SCREEN Develops High-spec Direct Imaging System for PCBs

SCREEN PE Solutions announced to finalize development of high-production direct imaging system “Ledia Twin”. The system supports pattern formation on printed circuit boards (PCBs) such as HDI (high density multilayer) boards and IC substrates, for which demand is rapidly increasing for 5G applications. Ledia Twin is scheduled to be released in January 2021.

With its ability to perform pattern exposure of apertures with a diameter of 60 μm in solder masks, Leida Twin continues the Ledia series' strength in high-precision imaging. It also adds a new dual stage mechanism. While exposure is being performed on one of these stages, the board on the other can be replaced and its alignment marks scanned. This achieves a significant reduction in work time. The imaging time itself has also been shortened by the adoption of a more powerful light source. Together these and other innovations improve productivity by up to around 50%.

Tohoku Pioneer Agrees to Supply OLED to PolyPhotonix for its Sleep Mask Treating Diabetic Retinopathy

Tohoku Pioneer, a consolidated subsidiary of Pioneer, agreed to supply state-of-the-art OLED panels (planned in spring 2021) for Noctura 400, a sleep mask used to treat diabetic retinopathy that was developed by PolyPhotonix, a UK based bio-photonic research company.

Diabetic retinopathy is a complication of diabetes caused by high blood sugar levels damaging the back of the eye, which can cause blindness if left untreated. Aiming at reducing the symptoms of diabetic retinopathy and helping patients recover, PolyPhotonix's sleep mask, designed to be worn at night, delivers a precise dose of light therapy during a patient's normal hours of sleep in a home setting. The sleep mask equipped with a lightweight battery that does not interfere with sleep realizes long-term stable and sufficient light irradiation by adopting a highly efficient and long-life OLED panels newly developed by Tohoku Pioneer.
