Electronic parts

We are making a prototype and manufacturing electronic parts such as flexible wiring board(FPC), contactless IC card, antenna substrate for tag centering on electronics relation by making excellent use of our own printing and etching techniques with graphite materials and various conductive paint in order to meet all kinds of customer’s needs.

Product details

Flexible printing wiring board(FPC)

Achievement of cost-performance by consistent self-manufacture from copper ply base material, patterning and all kinds of plate processing to contour cutting.
We respond to module evolved to high density, smaller and lighter with confidence and reduction of total cost.

Solder mounting for LED on also PET film is possible due to use special heat resistance adhesive. Wiring pattern does not interrupt view when applying to glass so this product can be used in a wide-range of fields.

Application : LED substrate for pachinko, slot and solar for window.

Roll FPC & Reel FPC

The product patterned continuously on roll base material can be supplied in a roll.
We can provide any long wiring board. We have some exposure machine of different unit size such as large or medium size so meet customer’s needs flexibly.

Application : Thermistor substrate

Antenna for IC card

Film antenna in a roll of width of max.500mm is provided with our high-definition etching technique and screen printing. Both copper and aluminum foil is available.
Condenser of back side with our own through hole technique with silver paste is available.

Low resistance antenna wiring with electrolytic copper foil.
Many experiences of UHF frequency for long-range communication due to stabilize with low resistance.
It is suitable for high-definition antenna pattern because of no heat generation at etching.

Application : All sorts of label(medical, security), banking facilities card

Aluminum etching antenna

It can be supplied at lower cost than copper type.
Aluminum foil is easily influenced of oxide layer but it keeps better connection reliability than caulking method by using of our own silver paste.

Application : Driver’s license, passport

Small tag for NFC antenna

From push to touch. Detection of capacitance change by person’s touching.
Full-flat excellent design is available. Whelming reliability without breakdown or trouble in comparison with automatic intermittent switch.
We can provide various capacitance touch sensor based on screen printing technique from years of experience with various conductive paint as well as PE-DOT. Besides we can provide the products bundled with control IC to drive sensor.
We can meet wide range of customer’s needs from transparent touch sensor with PE-DOT to competitive one with our own graphite paint.

Screen printing substrate

Our through hole is the technique for connecting two sides wiring by printing conductive paint (silver, graphite) on both sides with screen printing method and pouring paint into through hole after making a hole in base material.
Aluminum foil is commonly affected by oxide layer but it keeps reliability of connection more than caulking method by use of our own silver paint.
PET wiring board printed by conductive paint on thin polyester film is very thinner than PCB board, suitable to lighter and compact module and more reasonable material than FPC.

Punching ・ slit of various film
