Simply put,
Manhattan Style
of construction uses small pieces of copper clad
(the “pads”) glued to a main copper clad circuit board (the
“substrate”) that
serve as component mounting plat
forms.
The electronic components are then
mounted and soldered onto these pads.
The main “substrate” board serves as
the ground plane. Not only is this technique an easy and neat way to build a
circuit, it also produces a very quiet circuit due to the solid ground plane.
One popular and easy method for making the pads is using small pieces of copper clad from a larger piece.
 
.
Making the “pads.”
  Some use round pads from a punch or cut the pads
out of the main board with tin snips.

Building the circuit.
The pads are then glued onto the main board for mounting
the components. Super glue is usually used for affixing the pads to the main
board.
The pads are positioned more-or-less in circuit order, similar to laying out
a printed circuit board (PCB).

A little forethought of layout goes a long ways.
After the layout is decided, it is best to “build as you go along” ... that is, glue
down a few pads, solder the components, then move to the next few pads, to
keep from working yourself into a corner or running out of room.
 
Some of my listings are lightly sanded.
I try to remove any stains and scuff marks.
It also helps the bonding of dry film or transfer paper.
