On each perimeter of the PC board, ensure a circuit-free zone of 0.5inches. In addition, preserve the edge finger area to boost the sharpness of the layout and ease manufacturability.

Add a spacing for framing.

Voltage Spacing

There should be a minimum of 0.010 inches line spaces for differentials of less than 50 volts on a standard.

Plated Thru-holes

  • Due to manufacturing issues, you should avoid holes diameter below 0.031inches.
  • It would help if you prevented numerous drill bit changes by reducing the number of different holes.
  • The hole diameter ratio to board thickness should be a maximum of 1:3.
  • For quality soldering and quick component loading, let the plated thru holes be 0.010 inches diagonal of the sockets

Pad Areas Around Plated Thru-holes

Your design should have at least 50% padded area around the plated thru-holes to have good solder joints.


  • Ensure you bus the voltage and ground buses at the top and bottom of every device on the BIB board.
  • You can reduce the effective inductance of the system by providing several paths through the array.
  • The traces that run the power supply voltage should be very wide within the array

Die Entkoppelung

For local decoupling, use a 0.1 microfarad capacitor per DUT to overcome high frequencies that affect the voltage spikes.

Place the local decoupling capacitor close to each chip.

For bulk coupling, use a capacitor range of 46-200 microfarads to enable low-frequency coupling.

Other guidelines include;

  • For multilayer design, reduce the use of vias to boost circuit performance
  • Use conformal coating for board areas that need high insulation, or have high humidity and atmospheric contaminants.
