The Art of "Manhattan" Style PCB Construction

"Manhattan Style" is a technique for constructing electronic circuits by gluing pads or traces to make "islands" of separate conductivity on top of a base material. The pads or traces are cut (with a shear^ or nibbler^) or punched^ from copper clad board or thin sheets of metal ,or clipped and bent from solid wire, and affixed with super glue or other adhesive. Component leads are then soldered to the top of the pads and traces to build the circuit. A metalic base board can provide a ground plane.


Here are some examples of circuits made using Manhattan construction: (thanks to Carel Mulder - PA0CMU, and Paul Harden, na5n for permission) used by permission used by permission

Of course, if you really don't want to use a PCB, you don't have too...

Here is an Arduino made on a sheet of high temperature plastic:

Actually, you can make a circuit on nothing at all:

That is actually a USB AVR programmer, believe it or not.. the USB cable hasn't been soldered on yet. More at:

A lovely example from Which was apparently taken without credit from: ?

How it's done:

Here are a few pictures and descriptions to give the general idea. There are several very good tutorials listed at the bottom of the page for more detail.

A harbor freight punch used to make small round pad from copper clad board. A harbor freight punch held in a vice; used to make small round pads from copper clad board. Other methods of making pads include cutting small square pad or long strips with a shear or PCB saw, or using a sheet metal "nibbler"

The long strips are most useful for surface mount designs or as buss bars. Wire can also be used to connect separate smaller pads.

You can also make isolated pads in a solid PCB with spot weld drills at Harbor Freight. These drills have a spring loaded center pin that keeps the boards from wandering while you drill them. You can also drill very small pilot holes through the board to make matching pads on the opposite side of the board for feed through connections.

PCB padsPCB pads made from the above punch, glued to a base of copper clad board. The tops have been tinned with solder, ready for component leads.

Care must be taken to remove any burs or "flashing" of copper that might short the top of the pad to the base ground plane. This is also important for safety.

Acetone can be used to remove the super glue holding the pads if they must be repositioned, but this can be very difficult to apply to only one pad in a tight layout, so get your pads set right before adding the components.

Resistors soldered to manhattan pads and ground plainComponents can be soldered vertically or horizontally between pads or from pads to the ground plane. Notice that the ends of the leads are always parallel with the surface they are being soldered to.

As this excellent example from chuck adams, k7qo shows, Manhattan construction can be very artistic.

These strips were made with a nibbler and a shear.

Super glue seems to be the best option for mounting the pads or strips on the base copper clad board.

IC pad made by cutting isolated segments on a copper clad board.Pads for Integrated Circuits can be made by cutting away the copper from a piece of copper clad board to make isolated segments matching the spacing and number of pins.

IC socket soldered to padICs can be soldered direct to pad or sockets can be used. In either case, the leads should be bent over to provide a larger contact area with the pad.

An IC in dead bug constructionIC's can also simply be glued in place upside down and components or wires soldered to the IC leads. This is often called "dead bug" construction.

Another option is to attach the IC right side up with a spacer under it or by soldering the leads at the corners to the regular pads as above, then bending the other leads out flat above the base PCB and soldering directly to them. One might call this "live bug" construction.


Surface mount is also very possible with Manhattan techniques. Note the ease of use of through-hole components without holes as demonstrated by the resistor in the lower right corner.
