Roll-to-roll (R2R) equipment technologies

　Home ⇒ Technology ⇒ Roll-to-roll (R2R) equipment

Four roll-to-roll (R2R) equipment were introduced.
・Substrate width: 30cm
・Substrate types: ultra-thin glass, stainless steel fold

◆ R2R vacuum deposition (CVD and sputtering) (KOBELCO)

This R2R vacuum deposition equipment provides sputtering and CVD (Chemical Vapor Deposition) [1,2]. In the sputtering process, the deposition temperature can be changed in the range of -20℃～250℃ [3-5]。

This equipment has been applied to electrode deposition (ITO etc.) [4,5], barrier layer deposition on plastic films [6], etc.

◆ R2R screen printing (SERIA)

This R2R screen printing equipment utilizes the “zero-gap” technology which was developed by SERIA [7]. The “zero-gap” is realized by such a novel system that a flexible substrate is sandwiched between roll-type printing roller and flat stencil mask, improving printing accuracy.

This equipment has being applied to the printing of etching paste for photolithography-free patterning of electrodes [4,5], the printing of insulating materials [8], etc.

◆ R2R gravure offset and flexography printing (Komori Machinery/ Taiyo Kikai)

This R2R gravure offset and flexography printing equipment has a gravure offset printing unit developed by Komori Machinery and a flexography printing unit developed by Taiyo Kikai [9].

◆ R2R wet cleaning (FEBACS)

This R2Rwet cleaning equipment is applied to wet cleaning processes of flexible substrates.

The effect of wet cleaning on barrier property of flexible film was investigated by using roll-to-roll (R2R) wet cleaning equipment, finding that wet cleaning improves barrier property [10].
