\n

Electrodes and wiring patterns are processed by a roll-to-roll etching process.

\n Our strength is that we have two processes, photolithography and screen resist, and can process with high precision<\/p>\n<\/div>\n

ITO \/ Cu thin film patterning<\/h3>\n

High-precision wiring processing with Line \/ Space = 10 \/ 10\u00b5m, double-sided processing, and large area are available.<\/p>\n

Photo etching processing flow<\/h4>\n

\"\"<\/p>\n

Double-sided patterning<\/h4>\n

It can be processed on both sides of the film, not just one side. Alignment with an accuracy of 10um or less is achieved.<\/p>\n

\"\"<\/p>\n

Handling large areas<\/h4>\n
\n
\n

Supports large area patterning with a mask size of up to 500 x 1,000mm
It responds to a wide range of needs such as multi-cavity for mass production and production of large modules.<\/p>\n<\/p><\/div>\n

\"\"<\/div>\n<\/p><\/div>\n

Cu alloy thin film patterning<\/h3>\n

We can also pattern copper alloy thin films used for strain gauges.<\/p>\n

Raw material
Cu alloy thin film (t = 100-200nm) \/ Base film (PET)
mask size 500 \u00d7 500\u339c
Post-process such as insulation coating processing and individual cutting is also possible.<\/p>\n<\/p><\/div>\n

Screen resist etching process<\/h2>\n
\n
\n
\n

We have a process for resist processing by screen printing.

Since no photomask is required, low-cost production is possible.<\/p>\n<\/p><\/div>\n
