When laying out PCB boards, you usually insert ground plane or connect copper pour to ground. This improves noise immunity and system performance.
You know the importance of grounding very well. A lot of application notes also talk about this:
- Successful PCB Grounding with Mixed-Signal Chips - Follow the Path of Least Impedance - Maxim Integrated
- Printed Circuit Board Design Issues - Analog Devices
Even in prototypes, people care about grounding all the time:
- Breadboarding and Prototyping Techniques - Analog Devices
- Prototyping Methods - Dr. Charles Sullivan, Dartmouth University
You would think that this is not a bad design since the ground looks ok:
However, when building circuits on bread board or PCB protoboard, you usually don't get a ground plane or a big piece of copper as ground. Instead, you fly wires everywhere.
These look ugly:
Many components need to be connected to ground, but you never get a ground on bread board or conventional PCB protoboard.
SpeedyProto gives you a ground, with thermal relief ground connection dots accessible from every pad.

Below are some soldering examples using SpeedyProto:
The first two pictures are the top and bottom side of a SpeedyProto Mega board. I soldered several common components to show case the usage of the board. On the top side, a SOIC-8 package IC and a through hole capacitor are soldered. The SOIC-8 package IC are soldered directly on to the component pads using solder bridges. No wires are used.
On the bottom side of the board, there are through hole as well as SMD components soldered.
On the bottom side of the SOIC-8, SMD capacitors can be directly soldered on pins. De-coupling capacitor can be soldered on pin and directly connected to the "ground dot".
The through hole resistor is connected to two component pads with one pin grounded easily using a solder bridge from component pad to the "ground dot".
0603 SMD capacitors and resistors can be easily soldered between component pads as well as between component pad and "ground dot".
Two SMD components can be connected together easily by sharing one component pad.
The bottom side of the through hole capacitor can be grounded easily using a short solder bridge.
Below is an example of a heart rate monitor circuit built on SpeedyProto. This kind of precision circuits are sensivie to noise and require good grounding and shielding. It'll be difficult to get good performance out of a conventional protoboard with no ground plane.
Risks and challenges
Risks are very low. We've been using these kind of prototype boards for almost 8 years. I have a few of them at hand right now. They work really well.Learn about accountability on Kickstarter
