Manhattan style PCB board prototyping for high frequency RF and critical circuits
If you want to build RF high frequency or critical circuits, such as extremely high gain
audio amplifiers, and you want to avoid to etch PCB's or a print board service, a normal
breadboard is not suitable. Stray fields will cause interference,
increase noise and/or cause feedback with oscillation.
The solution is Manhattan style prototyping!
* Use a single or double layer epoxide or hard paper board with full copper coating
* The copper coating will act as ground plane to avoid cross-talk, feedback etc.
* Use standoff terminals to solder components (cut small round, square or rectangle pieces out
of some other board material and glue them on the ground plane - solder the components atop these)
* Seperate different amplifier stages and mixed signal (analog, digital) stages with either
thin strips of copper clad board or stripes of some solderable sheet metal.
Don't forget to close those shielded chambers with a lid of the same material.
* Decoupling the power supply
