Technological direction for Thermal Print Head

摘要

TPH is printing devise that generates Joule heat and transfers Joule heat to medium. Therefore TPH design shall be defined by degree of heat generation uniformity and heat transfer uniformity. So Toshiba Hokuto Electronics Corp. thinks it is important to find vital control parameter for many kind of demand. Glaze and/or protective layer are vital parameter, so Toshiba Hokuto Electronics Corp. will improve current design and/or process by them for more high performance
