and supports transparent antennas for buildings and vehicles.

Outer diameter of film substrate ~ A4 (PET / PC etc.) ... * Can be considered up to 300 x 300mm (conventional glass substrate can also be used)
2μm~ Cu wiring processing (consult us for conventional thin film patterning and plating build-up)
* L / S of the pattern depends on the film quality, thickness, length and shape of the base material and resist material.
* Please contact us for assistance in developing new materials for fine metal mesh processing.


Pattern examples Straight lines and corrugated shapes are also supported. (Enlarged view)

Transparent resist coating and patterning

Transparent resist coating and microfabrication patterning 2 μm-

specification

Pattern width

2 μm-

Film thickness

0.6~30μm

Coating size

Can be considered up to 300 x 300mm

Application examples
・ Because it is insulative and transparent, it can be used as a protective film or interlayer insulating film for substrates instead of conventional Pi.
・Since it is photosensitive, partial patterning is possible.
・For resist for full additive plating for metal mesh film processing.

* The processing details depend on the length and shape of the pattern and the substrate quality.
* In the future, we will challenge L / S below 3μm, so please contact us.

MEMS(Thin film metal sensor processing)・・・Alcohol breath sensor

Patterning technology for multilayered thin film of Techno print contributes to processing of MEMS sensor parts.

* Patterning of metal thin film and coated insulating film realizes sensor part and its heater function.
Furthermore, sensors can be miniaturized as individual sides.

Illustration is an alcohol breath sensor linked with a smartphone.
* The real thing and the image are different.

Electrochromic・・・NIMS・WASEDA・TAMA Art University Joint development project

An electrochromic type light control glass that can change light shielding state by applying electricity has been used for windows of airplanes and the like in recent years.
However, until now, there is no choice but to adjust the light shielding condition throughout the glass, and after shading it was impossible to enjoy the view outside the window.
This time, the research group developed a light control glass that changes the gradation using a polymer (organic / metal hybrid polymer) with electrochromic properties that we have studied so far.
Detail is here.

Techno print thin film processing technology is also utilized for pattern development and patterning processing on the ITO film formed on the glass of this product.

Electrochromic

It was also featured on World Business Satellite "Tretama" broadcast on December 19, 2019.

ITO heater processing

It contributes to product making even by ITO patterning and Outline processing, and ACF crimping of wide FPC.

principle

When the electrode is energized, Joule heat is generated in the transparent conductive film,
heated with the glass, far infrared rays are emitted from the glass surface.

ITO heater

Formation of fine structure

At TCN, we provide customized types of μm precision with various resist agents.
Pattern shape can be straight / circular (cylindrical)
Aspect ratio 5: 1 (film thickness 50 μm or more) possible, (3: 1 actual results)

  • I want a rectangular unit of μm in base with good accuracy, where should I order?
  • Where is the place customized even in small quantities?
  • I want you to customize various heights and shapes!

Thick film resist processing

Application example

Evaluation of tracking performance of adhesive, adhesive film, filler (inside of semiconductor PKG, etc.)
Micro folder such as micro LED
Cover glass spacer for solar cells etc.

In addition to simulation, evaluation and verification that is close to the actual machine is possible.
By creating a mask, it is possible to divide multiple shapes by changing the line width such as L shape, straight line, circular shape (cylindrical) etc. on the same board.
Aspect ratio 5: 1 (film thickness 50 μm or more) possible, height 2 to 100 μ possible
* However, the same height is on the same board.
Substrate size is easy to use up to 300 mm in large format □ 50, 100, 200 mm and any size can be cut.
Glass / silicon wafers etc are possible as base material.

Evaluation of viscosity, flow and followability of various adhesives · coating materials etc.

Industry first! Development of low load TP compatible with multi-touch
※ In the G / G resistive film method

By significantly reducing the load compared with the conventional G / G, light multi-touch input is realized.
By sealing the two glasses, it corresponds to use under harsh environments such as in the car under the scorching sun.
It is hardly affected by noise such as electromagnetic waves.
It is excellent in waterproof and moisture, and there is no malfunction due to waterdrop adhesion.
