PURPOSE: A focus pack of a flyback transformer is provided to reinforce the insulation property of a volume substrate(120) without hardening process or inserting an insulating resin. CONSTITUTION: A focus pack of a flyback transformer includes a volume substrate(120), focus and screen resistor patterns(130,130'), an aperture(140), an arc closing member(150), and an arc compartment(170). The volume substrate(120) is implemented inside of the flyback transformer(FBT) focus pack. The focus and screen resistor patterns(130,130') are curved to be formed on the upper surface of the volume substrate. The aperture(140) is formed on the focus and screen resistor pattern curve whose variable touch point is rotatable with a reference of a central point of the volume slider. The arc closing member(150) is formed on one side of a pattern connector(130'') which connects the focus and screen resistor patterns curved on the upper surface of the volume substrate. The arc compartment(170) is inserted in the arc closing member of the volume substrate by coming out of the rear surface of the case(160) of the focus pack(110).
