Heatsinks: areas heatsinks are: horizontal deflection: K/W. vertical deflection: extruded heatsink with K/W. EHT: K/W. SMPS: K/W.
Mounting studs heatsinks: heatsinks horizontal deflection, SMPS mounted special mounting studs. each heatsink these studs connected ground plane circuit ensure heatsink correctly grounded. heatsink vertical deflection mounted with screws. Again these screws connected ground define heatsink's potential. Clips device mounting heatsinks. Note: mains voltage interrupted board between filter output mains switch. This connection must made wires soldered between appropriate points board. reason implementing this connection board lay-out that requires much space.

PRINTED CIRCUIT BOARD LAYOUT
Application Note AN97032
next pages following drawings found: component placement with position numbers seen from component side; component placement with values seen from component side; placement with position numbers seen from solder side; copper pattern printed circuit board.
board dimensions are: long wide.
Lay-out hints
common ground track should kept clean possible. This means that only currents should flowing through this track indicating that current short circuited it's source! Therefor will find resistor capacitor supply filters every stage.
Ground track:
Focus: focus signal TDA4854 it's reference ground should kept close each other input focus output amplifier high gain this output stage (and neighbourhood circuit well long distance between source amplifier). Vertical deflection: Keep vertical drive signals TDA4854 close together places avoid coupling magnetic fields loop. Horizontal deflection output stage: Keep flyback capacitor diode horizontal deflection stage located close together damp forward recovery ringing flyback diode. leakage inductance driver transformer tracks between transformer line output transistor should kept short possible. X-ray protection: connecting points R129/R130 R130/R131 very sensitive their high impedance. These points should therefor kept small possible away from points with high voltage swing (i.e. collector voltage BUT11A).

CICT decide proceed with plans make available P83Cx81 family monitor microcontrol2 lers. This family originally intended serve market monitors which were controlled. P83Cx81 positioned cost down version P83Cx80 family. However following reasons this positioning longer makes sense: most customers think P83Cx81 pins enough they prefer pins P83Cx80 versions. actual cost difference between P83Cx80 P83Cx81 very small. P83Cx80 family also easily used controlled designs, only controlled designs. have customer orders currently P83Cx81.
Therefore will proceed with development this family. P83Cx80 family course affected this decision. have customer interest P83Cx81 family please inform them this decision ASAP. those customers investigating CCM420 demo monitor (which uses P83Cx81) from please informed that functionally P83Cx81 subset P83Cx80 CCM420 software also P83Cx80. have further questions please contact directly.
