Prototyping Board 8" x 5

The Electronix Express prototyping board measures 8" x 5" and provides a double-sided solder pad for every hole. It is intended for engineers, students and hobbyists who need a reliable platform for building and testing custom circuits. Power buses are integrated to simplify distribution across the layout.

Double-Sided Solder Pad per Hole

Each hole on the board is surrounded by a solder pad on both sides, allowing components to be soldered from either face. This construction supports dense component placement and makes it easier to route connections on complex prototypes. The feature is the primary factor when choosing this board over single-sided alternatives.

Thermal and Power Characteristics

The board is a passive substrate with no active components, so it generates no heat and produces no noise during normal use. Power draw depends entirely on the circuit assembled by the user and the external supply connected to the power buses. No onboard regulation or cooling is required.

Questions about this item

How does the 8" x 5" size translate to usable prototyping space on a workbench?

The board gives a generous rectangular area for laying out circuits, with double-sided pads at every hole so components can be placed on either face and traces routed across both layers.

What does the double-sided solder pad per hole design mean for circuit density and rework?

Each hole has a copper pad on both sides, allowing components to be soldered from either face and letting you run connections on the top and bottom without jumpers.

What mounting options suit the board's dimensions and power-bus layout?

The 8" x 5" outline fits standard project enclosures and can be secured with standoffs; the integrated power buses run the length of the board for convenient supply distribution.
