Assembly of oscillator periphery


TV tuner, PLL oscillator and frequency divider are set up on a sheet copper.

Although even the sheet of pure copper is good as chassis, I used the printed board.
TV tuner and PLL oscillator handle the picture signal, then the ground needs to be connected firmly.
The tuner solders and fixes directly to the printed board. Soldering iron in this work uses the big thing of electric power capacity. The one that is 80W was used.
When electric power capacity is small solder is not able to attach well without melting.
