CERAMIC BOARD FOR IMPROVED INSULATION OF FBT FOCUS UNIT

摘要

The present invention provides a ceramic substrate of the FBT focus unit which can prevent product defects due to arc leakage by securing insulation between the focus and screen conductor patterns printed on the ceramic substrate of the focus unit installed on one side of the FBT. In particular, the separator insertion hole 160 and the insulation hole 180 are formed between the adjacent conductor patterns 140 and 150 printed on the ceramic substrate 130 of the focus unit 110. The isolation layers 170 protrude from the inside of the focus cover 120 to which the 140 is coupled, so that the isolation layers 170 are tightly inserted into the separator insertion holes formed between the conductor patterns 140 and 150 of the ceramic substrate 130. The gist is to be installed to be fixed.
