Abstract
The present invention is directed to a cathode ray tube having a neck portion and a funnel portion at one end of the neck portion. A yoke extends around the neck portion and has a printed circuit board mounted thereon. The printed circuit board includes a plurality of pins mounted on and projecting in the same direction from the board and a plurality of electrical components mounted on the board and electrically connected in a desired circuit and to the pins. The pins are shortened so as to be of a length that at the operating frequencies of the yoke they do not emit a substantial amount of electromagnetic radiation.
Claims6
In a cathode ray tube having a neck portion, a funnel portion, a yoke extending around the neck portion and a printed circuit board on the yoke, said printed circuit board comprising:
- a board, at least one pin mounted on the board and projecting from a surface thereof, and electrical components on the board and electrically connected to the pin, the pin being of a length such that it does not emit a substantial amount of electromagnetic field radiation at the operating frequencies of the yoke.
