Step 8: Remaining Top-Side Components
Install precision 100K resistors into their places. They must be elevated above the
board as shown on the picture. This method of installation is required by the resistors'
design and it helps to keep values within tolerance. Then install rectifier diodes and
aluminium capacitors. All of those are all polarized components! As with the small-
signal diodes, cathodes of the rectifier diodes are marked with stripes on diodes and
footprints. All holes for the positive pins of electrolytic capacitors are marked with the
“+” sign. All positive pins on capacitors are longer than negative pins
Finally, install the vertically oriented resistors. The allowed height of the resistors
must be non greater than 8 mm to ensure that leads do not touch the surface of the
panel.
