Have a technical question, ask 3M's UHM expert Roland Nuiten

Roland,

     I am researching possible board to board connections for a design change that I am working on.  Currently we utilize a multilayer mixed signal board that has some issues with noise from the transmitter section being transferred to the ground plane.  I would like to isolate the transmit section with an air mote around the entire section and move it from a four layer to a two layer.  My connection questions come from the most efficient way to transfer the 3v transmit initiation pulses along with the monitoring signals to and from the floating daughter board.  Also the transfer of the positive and negative 24V power supply voltages across the gap.  The maximum frequency of the pulses is 40kHz, so it is very low in the realm of skin effect.  Most of the systems will be operating at 10kHz down to 350HZ.  The transmit section power requirements would be less that 400mA for each supply.  Would a board to board riser connection be a better option or a copper ribbon be a better design with respect to the power and signal range?
