Latest Patents
Sakamoto's latest patents include a screen printing apparatus designed to enhance the efficiency of applying paste onto substrates. The first patent describes a screen printing apparatus where a squeegee head moves over a mask plate, allowing paste to be printed through pattern holes. This design features slide contact portions that form front and rear walls in the squeegeeing direction, effectively reserving cream solder within a printing space. The filling surface of the apparatus rolls the cream solder, enabling it to fill pattern holes without pressurizing the material, thus preventing leakage. The second patent outlines a method and apparatus for screen printing that utilizes a filling member at the lower end of the squeegee head, which forms an acute angle with the mask plate. This design ensures that any excess paste is wiped away by a wiper that forms an obtuse angle with the mask plate, further refining the printing process.
