ROHM EcoGaN™ Power Stage ICs: Smaller Size, Lower Loss
ROHM has developed high-speed, highly reliable thermal printheads: TE2004-QP1W00A / TE3004-TP1W00A. These devices are optimized for barcode label printers applied in logistics and inventory management.
In recent years, the growth of the e-commerce (EC) market and diversifying customer needs have increased the demand for logistics and inventory management labels. Conventional thermal printheads, however, are limited to printing speeds ranging from 250mm/s to 300mm/s. In response, ROHM developed high speed and highly reliable thermal printheads that leverage novel structures and technologies. The key goal: achieving a level of print quality and durability that exceeds conventional limits.
The TE2004-QP1W00A (203dpi) and TE3004-TP1W00A (300dpi) significantly improve on the substrate material, structure, and wiring pattern over existing products. In particular, the heating elements, which affect printing speed and quality, adopt a new design using ROHM’s original 3D processing technology to achieve an industry-leading print speed of 500mm/s – approximately twice as fast as conventional products.
On top, applying a two-layer high-hardness protective film to the head increases resistance to abrasion and static electricity for high-speed printing along with corrosion caused by moisture and salt, extending service life considerably.
